Background ========= From http://www.clamav.net/ : "Clam AntiVirus is a GPL anti-virus toolkit for UNIX. The main purpose of this software is the integration with mail servers (attachment scanning). The package provides a flexible and scalable multi-threaded daemon, a command line scanner, and a tool for automatic updating via Internet. The programs are based on a shared library distributed with the Clam AntiVirus package, which you can use with your own software. Most importantly, the virus database is kept up to date." Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- net-mail/clamav = 0.68.1 Description ========== Certain types of RAR archives, including those created by variants of the W32.Beagle.A@mm worm, may cause clamav to crash when it attempts to process them. Impact ===== This vulnerability causes a Denial of Service in the clamav process. Depending on configuration, this may cause dependent services such as mail to fail as well. Workaround ========= A workaround is not currently known for this issue. Allusers are advised to upgrade to the latest version of the affected package. Resolution ========= ClamAV users should upgrade to version 0.68.1 or later: # emerge sync # emerge -pv "> =net-mail/clamav-0.68.1" # emerge "> =net-mail/clamav-0.68.1" Concerns? ======== Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
