Background ========== w3m is a multi-platform text-based web browser. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-client/w3m < 0.5.1-r4 >= 0.5.1-r4 Description =========== w3m in -dump or -backend mode does not correctly handle printf() format string specifiers in the Common Name (CN) field of an X.509 SSL certificate. Impact ====== An attacker could entice a user to visit a malicious website that would load a specially crafted X.509 SSL certificate containing "%n" or other format string specifiers, possibly resulting in the execution of arbitrary code with the rights of the user running w3m. Workaround ========== There is no known workaround at this time. Resolution ========== All w3m users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-client/w3m-0.5.1-r4" References ========== [ 1 ] CVE-2006-6772 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-6772 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200701-06.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.
