ClamAV: Multiple issues ClamAV contains two vulnerabilities that could lead to Denial of Service and evasion of virus scanning. clamav January 31, 2005 May 22, 2006: 02 78656 79194 remote 0.81 0.80

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

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

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.

There is no known workaround at this time.

All ClamAV users should upgrade to the latest version:
