Synopsis
=======
ClamAV contains two vulnerabilities that could lead to Denial of
Service and evasion of virus scanning.

Background
=========
ClamAV is an antivirus toolkit. It includes a multi-threaded daemon and
a command line scanner.

Affected packages
================
    -------------------------------------------------------------------
     Package               /  Vulnerable  /                 Unaffected
    -------------------------------------------------------------------
  1  app-antivirus/clamav       <= 0.80                        >= 0.81

Description
==========
ClamAV fails to properly scan ZIP files with special headers(CAN-2005-0133) and base64 encoded images in URLs.

Impact
=====
By sending a base64 encoded image file in a URL an attacker could evade
virus scanning. By sending a specially-crafted ZIP file an attacker
could cause a Denial of Service by crashing the clamd daemon.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All ClamAV users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.81"
