Background ========== RAR is a powerful archive manager that can decompress RAR, ZIP and other files, and can create new archives in RAR and ZIP file format. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-arch/rar < 3.5.1 >= 3.5.1 Description =========== Tan Chew Keong reported about two vulnerabilities found in RAR: * A format string error exists when displaying a diagnostic error message that informs the user of an invalid filename in an UUE/XXE encoded file. * Some boundary errors in the processing of malicious ACE archives can be exploited to cause a buffer overflow. Impact ====== A remote attacker could exploit these vulnerabilities by enticing a user to: * decode a specially crafted UUE/XXE file, or * extract a malicious ACE archive containing a file with an overly long filename. When the user performs these actions, the arbitrary code of the attacker's choice will be executed. Workaround ========== There is no known workaround at this time. Resolution ========== All RAR users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-arch/rar-3.5.1" References ========== [ 1 ] RAR Release Notes http://www.rarlabs.com/rarnew.htm [ 2 ] Secunia Research 11/10/2005 http://secunia.com/secunia_research/2005-53/advisory/ Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200511-10.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.
