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
