Background ========== ClamAV is an antivirus toolkit. It includes a multi-threaded daemon and a command line scanner. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-antivirus/clamav <= 0.80 >= 0.81 Description =========== ClamAV fails to properly scan ZIP files with special headers (CAN-2005-0133) and base64 encoded images in URLs. Impact ====== 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. 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-0.81" References ========== [ 1 ] CAN-2005-0133 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0133 [ 2 ] ClamAV Release Announcement http://sourceforge.net/forum/forum.php?forum_id=440649 [ 3 ] Secunia SA13900 http://secunia.com/advisories/13900/ Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200501-46.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.
