Background ========== ClamAV is a GPL virus scanner. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-antivirus/clamav < 0.88.4 >= 0.88.4 Description =========== Damian Put has discovered a boundary error in the pefromupx() function used by the UPX extraction module, which unpacks PE Windows executable files. Both the "clamscan" command-line utility and the "clamd" daemon are affected. Impact ====== By sending a malicious attachment to a mail server running ClamAV, a remote attacker can cause a Denial of Service and potentially the execution of arbitrary code with the permissions of the user running ClamAV. 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-0.88.4" References ========== [ 1 ] ClamAV security advisory http://www.clamav.net/security/0.88.4.html Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200608-13.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.
