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 < 0.91.2-r1 >= 0.91.2-r1 Description =========== iDefense reported an integer overflow vulnerability in the cli_scanpe() function when parsing Portable Executable (PE) files packed in the MEW format, that could be exploited to cause a heap-based buffer overflow (CVE-2007-6335). Toeroek Edwin reported an off-by-one error when decompressing MS-ZIP compressed CAB files (CVE-2007-6336). An unspecified vulnerability related to the bzip2 decompression algorithm has also been discovered (CVE-2007-6337). Impact ====== A remote attacker could entice a user or automated system to scan a specially crafted file, possibly leading to the execution of arbitrary code with the privileges of the user running ClamAV (either a system user or the "clamav" user if clamd is compromised). Workaround ========== There is no known workaround at this time. Resolution ========== All ClamAV users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot -v ">=app-antivirus/clamav-0.91.2-r1" References ========== [ 1 ] CVE-2007-6335 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6335 [ 2 ] CVE-2007-6336 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6336 [ 3 ] CVE-2007-6337 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-6337 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200712-20.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.
