Background ========== Clam AntiVirus (short: ClamAV) is an anti-virus toolkit for UNIX, designed especially for e-mail scanning on mail gateways. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-antivirus/clamav < 0.95.2 >= 0.95.2 Description =========== Multiple vulnerabilities have been found in ClamAV: * The vendor reported a Divide-by-zero error in the PE ("Portable Executable"; Windows .exe) file handling of ClamAV (CVE-2008-6680). * Jeffrey Thomas Peckham found a flaw in libclamav/untar.c, possibly resulting in an infinite loop when processing TAR archives in clamd and clamscan (CVE-2009-1270). * Martin Olsen reported a vulnerability in the CLI_ISCONTAINED macro in libclamav/others.h, when processing UPack archives (CVE-2009-1371). * Nigel disclosed a stack-based buffer overflow in the "cli_url_canon()" function in libclamav/phishcheck.c when processing URLs (CVE-2009-1372). Impact ====== A remote attacker could entice a user or automated system to process a specially crafted UPack archive or a file containing a specially crafted URL, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application, or a Denial of Service. Furthermore, a remote attacker could cause a Denial of Service by supplying a specially crafted TAR archive or PE executable to a Clam AntiVirus instance. Workaround ========== There is no known workaround at this time. Resolution ========== All Clam AntiVirus users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose =app-antivirus/clamav-0.95.2 References ========== [ 1 ] CVE-2008-6680 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-6680 [ 2 ] CVE-2009-1270 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1270 [ 3 ] CVE-2009-1371 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1371 [ 4 ] CVE-2009-1372 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1372 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200909-04.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.
