Background ========== xine-lib is a multimedia library which can be utilized to create multimedia frontends. It includes functions to retrieve information about audio CD contents from public CDDB servers. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/xine-lib < 1.1.0-r5 >= 1.1.0-r5 *>= 1.0.1-r4 *>= 1_rc8-r2 Description =========== Ulf Harnhammar discovered a format string bug in the routines handling CDDB server response contents. Impact ====== An attacker could submit malicious information about an audio CD to a public CDDB server (or impersonate a public CDDB server). When the victim plays this CD on a multimedia frontend relying on xine-lib, it could end up executing arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All xine-lib users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose media-libs/xine-lib References ========== [ 1 ] CAN-2005-2967 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2967 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200510-08.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.
