Synopsis
========
A heap overflow in MPlayer might lead to the execution of arbitrary
code.
Background
==========
MPlayer is a media player capable of handling multiple multimedia file
formats.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-video/mplayer < 1.0_pre7-r1 >= 1.0_pre7-r1
Description
===========
Sven Tantau discovered a heap overflow in the code handling the strf
chunk of PCM audio streams.
Impact
======
An attacker could craft a malicious video or audio file which, when
opened using MPlayer, would end up executing arbitrary code on the
victim's computer with the permissions of the user running MPlayer.
Workaround
==========
You can mitigate the issue by adding "ac=-pcm," to your MPlayer
configuration file (note that this will prevent you from playing
uncompressed audio).
Resolution
==========
All MPlayer users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_pre7-r1"
