ClamAV: Multiple Denials of Service

ClamAV: Multiple Denials of Service Multiple vulnerabilities in ClamAV may result in a Denial of Service. clamav 2008-08-08 2008-08-08 204340 227351 remote 0.93.3 0.93.3

Clam AntiVirus is a free anti-virus toolkit for UNIX, designed especially for e-mail scanning on mail gateways.

Damian Put has discovered an out-of-bounds memory access while processing Petite files (CVE-2008-2713, CVE-2008-3215). Also, please note that the 0.93 ClamAV branch fixes the first of the two attack vectors of CVE-2007-6595 concerning an insecure creation of temporary files vulnerability. The sigtool attack vector seems still unfixed.

A remote attacker could entice a user or automated system to scan a specially crafted Petite file, possibly resulting in a Denial of Service (daemon crash). Also, the insecure creation of temporary files vulnerability can be triggered by a local user to perform a symlink attack.

There is no known workaround at this time.

All ClamAV users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.93.3"
