Synopsis ========
Multiple vulnerabilities in ClamAV may result in a Denial of Service.
Background ==========
Clam AntiVirus is a free anti-virus toolkit for UNIX, designed especially for e-mail scanning on mail gateways.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-antivirus/clamav < 0.93.3 >= 0.93.3
Description ===========
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.
Impact ======
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.
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-0.93.3"
