glpi -- Public GLPIKEY can be used to decrypt any data glpi 9.4.6

MITRE Corporation reports:

GLPI before before version 9.4.6 has a vulnerability involving a default encryption key. GLPIKEY is public and is used on every instance. This means anyone can decrypt sensitive data stored using this key. It is possible to change the key before installing GLPI. But on existing instances, data must be reencrypted with the new key. Problem is we can not know which columns or rows in the database are using that; espcially from plugins. Changing the key without updating data would lend in bad password sent from glpi; but storing them again from the UI will work.

FreeBSD -- Multiple vulnerabilities in rtsold FreeBSD 12.212.2_1 12.112.1_11 11.411.4_5

Problem Description:

Two bugs exist in rtsold(8)'s RDNSS and DNSSL option handling. First, rtsold(8) failed to perform sufficient bounds checking on the extent of the option. In particular, it does not verify that the option does not extend past the end of the received packet before processing its contents. The kernel currently ignores such malformed packets but still passes them to userspace programs.

Second, when processing a DNSSL option, rtsold(8) decodes domain name labels per an encoding specified in RFC 1035 in which the first octet of each label contains the label's length. rtsold(8) did not validate label lengths correctly and could overflow the destination buffer.

Impact:

It is believed that these bugs could be exploited to gain remote code execution within the rtsold(8) daemon, which runs as root. Note that rtsold(8) only processes messages received from hosts attached to the same physical link as the interface(s) on which rtsold(8) is listening.

In FreeBSD 12.2 rtsold(8) runs in a Capsicum sandbox, limiting the scope of a compromised rtsold(8) process.

FreeBSD -- ICMPv6 use-after-free in error message handling FreeBSD-kernel 12.212.2_1 12.112.1_11 11.411.4_5

Problem Description:

When an ICMPv6 error message is received, the FreeBSD ICMPv6 stack may extract information from the message to hand to upper-layer protocols. As a part of this operation, it may parse IPv6 header options from a packet embedded in the ICMPv6 message.

The handler for a routing option caches a pointer into the packet buffer holding the ICMPv6 message. However, when processing subsequent options the packet buffer may be freed, rendering the cached pointer invalid. The network stack may later dereference the pointer, potentially triggering a use-after-free.

Impact:

A remote host may be able to trigger a read of freed kernel memory. This may trigger a kernel panic if the address had been unmapped.

go -- math/big: panic during recursive division of very large numbers; cmd/go: arbitrary code execution at build time through cgo go 1.15.5,1

The Go project reports:

A number of math/big.Int methods (Div, Exp, DivMod, Quo, Rem, QuoRem, Mod, ModInverse, ModSqrt, Jacobi, and GCD) can panic when provided crafted large inputs. For the panic to happen, the divisor or modulo argument must be larger than 3168 bits (on 32-bit architectures) or 6336 bits (on 64-bit architectures). Multiple math/big.Rat methods are similarly affected.

The go command may execute arbitrary code at build time when cgo is in use. This may occur when running go get on a malicious package, or any other command that builds untrusted code. This can be caused by a malicious gcc flags specified via a #cgo directive.

The go command may execute arbitrary code at build time when cgo is in use. This may occur when running go get on a malicious package, or any other command that builds untrusted code. This can be caused by malicious unquoted symbol names.

Apache OpenOffice -- Unrestricted actions leads to arbitrary code execution in crafted documents apache-openoffice 4.1.8 apache-openoffice-devel 4.2.1602022694,4

The Apache Openofffice project reports:

CVE-2020-13958 Unrestricted actions leads to arbitrary code execution in crafted documents

Description

A vulnerability in Apache OpenOffice scripting events allows an attacker to construct documents containing hyperlinks pointing to an executable on the target users file system. These hyperlinks can be triggered unconditionally. In fixed versions no internal protocol may be called from the document event handler and other hyperlinks require a control-click.

Severity: Low

There are no known exploits of this vulnerability.
A proof-of-concept demonstration exists.

Thanks to the reporter for discovering this issue.

Acknowledgments

The Apache OpenOffice Security Team would like to thank Imre Rad for discovering and reporting this attack vector.

asterisk -- Outbound INVITE loop on challenge with different nonce asterisk13 13.37.1 asterisk16 16.14.1 asterisk18 18.0.1

The Asterisk project reports:

If Asterisk is challenged on an outbound INVITE and the nonce is changed in each response, Asterisk will continually send INVITEs in a loop. This causes Asterisk to consume more and more memory since the transaction will never terminate (even if the call is hung up), ultimately leading to a restart or shutdown of Asterisk. Outbound authentication must be configured on the endpoint for this to occur.

asterisk -- Remote crash in res_pjsip_session asterisk13 13.37.1 asterisk16 16.14.1 asterisk18 18.0.1

The Asterisk project reports:

Upon receiving a new SIP Invite, Asterisk did not return the created dialog locked or referenced. This caused a gap between the creation of the dialog object, and its next use by the thread that created it. Depending upon some off nominal circumstances, and timing it was possible for another thread to free said dialog in this gap. Asterisk could then crash when the dialog object, or any of its dependent objects were de-referenced, or accessed next by the initial creation thread.

kdeconnect -- packet manipulation can be exploited in a Denial of Service attack kdeconnect-kde 20.08.1

Albert Astals Cid reports:

KDE Project Security Advisory

Title KDE Connect: packet manipulation can be exploited in a Denial of Service attack
Risk Rating Important
CVE CVE-2020-26164
Versions kdeconnect <= 20.08.1
Author Albert Vaca Cintora <albertvaka@gmail.com>
Date 2 October 2020

Overview

An attacker on your local network could send maliciously crafted packets to other hosts running kdeconnect on the network, causing them to use large amounts of CPU, memory or network connections, which could be used in a Denial of Service attack within the network.

Impact

Computers that run kdeconnect are susceptible to DoS attacks from the local network.

Workaround

We advise you to stop KDE Connect when on untrusted networks like those on airports or conferences.

Since kdeconnect is dbus activated it is relatively hard to make sure it stays stopped so the brute force approach is to uninstall the kdeconnect package from your system and then run

	      kquitapp5 kdeconnectd
	  

Just install the package again once you're back in a trusted network.

Solution

KDE Connect 20.08.2 patches several code paths that could result in a DoS.

You can apply these patches on top of 20.08.1:

Apache Ant leaks sensitive information via the java.io.tmpdir apache-ant 1.11.10.8

Apache reports:

Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process.

py-matrix-synapse -- malformed events may prevent users from joining federated rooms py36-matrix-synapse py37-matrix-synapse py38-matrix-synapse 1.19.2

Problem Description:

Affected Synapse versions assume that all events have an "origin" field set. If an event without the "origin" field is sent into a federated room, servers not already joined to the room will be unable to do so due to failing to fetch the malformed event.

Impact:

An attacker could cause a denial of service by deliberately sending a malformed event into a room, thus preventing new servers (and thus their users) from joining the room.

Node.js -- September 2020 Security Releases node 14.11.0 node12 12.18.4 node10 10.22.1

Node.js reports:

Updates are now available for v10,x, v12.x and v14.x Node.js release lines for the following issues.

HTTP Request Smuggling due to CR-to-Hyphen conversion (High) (CVE-2020-8201)

Affected Node.js versions converted carriage returns in HTTP request headers to a hyphen before parsing. This can lead to HTTP Request Smuggling as it is a non-standard interpretation of the header.

Impacts:

  • All versions of the 14.x and 12.x releases line

Denial of Service by resource exhaustion CWE-400 due to unfinished HTTP/1.1 requests (Critical) (CVE-2020-8251)

Node.js is vulnerable to HTTP denial of service (DOS) attacks based on delayed requests submission which can make the server unable to accept new connections. The fix a new http.Server option called requestTimeout with a default value of 0 which means it is disabled by default. This should be set when Node.js is used as an edge server, for more details refer to the documentation.

Impacts:

  • All versions of the 14.x release line

fs.realpath.native on may cause buffer overflow (Medium) (CVE-2020-8252)

libuv's realpath implementation incorrectly determined the buffer size which can result in a buffer overflow if the resolved path is longer than 256 bytes.

Impacts:

  • All versions of the 10.x release line
  • All versions of the 12.x release line
  • All versions of the 14.x release line before 14.9.0

FreeBSD -- ftpd privilege escalation via ftpchroot feature FreeBSD 12.112.1_10 11.411.4_4 11.311.3_14

Problem Description:

A ftpd(8) bug in the implementation of the file system sandbox, combined with capabilities available to an authenticated FTP user, can be used to escape the file system restriction configured in ftpchroot(5). Moreover, the bug allows a malicious client to gain root privileges.

Impact:

A malicious FTP user can gain privileged access to an affected system.

CVE-2020-7468 SA-20:30.ftpd 2020-09-15 2020-09-16
FreeBSD -- bhyve SVM guest escape FreeBSD-kernel 12.112.1_10 11.411.4_4 11.311.3_14

Problem Description:

A number of AMD virtualization instructions operate on host physical addresses, are not subject to nested page table translation, and guest use of these instructions was not trapped.

Impact:

From kernel mode a malicious guest can write to arbitrary host memory (with some constraints), affording the guest full control of the host.

CVE-2020-7467 SA-20:29.bhyve_svm 2020-09-15 2020-09-16
FreeBSD -- bhyve privilege escalation via VMCS access FreeBSD-kernel 12.112.1_10 11.411.4_4 11.311.3_14

Problem Description:

AMD and Intel CPUs support hardware virtualization using specialized data structures that control various aspects of guest operation. These are the Virtual Machine Control Structure (VMCS) on Intel CPUs, and the Virtual Machine Control Block (VMCB) on AMD CPUs. Insufficient access controls allow root users, including those running in a jail, to change these data structures.

Impact:

An attacker with host root access (including to a jailed bhyve instance) can use this vulnerability to achieve kernel code execution.

CVE-2020-24718 SA-20:28.bhyve_vmcs 2020-09-15 2020-09-16
FreeBSD -- ure device driver susceptible to packet-in-packet attack FreeBSD-kernel 12.112.1_10 11.411.4_4 11.311.3_14

Problem Description:

A programming error in the ure(4) device driver caused some Realtek USB Ethernet interfaces to incorrectly report packets with more than 2048 bytes in a single USB transfer as having a length of only 2048 bytes.

An adversary can exploit this to cause the driver to misinterpret part of the payload of a large packet as a separate packet, and thereby inject packets across security boundaries such as VLANs.

Impact:

An attacker that can send large frames (larger than 2048 bytes in size) to be received by the host (be it VLAN, or non-VLAN tagged packet), can inject arbitrary packets to be received and processed by the host. This includes spoofing packets from other hosts, or injecting packets to other VLANs than the host is on.

Multi-link PPP protocol daemon MPD5 remotely exploitable crash mpd5 5.9

Version 5.9 contains security fix for L2TP clients and servers. Insufficient validation of incoming L2TP control packet specially crafted by unauthenticated user might lead to unexpected termination of the process. The problem affects mpd versions since 4.0 that brought in initial support for L2TP. Installations not using L2TP clients nor L2TP server configuration were not affected.

Mbed TLS -- Local side channel attack on RSA and static Diffie-Hellman mbedtls 2.16.8

Manuel Pégourié-Gonnard reports:

An attacker with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world) can recover the private keys used in RSA or static (finite-field) Diffie-Hellman operations.

Mbed TLS -- Local side channel attack on classical CBC decryption in (D)TLS mbedtls 2.16.8

Manuel Pégourié-Gonnard reports:

When decrypting/authenticating (D)TLS record in a connection using a CBC ciphersuite without the Encrypt-then-Mac extension RFC 7366, Mbed TLS used dummy rounds of the compression function associated with the hash used for HMAC in order to hide the length of the padding to remote attackers, as recommended in the original Lucky Thirteen paper.

A local attacker who is able to observe the state of the cache could monitor the presence of mbedtls_md_process() in the cache in order to determine when the actual computation ends and when the dummy rounds start. This is a reliable target as it's always called at least once, in response to a previous attack. The attacker can then continue with one of many well-documented Lucky 13 variants.

https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2020-09-1 CVE-2020-16150 2020-09-01 2020-09-06
GnuTLS -- null pointer dereference gnutls 3.6.15

The GnuTLS project reports:

It was found by oss-fuzz that the server sending a "no_renegotiation" alert in an unexpected timing, followed by an invalid second handshake can cause a TLS 1.3 client to crash via a null-pointer dereference. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure.

Django Release notes:

CVE-2020-24583: Incorrect permissions on intermediate-level directories on Python 3.7+

On Python 3.7+, FILE_UPLOAD_DIRECTORY_PERMISSIONS mode was not applied to intermediate-level directories created in the process of uploading files and to intermediate-level collected static directories when using the collectstatic management command.

CVE-2020-24584: Permission escalation in intermediate-level directories of the file system cache on Python 3.7+

On Python 3.7+, the intermediate-level directories of the file system cache had the system's standard umask rather than 0o077 (no group or others permissions).

gnupg -- AEAD key import overflow gnupg 2.2.212.2.23

Importing an OpenPGP key having a preference list for AEAD algorithms will lead to an array overflow and thus often to a crash or other undefined behaviour.

Importing an arbitrary key can often easily be triggered by an attacker and thus triggering this bug. Exploiting the bug aside from crashes is not trivial but likely possible for a dedicated attacker. The major hurdle for an attacker is that only every second byte is under their control with every first byte having a fixed value of 0x04.

CVE-2020-25125 https://dev.gnupg.org/T5050 2020-09-03 2020-09-03
FreeBSD -- dhclient heap overflow FreeBSD 12.112.1_9 11.411.4_3 11.311.3_13

Problem Description:

When parsing option 119 data, dhclient(8) computes the uncompressed domain list length so that it can allocate an appropriately sized buffer to store the uncompressed list. The code to compute the length failed to handle certain malformed input, resulting in a heap overflow when the uncompressed list is copied into in inadequately sized buffer.

Impact:

The heap overflow could in principle be exploited to achieve remote code execution. The affected process runs with reduced privileges in a Capsicum sandbox, limiting the immediate impact of an exploit. However, it is possible the bug could be combined with other vulnerabilities to escape the sandbox.

CVE-2020-7461 SA-20:26.dhclient 2020-09-02 2020-09-02
FreeBSD -- SCTP socket use-after-free bug FreeBSD-kernel 12.112.1_9 11.411.4_3 11.311.3_13

Problem Description:

Due to improper handling in the kernel, a use-after-free bug can be triggered by sending large user messages from multiple threads on the same socket.

Impact:

Triggering the use-after-free situation may result in unintended kernel behaviour including a kernel panic.

CVE-2020-7463 SA-20:25.sctp 2020-09-02 2020-09-02
FreeBSD -- IPv6 Hop-by-Hop options use-after-free bug FreeBSD-kernel 11.311.3_13

Problem Description:

Due to improper mbuf handling in the kernel, a use-after-free bug might be triggered by sending IPv6 Hop-by-Hop options over the loopback interface.

Impact:

Triggering the use-after-free situation may result in unintended kernel behaviour including a kernel panic.

go -- net/http/cgi, net/http/fcgi: Cross-Site Scripting (XSS) when Content-Type is not specified go 1.14.8,1 1.15,11.15.1,1

The Go project reports:

When a Handler does not explicitly set the Content-Type header, both CGI implementations default to “text/html”. If an attacker can make a server generate content under their control (e.g. a JSON containing user data or an uploaded image file) this might be mistakenly returned by the server as “text/html”. If a victim visits such a page they could get the attacker's code executed in the context of the server origin.

ark -- extraction outside of extraction directory ark 20.08.0_1

Albert Astals Cid reports:

Overview

A maliciously crafted TAR archive containing symlink entries would install files anywhere in the user's home directory upon extraction.

Proof of concept

For testing, an example of malicious archive can be found at dirsymlink.tar

Impact

Users can unwillingly install files like a modified .bashrc, or a malicious script placed in ~/.config/autostart.

Workaround

Before extracting a downloaded archive using the Ark GUI, users should inspect it to make sure it doesn't contain symlink entries pointing outside the extraction folder.

The 'Extract' context menu from the Dolphin file manager shouldn't be used.

Solution

Ark 20.08.1 skips maliciously crafted symlinks when extracting TAR archives.

Alternatively, 8bf8c5ef07b0ac5e914d752681e470dea403a5bd can be applied to previous releases.

chrony <= 3.5.1 data corruption through symlink vulnerability writing the pidfile chrony 3.5.1

Miroslav Lichvar reports:

chrony-3.5.1 [...] fixes a security issue in writing of the pidfile.

When chronyd is configured to save the pidfile in a directory where the chrony user has write permissions (e.g. /var/run/chrony - the default since chrony-3.4), an attacker that compromised the chrony user account could create a symbolic link at the location of the pidfile to make chronyd starting with root privileges follow the symlink and write its process ID to a file for which the chrony user doesn't have write permissions, causing a denial of service, or data loss.

This issue was reported by Matthias Gerstner of SUSE.

Users are always granted permissions to cd into a directory. The check for whether execute is present on directories is a de-facto no-op. This cannot be mitigated without upgrading. Even setting an explicit "deny - execute" NFSv4 ACE will be bypassed.

Issue 2:

All ACEs for the owner_group (group@) and regular groups (group:<foo>) are granted the current user. This means that POSIX mode 770 is de-facto 777, and the below ACL is also de-facto 777 because the groupmember check for builtin_administrators returns True.

textproc/elasticsearch6 -- field disclosure flaw elasticsearch6 6.8.12

Elastic reports:

A field disclosure flaw was found in Elasticsearch when running a scrolling search with Field Level Security. If a user runs the same query another more privileged user recently ran, the scrolling search can leak fields that should be hidden. This could result in an attacker gaining additional permissions against a restricted index.

Icinga Web 2 -- directory traversal vulnerability icingaweb2 2.8.1

Icinga development team reports:

CVE-2020-24368

Icinga Icinga Web2 2.0.0 through 2.6.4, 2.7.4 and 2.8.2 has a Directory Traversal vulnerability which allows an attacker to access arbitrary files that are readable by the process running Icinga Web 2. This issue is fixed in Icinga Web 2 in v2.6.4, v2.7.4 and v2.8.2.

curl -- expired pointer dereference vulnerability curl 7.29.07.72.0

curl security problems:

CVE-2020-8231: wrong connect-only connection

An application that performs multiple requests with libcurl's multi API and sets the CURLOPT_CONNECT_ONLY option, might in rare circumstances experience that when subsequently using the setup connect-only transfer, libcurl will pick and use the wrong connection - and instead pick another one the application has created since then.

CURLOPT_CONNECT_ONLY is the option to tell libcurl to not perform an actual transfer, only connect. When that operation is completed, libcurl remembers which connection it used for that transfer and "easy handle". It remembers the connection using a pointer to the internal connectdata struct in memory.

If more transfers are then done with the same multi handle before the connect-only connection is used, leading to the initial connect-only connection to get closed (for example due to idle time-out) while also new transfers (and connections) are setup, such a new connection might end up getting the exact same memory address as the now closed connect-only connection.

If after those operations, the application then wants to use the original transfer's connect-only setup to for example use curl_easy_send() to send raw data over that connection, libcurl could erroneously find an existing connection still being alive at the address it remembered since before even though this is now a new and different connection.

The application could then accidentally send data over that connection which wasn't at all intended for that recipient, entirely unknowingly.

FreeBSD -- sendmsg(2) privilege escalation FreeBSD-kernel 12.112.1_8 11.411.4_2 11.311.3_12

Problem Description:

When handling a 32-bit sendmsg(2) call, the compat32 subsystem copies the control message to be transmitted (if any) into kernel memory, and adjusts alignment of control message headers. The code which performs this work contained a time-of-check to time-of-use (TOCTOU) vulnerability which allows a malicious userspace program to modify control message headers after they were validated by the kernel.

Impact:

The TOCTOU bug can be exploited by an unprivileged malicious userspace program to trigger privilege escalation.

Impact:

An attacker with physical access to a USB port and the ability to bring a network interface up may be able to use a specially crafted USB device to gain kernel or user-space code execution.

Typo3 Team reports:

In case an attacker manages to generate a valid cryptographic message authentication code (HMAC-SHA1) - either by using a different existing vulnerability or in case the internal encryptionKey was exposed - it is possible to retrieve arbitrary files of a TYPO3 installation. This includes the possibility to fetch typo3conf/LocalConfiguration.php which again contains the encryptionKey as well as credentials of the database management system being used. In case a database server is directly accessible either via internet or in a shared hosting network, this allows to completely retrieve, manipulate or delete database contents. This includes creating an administration user account - which can be used to trigger remote code execution by injecting custom extensions.

It has been discovered that an internal verification mechanism can be used to generate arbitrary checksums. This allows to inject arbitrary data having a valid cryptographic message authentication code (HMAC-SHA1) and can lead to various attack chains as described below.

ark -- directory traversal ark 20.04.2_1 20.04.3

KDE Project Security Advisory reports:

KDE Project Security Advisory

Title: Ark: maliciously crafted archive can install files outside the extraction directory.
Risk Rating: Important
CVE: CVE-2020-16116
Versions: ark <= 20.04.3
Author: Elvis Angelaccio <elvis.angelaccio@kde.org>
Date: 30 July 2020

Overview

A maliciously crafted archive with "../" in the file paths would install files anywhere in the user's home directory upon extraction.

Proof of concept

For testing, an example of malicious archive can be found at https://github.com/jwilk/traversal-archives/releases/download/0/relative2.zip

Impact

Users can unwillingly install files like a modified .bashrc, or a malicious script placed in ~/.config/autostart

Workaround

Users should not use the 'Extract' context menu from the Dolphin file manager. Before extracting a downloaded archive using the Ark GUI, users should inspect it to make sure it doesn't contain entries with "../" in the file path.

Solution

Ark 20.08.0 prevents loading of malicious archives and shows a warning message to the users.

Alternatively, https://invent.kde.org/utilities/ark/-/commit/0df592524fed305d6fbe74ddf8a196bc9ffdb92f can be applied to previous releases.

Credits

Thanks to Dominik Penner for finding and reporting this issue and thanks to Elvis Angelaccio and Albert Astals Cid for fixing it.

Wagtail -- XSS vulnerability py36-wagtail py37-wagtail py38-wagtail 2.8.02.9.3 2.7.4

GitHub Advisory Database:

When a form page type is made available to Wagtail editors through the wagtail.contrib.forms app, and the page template is built using Django's standard form rendering helpers such as form.as_p (as directed in the documentation), any HTML tags used within a form field's help text will be rendered unescaped in the page. Allowing HTML within help text is an intentional design decision by Django; however, as a matter of policy Wagtail does not allow editors to insert arbitrary HTML by default, as this could potentially be used to carry out cross-site scripting attacks, including privilege escalation. This functionality should therefore not have been made available to editor-level users.

The vulnerability is not exploitable by an ordinary site visitor without access to the Wagtail admin.

clamav -- multiple vulnerabilities clamav 0.102.4,1

Micah Snyder reports:

CVE-2020-3350
Fixed a vulnerability a malicious user could exploit to replace a scan target's directory with a symlink to another path to trick clamscan, clamdscan, or clamonacc into removing or moving a different file (such as a critical system file). The issue would affect users that use the --move or --remove options for clamscan, clamdscan and clamonacc.
CVE-2020-3327
Fixed a vulnerability in the ARJ archive-parsing module in ClamAV 0.102.3 that could cause a denial-of-service (DoS) condition. Improper bounds checking resulted in an out-of-bounds read that could cause a crash. The previous fix for this CVE in version 0.102.3 was incomplete. This fix correctly resolves the issue.
CVE-2020-3481
Fixed a vulnerability in the EGG archive module in ClamAV 0.102.0 - 0.102.3 that could cause a denial-of-service (DoS) condition. Improper error handling could cause a crash due to a NULL pointer dereference. This vulnerability is mitigated for those using the official ClamAV signature databases because the file type signatures in daily.cvd will not enable the EGG archive parser in affected versions.

FreeBSD -- IPv6 socket option race condition and use after free FreeBSD-kernel 12.112.1_7 11.411.4_1 11.311.3_11

Problem Description:

The IPV6_2292PKTOPTIONS set handler was missing synchronization, so racing accesses could modify freed memory.

Impact:

A malicious user application could trigger memory corruption, leading to privilege escalation.

CVE-2020-7457 SA-20:20.ipv6 2020-07-09 2020-07-10
FreeBSD -- posix_spawnp(3) buffer overflow FreeBSD 11.411.4_1

Problem Description:

posix_spawnp spawns a new thread with a limited stack allocated on the heap before delegating to execvp for the final execution within that thread.

execvp would previously make unbounded allocations on the stack, directly proportional to the length of the user-controlled PATH environment variable.

Impact:

Long values in the user-controlled PATH environment variable cause posix_spawnp to write beyond the end of stack that was allocated, ultimately overflowing the heap-allocated stack with a direct copy of the value stored in PATH.

Mbed TLS -- Side-channel attack on ECC key import and validation mbedtls 2.16.7

Manuel Pégourié-Gonnard reports:

The scalar multiplication function in Mbed TLS accepts a random number generator (RNG) as an optional argument and, if provided, uses it to protect against some attacks.

It is the caller's responsibility to provide a RNG if protection against side-channel attacks is desired; however two groups of functions in Mbed TLS itself fail to pass a RNG:

  1. mbedtls_pk_parse_key() and mbedtls_pk_parse_keyfile()
  2. mbedtls_ecp_check_pub_priv() and mbedtls_pk_check_pair()

When those functions are called, scalar multiplication is computed without randomisation, a number of old and new attacks apply, allowing a powerful local attacker to fully recover the private key.

Due to the two security issues highlighted below, server administrators are encouraged to update Synapse. We are not aware of these vulnerabilities being exploited in the wild.

  • A malicious homeserver could force Synapse to reset the state in a room to a small subset of the correct state. This affects all Synapse deployments which federate with untrusted servers.
  • HTML pages served via Synapse were vulnerable to clickjacking attacks. This predominantly affects homeservers with single-sign-on enabled, but all server administrators are encouraged to upgrade.

Simon Tatham reports:

[Release 0.74] fixes the following security issues:

  • New configuration option to disable PuTTY's default policy of changing its host key algorithm preferences to prefer keys it already knows. (There is a theoretical information leak in this policy.) [CVE-2020-14002]
  • In some situations an SSH server could cause PuTTY to access freed mdmory by pretending to accept an SSH key and then refusing the actual signature. It can only happen if you're using an SSH agent.

curl -- multiple vulnerabilities curl 7.20.07.71.0

curl security problems:

CVE-2020-8169: Partial password leak over DNS on HTTP redirect

libcurl can be tricked to prepend a part of the password to the host name before it resolves it, potentially leaking the partial password over the network and to the DNS server(s).

libcurl can be given a username and password for HTTP authentication when requesting an HTTP resource - used for HTTP Authentication such as Basic, Digest, NTLM and similar. The credentials are set, either together with CURLOPT_USERPWD or separately with CURLOPT_USERNAME and CURLOPT_PASSWORD. Important detail: these strings are given to libcurl as plain C strings and they are not supposed to be URL encoded.

In addition, libcurl also allows the credentials to be set in the URL, using the standard RFC 3986 format: http://user:password@host/path. In this case, the name and password are URL encoded as that's how they appear in URLs.

If the options are set, they override the credentials set in the URL.

Internally, this is handled by storing the credentials in the "URL object" so that there is only a single set of credentials stored associated with this single URL.

When libcurl handles a relative redirect (as opposed to an absolute URL redirect) for an HTTP transfer, the server is only sending a new path to the client and that path is applied on to the existing URL. That "applying" of the relative path on top of an absolute URL is done by libcurl first generating a full absolute URL out of all the components it has, then it applies the redirect and finally it deconstructs the URL again into its separate components.

This security vulnerability originates in the fact that curl did not correctly URL encode the credential data when set using one of the curl_easy_setopt options described above. This made curl generate a badly formatted full URL when it would do a redirect and the final re-parsing of the URL would then go bad and wrongly consider a part of the password field to belong to the host name.

The wrong host name would then be used in a name resolve lookup, potentially leaking the host name + partial password in clear text over the network (if plain DNS was used) and in particular to the used DNS server(s).

CVE-2020-8177: curl overwrite local file with -J

curl can be tricked by a malicious server to overwrite a local file when using -J (--remote-header-name) and -i (--include) in the same command line.

The command line tool offers the -J option that saves a remote file using the file name present in the Content-Disposition: response header. curl then refuses to overwrite an existing local file using the same name, if one already exists in the current directory.

The -J flag is designed to save a response body, and so it doesn't work together with -i and there's logic that forbids it. However, the check is flawed and doesn't properly check for when the options are used in the reversed order: first using -J and then -i were mistakenly accepted.

The result of this mistake was that incoming HTTP headers could overwrite a local file if one existed, as the check to avoid the local file was done first when body data was received, and due to the mistake mentioned above, it could already have received and saved headers by that time.

The saved file would only get response headers added to it, as it would abort the saving when the first body byte arrives. A malicious server could however still be made to send back virtually anything as headers and curl would save them like this, until the first CRLF-CRLF sequence appears.

(Also note that -J needs to be used in combination with -O to have any effect.)

BIND -- Remote Denial of Service vulnerability bind911 9.11.149.11.20 bind916 9.16.09.16.4

ISC reports:

The asterisk character ("*") is allowed in DNS zone files, where it is most commonly present as a wildcard at a terminal node of the Domain Name System graph. However, the RFCs do not require and BIND does not enforce that an asterisk character be present only at a terminal node.

A problem can occur when an asterisk is present in an empty non-terminal location within the DNS graph. If such a node exists, after a series of queries, named can reach an inconsistent state that results in the failure of an assertion check in rbtdb.c, followed by the program exiting due to the assertion failure.

Node.js -- June 2020 Security Releases node 14.4.0 node12 12.18.0 node10 10.21.0

Node.js reports:

Updates are now available for all supported Node.js release lines for the following issues.

TLS session reuse can lead to host certificate verification bypass (High) (CVE-2020-8172)

The 'session' event could be emitted before the 'secureConnect' event. It should not be, because the connection may fail to be authorized. If it was saved an authorized connection could be established later with the session ticket. Note that the https agent caches sessions, so is vulnerable to this.

The 'session' event will now only be emitted after the 'secureConnect' event, and only for authorized connections.

HTTP/2 Large Settings Frame DoS (Low) (CVE-2020-11080)

Receiving unreasonably large HTTP/2 SETTINGS frames can consume 100% CPU to process all the settings, blocking all other activities until complete.

The HTTP/2 session frame is limited to 32 settings by default. This can be configured if necessary using the maxSettings option.

napi_get_value_string_*() allows various kinds of memory corruption (High) (CVE-2020-8174)

Calling napi_get_value_string_latin1(), napi_get_value_string_utf8(), or napi_get_value_string_utf16() with a non-NULL buf, and a bufsize of 0 will cause the entire string value to be written to buf, probably overrunning the length of the buffer.

A exploit has not been reported and it may be difficult but the following is suggested:

  • All users of LTS Node.js versions should update to the versions announced in this security post. This will address the issue for any non pre-built add-on.
  • Maintainers who support EOL Node.js versions and/or build against a version of Node.js that did not support N-API internally should update to use the new versions of node-addon-api 1.x and 2.x that will be released soon after this announcement.

ICU-20958 Prevent SEGV_MAPERR in append (High) (CVE-2020-10531)

An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1. An integer overflow, leading to a heap-based buffer overflow, exists in the UnicodeString::doAppend() function in common/unistr.cpp.

Fix was applied to 10.x in an abundance of caution, even though there is no known way to trigger the overflow in 10.x.

sympa -- Denial of service caused by malformed CSRF token sympa 6.2.54

Javier Moreno discovered a vulnerability in Sympa web interface that can cause denial of service (DoS) attack.

By submitting requests with malformed parameters, this flaw allows to create junk files in Sympa's directory for temporary files. And particularly by tampering token to prevent CSRF, it allows to originate exessive notification messages to listmasters.

sympa - Security flaws in setuid wrappers sympa 6.2.56

A vulnerability has been discovered in Sympa web interface by which attacker can execute arbitrary code with root privileges. Sympa uses two sorts of setuid wrappers:

The FastCGI wrappers wwsympa-wrapper.fcgi and sympa_soap_server-wrapper.fcgi were used to make the web interface running under privileges of a dedicated user.

The newaliases wrapper (sympa_newaliases-wrapper) allows Sympa to update the alias database with root privileges.

Since these setuid wrappers did not clear environment variables, if environment variables like PERL5LIB were injected, forged code might be loaded and executed under privileges of setuid-ed users.

powerdns-recursor -- multiple vulnerabilities powerdns-recursor 4.3.04.3.1 4.2.04.2.2 4.1.04.1.16

PowerDNS Team reports:

CVE-2020-10995: An issue in the DNS protocol has been found that allow malicious parties to use recursive DNS services to attack third party authoritative name servers. The attack uses a crafted reply by an authoritative name server to amplify the resulting traffic between the recursive and other authoritative name servers. Both types of service can suffer degraded performance as an effect.

CVE-2020-12244: An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer. This would allow an attacker in position of man-in-the-middle to send a NXDOMAIN answer for a name that does exist, bypassing DNSSEC validation.

CVE-2020-10030: An issue has been found in PowerDNS Authoritative Server allowing an attacker with enough privileges to change the system's hostname to cause disclosure of uninitialized memory content via a stack-based out-of-bounds read. It only occurs on systems where gethostname() does not null-terminate the returned string if the hostname is larger than the supplied buffer. Linux systems are not affected because the buffer is always large enough. OpenBSD systems are not affected because the returned hostname is always null-terminated. Under some conditions this issue can lead to the writing of one null-byte out-of-bounds on the stack, causing a denial of service or possibly arbitrary code execution.

drupal -- Multiple Vulnerabilities drupal7 7.70 drupal8 8.8.6

Drupal Security Team reports:

The jQuery project released version 3.5.0, and as part of that, disclosed two security vulnerabilities that affect all prior versions. As mentioned in the jQuery blog, both are: ... Security issues in jQuerys DOM manipulation methods, as in .html(), .append(), and the others. Security advisories for both of these issues have been published on GitHub.

Drupal 7 has an Open Redirect vulnerability. For example, a user could be tricked into visiting a specially crafted link which would redirect them to an arbitrary external URL. The vulnerability is caused by insufficient validation of the destination query parameter in the drupal_goto() function.

Dovecot -- Multiple vulnerabilities dovecot 2.3.10.1

Aki Tuomi reports:

Vulnerability Details: Sending malformed NOOP command causes crash in submission, submission-login or lmtp service. Risk: Remote attacker can keep submission-login service down, causing denial of service attack. For lmtp the risk is neglible, as lmtp is usually behind a trusted MTA. Steps to reproduce: Send ``NOOP EE"FY`` to submission port, or similarly malformed command.

Vulnerability Details: Sending command followed by sufficient number of newlines triggers a use-after-free bug that might crash submission-login, submission or lmtp service. Risk: Remote attacker can keep submission-login service down, causing denial of service attack. For lmtp the risk is neglible, as lmtp is usually behind a trusted MTA. Steps to reproduce: This can be currently reproduced with ASAN or Valgrind. Reliable way to crash has not yet been discovered.

Vulnerability Details: Sending mail with empty quoted localpart causes submission or lmtp component to crash. Risk: Malicious actor can cause denial of service to mail delivery by repeatedly sending mails with bad sender or recipient address. Steps to reproduce: Send mail with envelope sender or recipient as <""@example.org>. Workaround: For submission there is no workaround, but triggering the bug requires valid credentials. For lmtp, one can implement sufficient filtering on MTA level to prevent mails with such addresses from ending up in LMTP delivery.

F-Secure reports:

CVE-2020-11651 - Authentication bypass vulnerabilities

The ClearFuncs class processes unauthenticated requests and unintentionally exposes the _send_pub() method, which can be used to queue messages directly on the master publish server. Such messages can be used to trigger minions to run arbitrary commands as root.

The ClearFuncs class also exposes the method _prep_auth_info(), which returns the "root key" used to authenticate commands from the local root user on the master server. This "root key" can then be used to remotely call administrative commands on the master server. This unintentional exposure provides a remote un-authenticated attacker with root-equivalent access to the salt master.

CVE-2020-11652 - Directory traversal vulnerabilities

The wheel module contains commands used to read and write files under specific directory paths. The inputs to these functions are concatenated with the target directory and the resulting path is not canonicalized, leading to an escape of the intended path restriction.

The get_token() method of the salt.tokens.localfs class (which is exposed to unauthenticated requests by the ClearFuncs class) fails to sanitize the token input parameter which is then used as a filename, allowing insertion of ".." path elements and thus reading of files outside of the intended directory. The only restriction is that the file has to be deserializable by salt.payload.Serial.loads().

Typo3 News:

CVE-2020-11063: TYPO3-CORE-SA-2020-001: Information Disclosure in Password Reset

It has been discovered that time-based attacks can be used with the password reset functionality for backend users. This allows an attacker to verify whether a backend user account with a given email address exists or not.

CVE-2020-11064: TYPO3-CORE-SA-2020-002: Cross-Site Scripting in Form Engine

It has been discovered that HTML placeholder attributes containing data of other database records are vulnerable to cross-site scripting. A valid backend user account is needed to exploit this vulnerability.

CVE-2020-11065: TYPO3-CORE-SA-2020-003: Cross-Site Scripting in Link Handling

It has been discovered that link tags generated by typolink functionality are vulnerable to cross-site scripting - properties being assigned as HTML attributes have not been parsed correctly.

CVE-2020-11066: TYPO3-CORE-SA-2020-004: Class destructors causing side-effects when being unserialized

Calling unserialize() on malicious user-submitted content can result in the following scenarios:

- trigger deletion of arbitrary directory in file system (if writable for web server)

- trigger message submission via email using identity of web site (mail relay)

Another insecure deserialization vulnerability is required to actually exploit mentioned aspects.

CVE-2020-11067: TYPO3-CORE-SA-2020-005: Insecure Deserialization in Backend User Settings

It has been discovered that backend user settings (in $BE_USER->uc) are vulnerable to insecure deserialization. In combination with vulnerabilities of 3rd party components this can lead to remote code execution. A valid backend user account is needed to exploit this vulnerability.

CVE-2020-11069: TYPO3-CORE-SA-2020-006: Same-Site Request Forgery to Backend User Interface

It has been discovered that the backend user interface and install tool are vulnerable to same-site request forgery. A backend user can be tricked into interacting with a malicious resource an attacker previously managed to upload to the web server - scripts are then executed with the privileges of the victims’ user session.

In a worst case scenario new admin users can be created which can directly be used by an attacker. The vulnerability is basically a cross-site request forgery (CSRF) triggered by a cross-site scripting vulnerability (XSS) - but happens on the same target host - thus, it’ actually a same-site request forgery (SSRF).

Malicious payload such as HTML containing JavaScript might be provided by either an authenticated backend user or by a non-authenticated user using a 3rd party extension - e.g. file upload in a contact form with knowing the target location.

The attacked victim requires an active and valid backend or install tool user session at the time of the attack to be successful.

FreeBSD -- Insufficient cryptodev MAC key length check FreeBSD-kernel 12.112.1_5

Problem Description:

Requests to create cryptography sessions using a MAC did not validate the user-supplied MAC key length. The cryptodev module allocates a buffer whose size is this user-suppled length.

Impact:

An unprivileged process can trigger a kernel panic.

CVE-2019-15879 SA-20:15.cryptodev 2020-01-20 2020-05-12
FreeBSD -- Use after free in cryptodev module FreeBSD-kernel 12.112.1_5 11.311.3_9

Problem Description:

A race condition permitted a data structure in the kernel to be used after it was freed by the cryptodev module.

Impact:

An unprivileged process can overwrite arbitrary kernel memory.

CVE-2019-15879 SA-20:15.cryptodev 2020-01-20 2020-05-12
FreeBSD -- Improper checking in SCTP-AUTH shared key update FreeBSD-kernel 11.311.3_9

Problem Description:

The SCTP layer does improper checking when an application tries to update a shared key. Therefore an unprivileged local user can trigger a use-after- free situation, for example by specific sequences of updating shared keys and closing the SCTP association.

Impact:

Triggering the use-after-free situation may result in unintended kernel behaviour including a kernel panic.

CVE-2019-15878 SA-20:14.sctp 2019-09-19 2020-05-12
FreeBSD -- Memory disclosure vulnerability in libalias FreeBSD-kernel 12.112.1_5 11.411.4_1 11.311.3_9

Problem Description:

The FTP packet handler in libalias incorrectly calculates some packet lengths. This may result in disclosing small amounts of memory from the kernel (for the in-kernel NAT implementation) or from the process space for natd (for the userspace implementation).

Impact:

A malicious attacker could send specially constructed packets that exploit the erroneous calculation allowing the attacker to disclose small amount of memory either from the kernel (for the in-kernel NAT implementation) or from the process space for natd (for the userspace implementation).

CVE-2020-7455 SA-20:13.libalias 2020-05-12 2020-05-12
FreeBSD -- Insufficient packet length validation in libalias FreeBSD-kernel 12.112.1_5 11.411.4_1 11.311.3_9

Problem Description:

libalias(3) packet handlers do not properly validate the packet length before accessing the protocol headers. As a result, if a libalias(3) module does not properly validate the packet length before accessing the protocol header, it is possible for an out of bound read or write condition to occur.

Impact:

A malicious attacker could send specially constructed packets that exploit the lack of validation allowing the attacker to read or write memory either from the kernel (for the in-kernel NAT implementation) or from the process space for natd (for the userspace implementation).

qutebrowser -- Reloading page with certificate errors shows a green URL qutebrowser 1.11.1

Qutebrowser developers report:

After a certificate error was overridden by the user, qutebrowser displays the URL as yellow (colors.statusbar.url.warn.fg). However, when the affected website was subsequently loaded again, the URL was mistakenly displayed as green (colors.statusbar.url.success_https). While the user already has seen a certificate error prompt at this point (or set content.ssl_strict to false which is not recommended), this could still provide a false sense of security.

Wagtail -- potential timing attack vulnerability py35-wagtail py36-wagtail py37-wagtail py38-wagtail 2.7.3 2.82.8.2

Wagtail release notes:

CVE-2020-11037: Potential timing attack on password-protected private pages

This release addresses a potential timing attack on pages or documents that have been protected with a shared password through Wagtail's "Privacy" controls. This password check is performed through a character-by-character string comparison, and so an attacker who is able to measure the time taken by this check to a high degree of accuracy could potentially use timing differences to gain knowledge of the password. (This is understood to be feasible on a local network, but not on the public internet.)

Mark Sapiro reports:

A content injection vulnerability via the options login page has been discovered and reported by Vishal Singh.

An issue similar to CVE-2018-13796 exists at different endpoint & param. It can lead to a phishing attack.

(added 2020-05-07) This is essentially the same as https://bugs.launchpad.net/mailman/+bug/1873722 except the vector is the private archive login page and the attack only succeeds if the list's roster visibility (private_roster) setting is 'Anyone'.

vlc -- Multiple vulnerabilities fixed in VLC media player vlc 3.0.10,4

VideoLAN reports:

Details

A remote user could:

  • Create a specifically crafted image file that could trigger an out of bounds read
  • Send a specifically crafter request to the microdns service discovery, potentially triggering various memory management issues

Impact

If successful, a malicious third party could trigger either a crash of VLC or an arbitratry code execution with the privileges of the target user.

While these issues in themselves are most likely to just crash the player, we can't exclude that they could be combined to leak user informations or remotely execute code. ASLR and DEP help reduce the likelyness of code execution, but may be bypassed.

We have not seen exploits performing code execution through these vulnerabilities

CVE-2019-19721 affects VLC 3.0.8 and earlier, and only reads 1 byte out of bound

py-yaml -- FullLoader (still) exploitable for arbitrary command execution py27-yaml py35-yaml py36-yaml py37-yaml py38-yaml 5.3.1

Riccardo Schirone (https://github.com/ret2libc) reports:

In FullLoader python/object/new constructor, implemented by construct_python_object_apply, has support for setting the state of a deserialized instance through the set_python_instance_state method. After setting the state, some operations are performed on the instance to complete its initialization, however it is possible for an attacker to set the instance' state in such a way that arbitrary code is executed by the FullLoader.

This patch tries to block such attacks in FullLoader by preventing set_python_instance_state from setting arbitrar properties. It implements a blacklist that includes extend method (called by construct_python_object_apply) and all special methods (e.g. __set__, __setitem__, etc.).

Users who need special attributes being set in the state of a deserialized object can still do it through the UnsafeLoader, which however should not be used on untrusted input. Additionally, they can subclass FullLoader and redefine state_blacklist_regexp to include the additional attributes they need, passing the subclassed loader to yaml.load.

drupal -- Drupal Core - Moderately critical - Third-party library drupal8 8.8.4

Drupal Security Team reports:

The Drupal project uses the third-party library CKEditor, which has released a security improvement that is needed to protect some Drupal configurations.

Vulnerabilities are possible if Drupal is configured to use the WYSIWYG CKEditor for your site's users. An attacker that can createor edit content may be able to exploit this Cross Site Scripting (XSS) vulnerability to target users with access to the WYSIWYG CKEditor, and this may include site admins with privileged access.

The latest versions of Drupal update CKEditor to 4.14 to mitigate the vulnerabilities.

Borja Tarraso reports:

A flaw was found in Ansible Engine when using Ansible Vault for editing encrypted files. When a user executes "ansible-vault edit", another user on the same computer can read the old and new secret, as it is created in a temporary file with mkstemp and the returned file descriptor is closed and the method write_data is called to write the existing secret in the file. This method will delete the file before recreating it insecurely. All versions in 2.7.x, 2.8.x and 2.9.x branches are believed to be vulnerable.

openvpn -- illegal client float can break VPN session for other users openvpn 2.4.8_3 openvpn-mbedtls 2.4.8_3 openvpn-devel 202016

Lev Stipakov and Gert Doering report:

There is a time frame between allocating peer-id and initializing data channel key (which is performed on receiving push request or on async push-reply) in which the existing peer-id float checks do not work right.

If a "rogue" data channel packet arrives during that time frame from another address and with same peer-id, this would cause client to float to that new address.

The net effect of this behaviour is that the VPN session for the "victim client" is broken. Since the "attacker client" does not have suitable keys, it can not inject or steal VPN traffic from the other session. The time window is small and it can not be used to attack a specific client's session, unless some other way is found to make it disconnect and reconnect first.

Versions Affected: 9.6 - 12

The ALTER ... DEPENDS ON EXTENSION sub-commands do not perform authorization checks, which can allow an unprivileged user to drop any function, procedure, materialized view, index, or trigger under certain conditions. This attack is possible if an administrator has installed an extension and an unprivileged user can CREATE, or an extension owner either executes DROP EXTENSION predictably or can be convinced to execute DROP EXTENSION.

rubygem-json -- Unsafe Objection Creation Vulnerability in JSON (Additional fix) rubygem-json 2.3.0

When parsing certain JSON documents, the json gem (including the one bundled with Ruby) can be coerced into creating arbitrary objects in the target system.

This is the same issue as CVE-2013-0269. The previous fix was incomplete, which addressed JSON.parse(user_input), but didn’t address some other styles of JSON parsing including JSON(user_input) and JSON.parse(user_input, nil).

See CVE-2013-0269 in detail. Note that the issue was exploitable to cause a Denial of Service by creating many garbage-uncollectable Symbol objects, but this kind of attack is no longer valid because Symbol objects are now garbage-collectable. However, creating arbitrary bjects may cause severe security consequences depending upon the application code.

Please update the json gem to version 2.3.0 or later. You can use gem update json to update it. If you are using bundler, please add gem "json", ">= 2.3.0" to your Gemfile.

puppetserver and puppetdb -- Puppet Server and PuppetDB may leak sensitive information via metrics API puppetdb5 5.2.13 puppetdb6 6.9.1 puppetserver5 5.3.12 puppetserver6 6.9.2

Puppetlabs reports:

Puppet Server and PuppetDB provide useful performance and debugging information via their metrics API endpoints. For PuppetDB this may contain things like hostnames. Puppet Server reports resource names and titles for defined types (which may contain sensitive information) as well as function names and class names. Previously, these endpoints were open to the local network.

PE 2018.1.13 & 2019.4.0, Puppet Server 6.9.1 & 5.3.12, and PuppetDB 6.9.1 & 5.2.13 disable trapperkeeper-metrics /v1 metrics API and only allows /v2 access on localhost by default.

puppet6 -- Arbitrary Catalog Retrieval puppet6 6.13.0

Puppetlabs reports:

Previously, Puppet operated on a model that a node with a valid certificate was entitled to all information in the system and that a compromised certificate allowed access to everything in the infrastructure. When a node's catalog falls back to the `default` node, the catalog can be retrieved for a different node by modifying facts for the Puppet run. This issue can be mitigated by setting `strict_hostname_checking = true` in `puppet.conf` on your Puppet master.

Puppet 6.13.0 changes the default behavior for strict_hostname_checking from false to true. It is recommended that Puppet Open Source and Puppet Enterprise users that are not upgrading still set strict_hostname_checking to true to ensure secure behavior.

FreeBSD -- Kernel memory disclosure with nested jails FreeBSD-kernel 12.112.1_3 11.311.3_7

Problem Description:

A missing NUL-termination check for the jail_set(2) configration option "osrelease" may return more bytes when reading the jail configuration back with jail_get(2) than were originally set.

Impact:

For jails with a non-default setting of children.max > 0 ("nested jails") a superuser inside a jail can create a jail and may be able to read and take advantage of exposed kernel memory.

CVE-2020-7453 SA-20:08.jail 2020-03-19 2020-03-19
FreeBSD -- Incorrect user-controlled pointer use in epair FreeBSD-kernel 12.112.1_3 11.311.3_7

Problem Description:

Incorrect use of a potentially user-controlled pointer in the kernel allowed vnet jailed users to panic the system and potentially execute aribitrary code in the kernel.

Impact:

Users with root level access (or the PRIV_NET_IFCREATE privilege) can panic the system, or potentially escape the jail or execute arbitrary code with kernel priviliges.

FreeBSD -- Insufficient ixl(4) ioctl(2) privilege checking FreeBSD-kernel 12.112.1_3

Problem Description:

The driver-specific ioctl(2) command handlers in ixl(4) failed to check whether the caller has sufficient privileges to perform the corresponding operation.

Impact:

The ixl(4) handler permits unprivileged users to trigger updates to the device's non-volatile memory (NVM).

CVE-2019-15877 SA-20:06.if_ixl_ioctl 2020-03-19 2020-03-19
FreeBSD -- Insufficient oce(4) ioctl(2) privilege checking FreeBSD-kernel 12.112.1_3 11.311.3_7

Problem Description:

The driver-specific ioctl(2) command handlers in oce(4) failed to check whether the caller has sufficient privileges to perform the corresponding operation.

Impact:

The oce(4) handler permits unprivileged users to send passthrough commands to device firmware.

CVE-2019-15876 SA-20:05.if_oce_ioctl 2020-03-19 2020-03-19
FreeBSD -- TCP IPv6 SYN cache kernel information disclosure FreeBSD-kernel 12.112.1_3 11.311.3_7

Problem Description:

When a TCP server transmits or retransmits a TCP SYN-ACK segment over IPv6, the Traffic Class field is not initialized. This also applies to challenge ACK segments, which are sent in response to received RST segments during the TCP connection setup phase.

Impact:

For each TCP SYN-ACK (or challenge TCP-ACK) segment sent over IPv6, one byte of kernel memory is transmitted over the network.

www/py-bleach -- multiple vulnerabilities py27-bleach py35-bleach py36-bleach py37-bleach py38-bleach 3.1.2

* ``bleach.clean`` behavior parsing embedded MathML and SVG content with RCDATA tags did not match browser behavior and could result in a mutation XSS.

Calls to ``bleach.clean`` with ``strip=False`` and ``math`` or ``svg`` tags and one or more of the RCDATA tags ``script``, ``noscript``, ``style``, ``noframes``, ``iframe``, ``noembed``, or ``xmp`` in the allowed tags whitelist were vulnerable to a mutation XSS.

* ``bleach.clean`` behavior parsing ``noscript`` tags did not match browser behavior.

Calls to ``bleach.clean`` allowing ``noscript`` and one or more of the raw text tags (``title``, ``textarea``, ``script``, ``style``, ``noembed``, ``noframes``, ``iframe``, and ``xmp``) were vulnerable to a mutation XSS.

zeek -- potential denial of service issues zeek 3.0.3

Jon Siwek of Corelight reports:

This release addresses the following security issues:

  • Potential Denial of Service due to memory leak in DNS TSIG message parsing.
  • Potential Denial of Service due to memory leak (or assertion when compiling with assertions enabled) when receiving a second SSH KEX message after a first.
  • Potential Denial of Service due to buffer read overflow and/or memory leaks in Kerberos analyzer. The buffer read overflow could occur when the Kerberos message indicates it contains an IPv6 address, but does not send enough data to parse out a full IPv6 address. A memory leak could occur when processing KRB_KDC_REQ KRB_KDC_REP messages for message types that do not match a known/expected type.
  • Potential Denial of Service when sending many zero-length SSL/TLS certificate data. Such messages underwent the full Zeek file analysis treatment which is expensive (and meaninguless here) compared to how cheaply one can "create" or otherwise indicate many zero-length contained in an SSL message.
  • Potential Denial of Service due to buffer read overflow in SMB transaction data string handling. The length of strings being parsed from SMB messages was trusted to be whatever the message claimed instead of the actual length of data found in the message.
  • Potential Denial of Service due to null pointer dereference in FTP ADAT Base64 decoding.
  • Potential Denial of Service due buffer read overflow in FTP analyzer word/whitespace handling. This typically won't be a problem in most default deployments of Zeek since the FTP analyzer receives data from a ContentLine (NVT) support analyzer which first null-terminates the buffer used for further FTP parsing.

Okular -- Local binary execution via action links okular 19.12.3_3

Albert Astals Cid:

Okular can be tricked into executing local binaries via specially crafted PDF files.

This binary execution can require almost no user interaction.

No parameters can be passed to those local binaries.

We have not been able to identify any binary that will cause actual damage, be it in the hardware or software level, when run without parameters.

We remain relatively confident that for this issue to do any actual damage, it has to run a binary specially crafted. That binary must have been deployed to the user system via another method, be it the user downloading it directly as an email attachment, webpage download, etc. or by the system being already compromised.

Node.js -- multiple vulnerabilities node 13.8.0 node12 12.15.0 node10 10.19.0

Node.js reports:

Updates are now available for all active Node.js release lines for the following issues.

HTTP request smuggling using malformed Transfer-Encoding header (Critical) (CVE-2019-15605)HTTP request smuggling using malformed Transfer-Encoding header (Critical) (CVE-2019-15605)

Affected Node.js versions can be exploited to perform HTTP desync attacks and deliver malicious payloads to unsuspecting users. The payloads can be crafted by an attacker to hijack user sessions, poison cookies, perform clickjacking, and a multitude of other attacks depending on the architecture of the underlying system.

HTTP header values do not have trailing OWS trimmed (High) (CVE-2019-15606)

Optional whitespace should be trimmed from HTTP header values. Its presence may allow attackers to bypass security checks based on HTTP header values.

Remotely trigger an assertion on a TLS server with a malformed certificate string (High) (CVE-2019-15604)

Connecting to a NodeJS TLS server with a client certificate that has a type 19 string in its subjectAltName will crash the TLS server if it tries to read the peer certificate.

Strict HTTP header parsing (None)

Increase the strictness of HTTP header parsing. There are no known vulnerabilities addressed, but lax HTTP parsing has historically been a source of problems. Some commonly used sites are known to generate invalid HTTP headers, a --insecure-http-parser CLI option or insecureHTTPParser http option can be used if necessary for interoperability, but is not recommended.

ntp -- Multiple vulnerabilities FreeBSD 11.311.3_7 12.112.1_3 ntp 4.2.8p14 ntp-devel 4.3.99_6

nwtime.org reports:

Three ntp vulnerabilities, Depending on configuration, may have little impact up to termination of the ntpd process.

NTP Bug 3610: Process_control() should exit earlier on short packets. On systems that override the default and enable ntpdc (mode 7) fuzz testing detected that a short packet will cause ntpd to read uninitialized data.

NTP Bug 3596: An unauthenticated unmonitored ntpd is vulnerable to attack on IPv4 with highly predictable transmit timestamps. An off-path attacker who can query time from the victim's ntp which receives time from an unauthenticated time source must be able to send from a spoofed IPv4 address of upstream ntp server and and the victim must be able to process a large number of packets with the spoofed IPv4 address of the upstream server. After eight or more successful attacks in a row the attacker can either modify the victim's clock by a small amount or cause ntpd to terminate. The attack is especially effective when unusually short poll intervals have been configured.

NTP Bug 3592: The fix for https://bugs.ntp.org/3445 introduced a bug such that a ntp can be prevented from initiating a time volley to its peer resulting in a DoS.

All three NTP bugs may result in DoS or terimation of the ntp daemon.

librsvg2 -- multiple vulnabilities librsvg2 2.40.21 librsvg2-rust 2.41.02.46.3

Librsvg2 developers reports:

Backport the following fixes from 2.46.x:

Librsvg now has limits on the number of loaded XML elements, and the number of referenced elements within an SVG document. This is to mitigate malicious SVGs which try to consume all memory, and those which try to consume an exponential amount of CPU time.

Fix stack exhaustion with circular references in <use> elements.

Fix a denial-of-service condition from exponential explosion of rendered elements, through nested use of SVG <use> elements in malicious SVGs. This is similar to the XML "billion laughs attack" but for SVG instancing.

OpenSMTPd -- LPE and RCE in OpenSMTPD's default install opensmtpd 6.6.4,1

OpenSMTPD developers reports:

An out of bounds read in smtpd allows an attacker to inject arbitrary commands into the envelope file which are then executed as root. Separately, missing privilege revocation in smtpctl allows arbitrary commands to be run with the _smtpq group.

An unprivileged local attacker can read the first line of an arbitrary file (for example, root's password hash in /etc/master.passwd) or the entire contents of another user's file (if this file and /var/spool/smtpd/ are on the same filesystem).

Mbed TLS -- Cache attack against RSA key import in SGX mbedtls 2.16.5

Janos Follath reports:

If Mbed TLS is running in an SGX enclave and the adversary has control of the main operating system, they can launch a side channel attack to recover the RSA private key when it is being imported.

The attack only requires access to fine grained measurements to cache usage. Therefore the attack might be applicable to a scenario where Mbed TLS is running in TrustZone secure world and the attacker controls the normal world or possibly when Mbed TLS is part of a hypervisor and the adversary has full control of a guest OS.

Mbed TLS -- Side channel attack on ECDSA mbedtls 2.16.4

Janos Follath reports:

Our bignum implementation is not constant time/constant trace, so side channel attacks can retrieve the blinded value, factor it (as it is smaller than RSA keys and not guaranteed to have only large prime factors), and then, by brute force, recover the key.

FreeBSD -- Missing IPsec anti-replay window check FreeBSD-kernel 12.012.0_13

Problem Description:

A missing check means that an attacker can reinject an old packet and it will be accepted and processed by the IPsec endpoint.

Impact:

The impact depends on the higher-level protocols in use over IPsec. For example, an attacker who can capture and inject packets could cause an action that was intentionally performed once to be repeated.

FreeBSD -- libfetch buffer overflow FreeBSD 12.112.1_2 12.012.0_13 11.311.3_6

Problem Description:

A programming error allows an attacker who can specify a URL with a username and/or password components to overflow libfetch(3) buffers.

Impact:

An attacker in control of the URL to be fetched (possibly via HTTP redirect) may cause a heap buffer overflow, resulting in program misbehavior or malicious code execution.

grub2-bhyve -- multiple privilege escalations grub2-bhyve 0.40_8

Reno Robert reports:

FreeBSD uses a two-process model for running a VM. For booting non-FreeBSD guests, a modified grub-emu is used (grub-bhyve). Grub-bhyve executes command from guest grub.cfg file. This is a security problem because grub was never written to handle inputs from OS as untrusted. In the current design, grub and guest OS works across trust boundaries. This exposes a grub to untrusted inputs from guest.

grub-bhyve (emu) is built without SDL graphics support which reduces lot of gfx attack surface, however font loading code is still accessible. Guest can provide arbitrary font file, which is parsed by grub-bhyve running as root.

In grub-core/font/font.c, read_section_as_string() allocates section->length + 1 bytes of memory. However, untrusted section->length is an unsigned 32-bit number, and the result can overflow to malloc(0). This can result in a controlled buffer overflow via the 'loadfont' command in a guest VM grub2.cfg, eventually leading to privilege escalation from guest to host.

Reno Robert also reports:

GRUB supports commands to read and write addresses of choice. In grub-bhyve, these commands provide a way to write to arbitrary virtual addresses within the grub-bhyve process. This is another way for a guest grub2.cfg, run by the host, to eventually escalate privileges.

These vulnerabilities are mitigated by disabling the 'loadfont', 'write_dword', 'read_dword', 'inl', 'outl', and other width variants of the same functionality in grub2-bhyve.

There is also work in progress to sandbox the grub-bhyve utility such that an escaped guest ends up with nobody:nobody in a Capsium sandbox. It is not included in 0.40_8.

MITRE CVE reports:

Django 1.11 before 1.11.28, 2.2 before 2.2.10, and 3.0 before 3.0.3 allows SQL Injection if untrusted data is used as a StringAgg delimiter (e.g., in Django applications that offer downloads of data as a series of rows with a user-specified column delimiter). By passing a suitably crafted delimiter to a contrib.postgres.aggregates.StringAgg instance, it was possible to break escaping and inject malicious SQL.

libssh -- Unsanitized location in scp could lead to unwanted command execution libssh 0.4.00.8.8 0.9.00.9.3

The libssh team reports:

In an environment where a user is only allowed to copy files and not to execute applications, it would be possible to pass a location which contains commands to be executed in additon.

When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of ssh_scp_new(), it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target.

The Apache SpamAssassin project reports:

A nefarious rule configuration (.cf) files can be configured to run system commands. This issue is less stealthy and attempts to exploit the issue will throw warnings.

Thanks to Damian Lukowski at credativ for reporting the issue ethically. With this bug unpatched, exploits can be injected in a number of scenarios though doing so remotely is difficult.

sudo -- Potential bypass of Runas user restrictions sudo 1.8.31

Todd C. Miller reports:

Sudo's pwfeedback option can be used to provide visual feedback when the user is inputting their password. For each key press, an asterisk is printed. This option was added in response to user confusion over how the standard Password: prompt disables the echoing of key presses. While pwfeedback is not enabled by default in the upstream version of sudo, some systems, such as Linux Mint and Elementary OS, do enable it in their default sudoers files.

Due to a bug, when the pwfeedback option is enabled in the sudoers file, a user may be able to trigger a stack-based buffer overflow. This bug can be triggered even by users not listed in the sudoers file. There is no impact unless pwfeedback has been enabled.

Pillow -- Multiple vulnerabilities py27-pillow py35-pillow py36-pillow py37-pillow py38-pillow 6.2.2

Pillow developers report:

This release addresses several security problems, as well as addressing CVE-2019-19911.

CVE-2019-19911 is regarding FPX images. If an image reports that it has a large number of bands, a large amount of resources will be used when trying to process the image. This is fixed by limiting the number of bands to those usable by Pillow.

Intel reports:

.A potential security vulnerability in Intel(R) Processor Graphics may allow information disclosure. Intel is releasing software updates to mitigate this potential vulnerability.

Description: Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may allow an unauthenticated user to potentially enable information disclosure via local access.

This patch provides mitigation for Gen9 hardware only. Patches for Gen7 and Gen7.5 will be provided later. Note that Gen8 is not impacted due to a previously implemented workaround. The mitigation involves using an existing hardware feature to forcibly clear down all EU state at each context switch.

Template::Toolkit -- Directory traversal on write p5-Template-Toolkit 3.004

Art Manion and Will Dormann report:

By using an older and less-secure form of open(), it is possible for untrusted template files to cause reads/writes outside of the template directories. This vulnerability is a component of the recent Citrix exploit.

e2fsprogs -- rehash.c/pass 3a mutate_name() code execution vulnerability e2fsprogs 1.45.5

Lilith of Cisco Talos reports:

A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4. A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.

Theodore Y. Ts'o reports:

E2fsprogs 1.45.5 [...:] Fix a potential out of bounds write when checking a maliciously corrupted file system. This is probably not exploitable on 64-bit platforms, but may be exploitable on 32-bit binaries depending on how the compiler lays out the stack variables. (Addresses CVE-2019-5188)

The cacti developers reports:

When viewing graphs, some input variables are not properly checked (SQL injection possible).

Multiple instances of lib/functions.php are affected by unsafe deserialization of user-controlled data to populate arrays. An authenticated attacker could use this to influence object data values and control actions taken by Cacti or potentially cause memory corruption in the PHP module.
