ID: 200704-09

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"
