xine-lib: Heap-based buffer overflow — GLSA 200704-09

xine-lib is vulnerable to a heap-based buffer overflow.

Affected Packages

media-libs/xine-lib on the x86 architecture
Affected versions < 1.1.4-r2
Unaffected versions >= 1.1.4-r2

Background

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

Description

xine-lib does not check boundaries on data being read into buffers from DMO video files in code that is shared with MPlayer (DMO_VideoDecoder.c).

Impact

An attacker could entice a user to play a specially crafted DMO video file 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 on the x86 platform should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.4-r2"
