Synopsis
========
xine-lib is vulnerable to a heap-based buffer overflow.
Background
==========
xine-lib is the core library package for the xine media player.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/xine-lib < 1.1.4-r2 >= 1.1.4-r2
-------------------------------------------------------------------
# Package 1 only applies to x86 users.
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"
