Background ========= xine-lib is the core library package for the xine media player. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/xine-lib < 1.1.10.1 > = 1.1.10.1 Description ========== Damian Frizza and Alfredo Ortega (Core Security Technologies) discovered a stack-based buffer overflow within the open_flac_file() function in the file demux_flac.c when parsing tags within a FLAC file (CVE-2008-0486). A buffer overflow when parsing ASF headers, which is similar to CVE-2006-1664, has also been discovered. Impact ===== A remote attacker could entice a user to play specially crafted FLAC or ASF video streams with a player using xine-lib, potentially resulting in the execution of arbitrary code with the privileges of the user running the player. 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-1.1.10.1" References ========= [ 1 ] CVE-2006-1664 https://www.cve.org/CVERecord?id=CVE-2006-1664 [ 2 ] CVE-2008-0486 https://www.cve.org/CVERecord?id=CVE-2008-0486 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200802-12 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.
