Background ========== Clam AntiVirus is a GPL anti-virus toolkit, designed for integration with mail servers to perform attachment scanning. Clam AntiVirus also provides a command line scanner and a tool for fetching updates of the virus database. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-antivirus/clamav < 0.86.2 >= 0.86.2 Description =========== Neel Mehta and Alex Wheeler discovered that Clam AntiVirus is vulnerable to integer overflows when handling the TNEF, CHM and FSG file formats. Impact ====== By sending a specially-crafted file an attacker could execute arbitrary code with the permissions of the user running Clam AntiVirus. Workaround ========== There is no known workaround at this time. Resolution ========== All Clam AntiVirus users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.86.2" References ========== [ 1 ] BugTraq Announcement http://www.securityfocus.com/archive/1/406377/30/ [ 2 ] Clam AntiVirus: Release Notes http://sourceforge.net/project/shownotes.php?release_id=344514 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200507-25.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.
