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"
