xine-lib: User-assisted execution of arbitrary code

Background

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

Description

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

Impact

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.

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-1.1.9.1"
