Synopsis
========
ClamAV is vulnerable to a denial of service attack when processing certain RAR archives.
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 >= 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. All users 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. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
