Severity: Normal Title: MPlayer: Heap overflow in ad_pcm.c Date: September 01, 2005 Bugs: #103555 ID: 200509-01

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"
