Synopsis
========
xine-lib contains a buffer overflow vulnerability which may lead to the
execution of arbitrary code.
Background
==========
xine-lib is the xine core engine. xine is a free multimedia player. It
plays CDs, DVDs, and VCDs, and can also decode other common multimedia
formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 xine-lib < 1.1.2_pre20060328-r1 >= 1.1.2_pre20060328-r1
Description
===========
Federico L. Bossi Bonin discovered that when handling MPEG streams
xine-lib fails to make a proper boundary check of the input data
supplied by the user before copying it to an insufficiently sized
memory buffer.
Impact
======
A remote attacker could entice a user to play a specially-crafted MPEG
file, resulting in the execution of arbitrary code with the permissions
of the user running the application.
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-1.1.2_pre20060328-r1"
