Background ========== ClamAV is a GPL virus scanner. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-antivirus/clamav < 0.88 >= 0.88 Description =========== Zero Day Initiative (ZDI) reported a heap buffer overflow vulnerability. The vulnerability is due to an incorrect boundary check of the user-supplied data prior to copying it to an insufficiently sized memory buffer. The flaw occurs when the application attempts to handle compressed UPX files. Impact ====== For example by sending a maliciously crafted UPX file into a mail server that is integrated with ClamAV, a remote attacker's supplied code could be executed with escalated privileges. 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" References ========== [ 1 ] CVE-2006-0162 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0162 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200601-07.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.
