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 < 0.94 >= 0.94 Description =========== Hanno boeck reported an error in libclamav/chmunpack.c when processing CHM files (CVE-2008-1389). Other unspecified vulnerabilites were also reported, including a NULL pointer dereference in libclamav (CVE-2008-3912), memory leaks in freshclam/manager.c (CVE-2008-3913), and file descriptor leaks in libclamav/others.c and libclamav/sis.c (CVE-2008-3914). Impact ====== A remote attacker could entice a user or automated system to scan a specially crafted CHM, possibly resulting in a Denial of Service (daemon crash). The other attack vectors mentioned above could also result in a Denial of Service. 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-0.94" References ========== [ 1 ] CVE-2008-1389 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1389 [ 2 ] CVE-2008-3912 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3912 [ 3 ] CVE-2008-3913 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3913 [ 4 ] CVE-2008-3914 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3914 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200809-18.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.
