Synopsis

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

2.  Impact Information

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.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

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-1.1.9.1"
