Background ========== ClamAV is a GPL anti-virus toolkit, designed for integration with mail servers to perform attachment scanning. ClamAV 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 < 0.87.1 >= 0.87.1 Description =========== ClamAV has multiple security flaws: a boundary check was performed incorrectly in petite.c, a buffer size calculation in unfsg_133 was incorrect in fsg.c, a possible infinite loop was fixed in tnef.c and a possible infinite loop in cabd_find was fixed in cabd.c . In addition to this, Marcin Owsiany reported that a corrupted DOC file causes a segmentation fault in ClamAV. Impact ====== By sending a malicious attachment to a mail server that is hooked with ClamAV, a remote attacker could cause a Denial of Service or the execution of arbitrary code. 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-0.87.1" References ========== [ 1 ] CAN-2005-3239 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3239 [ 2 ] CAN-2005-3303 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3303 [ 3 ] ClamAV release notes http://sourceforge.net/project/shownotes.php?release_id=368319 [ 4 ] Zero Day Initiative advisory http://www.zerodayinitiative.com/advisories/ZDI-05-002.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200511-04.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.
