Gentoo Linux Security Advisory

Title: MPlayer: Heap overflow in ad_pcm.c (GLSA 200509-01)
Severity: normal
Exploitable: remote
Date: September 01, 2005
Bug(s): #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: media-video/mplayer
Vulnerable: < 1.0_pre7-r1
Unaffected: >= 1.0_pre7-r1
Architectures: All supported architectures


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_pre7-r1"
