Background - -Samba is an implementation of the Server Message Block (SMB) -protocol. - -II. Problem Description - -The samba ports, versions prior to samba-2.0.8 and samba-devel-2.2.0, -contain /tmp races that may allow local users to cause arbitrary -files and devices to be overwritten. Due to easily predictable -printer queue cache file names, local users may create symbolic links -to any file or device causing it to be corrupted when a remote user -accesses a printer. In addition, the file will be left with world- -writable permission allowing any user to enter their own data. - -The samba ports are not installed by default, nor are they "part of -FreeBSD" as such: they are part of the FreeBSD ports collection, which -contains over 5000 third-party applications in a ready-to-install -format. The ports collections shipped with FreeBSD 3.5.1 and 4.2 -contain this problem since it was discovered after the releases. -The ports collection that shipped with FreeBSD 4.3 is not vulnerable -since this problem was corrected prior to the release. - -FreeBSD makes no claim about the security of these third-party -applications, although an effort is underway to provide a security -audit of the most security-critical ports. - -III. Impact - -Unprivileged local users may cause arbitrary files or devices to be -corrupted and gain increased privileges on the local system. - -If you have not chosen to install the samba ports/packages, then -your system is not vulnerable to this problem. - -Samba servers that do not have any printers configured are not -vulnerable. - -IV. Workaround - -Deinstall the samba port/package, if you have installed it. - -V. Solution - -One of the following: - -1) Upgrade your entire ports collection and rebuild the samba port. - -2) Deinstall the old package and install a new package dated after the -correction date, obtained from: - -[i386] -ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/net/samba-2.0.8.tgz -ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/net/samba-2.0.8.tgz -ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/net/samba-devel-2.2.0.tgz -ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/net/samba-devel-2.2.0.tgz - -NOTE: it may be several days before updated packages are available. - -[alpha] -Packages are not automatically generated for the alpha architecture at -this time due to lack of build resources. - -3) download a new port skeleton for the samba from: - -http://www.freebsd.org/ports/ - -and use it to rebuild the port. - -4) Use the portcheckout utility to automate option (3) above.
