Background ========== xine-lib is a multimedia library which can be utilized to create multimedia frontends. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/xine-lib < 1.0-r2 >= 1.0-r2 *>= 1_rc6-r2 Description =========== Heap overflows have been found in the code handling RealMedia RTSP and Microsoft Media Services streams over TCP (MMST). Impact ====== By setting up a malicious server and enticing a user to use its streaming data, a remote attacker could possibly execute arbitrary code on the client computer with the permissions of the user running any multimedia frontend making use of the xine-lib library. 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 ] Xine Advisory XSA-2004-8 http://xinehq.de/index.php/security/XSA-2004-8 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200504-27.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.
