xine-lib: User-assisted execution of arbitrary code


1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 200801-12 / xine-lib
Release Date January 27, 2008
Latest Revision January 27, 2008: 01
Impact normal
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
media-libs/xine-lib < >= All supported architectures

Related bugreports: #205197


xine-lib is vulnerable to multiple heap-based buffer overflows when processing RTSP streams.

2.  Impact Information


xine-lib is the core library package for the xine media player.


Luigi Auriemma reported that xine-lib does not properly check boundaries when processing SDP attributes of RTSP streams, leading to heap-based buffer overflows.


An attacker could entice a user to play specially crafted RTSP 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.

3.  Resolution Information


There is no known workaround at this time.


All xine-lib users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/xine-lib-"
