Background - -FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is -a collaborative effort to develop a robust, commercial-grade, full-featured -Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) -and Transport Layer Security (TLS v1) protocols as well as a full-strength -general purpose cryptography library. - -II. Problem Description - -The signature verification routines will crash with a NULL pointer dereference -if presented with an ASN.1 signature using the RSA PSS algorithm and absent -mask generation function parameter. [CVE-2015-3194] - -When presented with a malformed X509_ATTRIBUTE structure, OpenSSL will leak -memory. [CVE-2015-3195] - -If PSK identity hints are received by a multi-threaded client then the values -are incorrectly updated in the parent SSL_CTX structure. [CVE-2015-3196] - -III. Impact - -A remote attacker who can present a specifically crafted certificate may -cause a OpenSSL client or server application that performs certificate -signature verification to crash with a NULL pointer dereference, resulting -in a Denial of Service. [CVE-2015-3194] This affects FreeBSD 10.x only. - -An attacker who is able to feed specifically crafted PKCS#7/CMS data to an -OpenSSL application can cause memory leak which may eventually result in a -Denial of Service. [CVE-2015-3195] - -A remote attacker who can send PSK identity hints to a multi-thread client -may trigger a double fault of hint data, which may lead to crash the client -application. [CVE-2015-3196]. This affects FreeBSD 10.1 only. - -IV. Workaround - -No workaround is available. - -V. Solution - -Perform one of the following: - -1) Upgrade your vulnerable system to a supported FreeBSD stable or -release / security branch (releng) dated after the correction date. - -Reboot is optional but recommended. - -2) To update your vulnerable system via a binary patch: - -Systems running a RELEASE version of FreeBSD on the i386 or amd64 -platforms can be updated via the freebsd-update(8) utility: - -# freebsd-update fetch -# freebsd-update install - -Reboot is optional but recommended. - -3) To update your vulnerable system via a source code patch: - -The following patches have been verified to apply to the applicable -FreeBSD release branches. - -a) Download the relevant patch from the location below, and verify the -detached PGP signature using your PGP utility. - -[FreeBSD 9.3] -# fetch https://security.FreeBSD.org/patches/SA-15:26/openssl-9.3.patch -# fetch https://security.FreeBSD.org/patches/SA-15:26/openssl-9.3.patch.asc -# gpg --verify openssl-9.3.patch.asc - -[FreeBSD 10.1] -# fetch https://security.FreeBSD.org/patches/SA-15:26/openssl-10.1.patch -# fetch https://security.FreeBSD.org/patches/SA-15:26/openssl-10.1.patch.asc -# gpg --verify openssl-10.1.patch.asc - -[FreeBSD 10.2] -# fetch https://security.FreeBSD.org/patches/SA-15:26/openssl-10.2.patch -# fetch https://security.FreeBSD.org/patches/SA-15:26/openssl-10.2.patch.asc -# gpg --verify openssl-10.2.patch.asc - -b) Apply the patch.
