All supported architectures
Multiple vulnerabilities in ClamAV may result in a Denial of Service.
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
There is no known workaround at this time.
All ClamAV users should upgrade to the latest version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.93.3"
