Background ========== Kaffeine and gxine are graphical front-ends for xine-lib multimedia library. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-video/kaffeine < 0.5_rc1-r1 >= 0.5_rc1-r1 *>= 0.4.3b-r1 2 media-video/gxine < 0.3.3-r1 >= 0.3.3-r1 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== KF of Secure Network Operations has discovered an overflow that occurs during the Content-Type header processing of Kaffeine. The vulnerable code in Kaffeine is reused from gxine, making gxine vulnerable as well. Impact ====== An attacker could create a specially-crafted Content-type header from a malicious HTTP server, and crash a user's instance of Kaffeine or gxine, potentially allowing the execution of arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All Kaffeine users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-video/kaffeine-0.4.3b-r1" All gxine users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-video/gxine-0.3.3-r1" References ========== [ 1 ] SecurityTracker Advisory http://securitytracker.com/alerts/2004/Oct/1011936.html [ 2 ] gxine Bug Report http://sourceforge.net/tracker/index.php?func=detail&aid=1060299&group_id=9655&atid=109655 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200411-14.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.
