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" References ========== [ 1 ] CVE-2007-6595 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6595 [ 2 ] CVE-2008-2713 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-2713 [ 3 ] CVE-2008-3215 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3215 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200808-07.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
