Synopsis
========
MPlayer contains a remotely exploitable buffer overflow in the HTTP
parser that may allow attackers to run arbitrary code on a user's
computer.
Background
==========
Quote from http://mplayerhq.hu
"MPlayer is a movie player for LINUX (runs on many other Unices, and
non-x86 CPUs, see the documentation). It plays most MPEG, VOB, AVI,
OGG/OGM, VIVO, ASF/WMA/WMV, QT/MOV/MP4, FLI, RM, NuppelVideo, YUV4MPEG,
FILM, RoQ, PVA files, supported by many native, XAnim, and Win32 DLL
codecs. You can watch VideoCD, SVCD, DVD, 3ivx, DivX 3/4/5 and even WMV
movies, too."
Affected packages
=================
-------------------------------------------------------------------
Package/ Vulnerable / Unaffected
-------------------------------------------------------------------
mplayer <= 0.92 >= 0.92-r1
mplayer <= mplayer-1.0_pre2 >= mplayer-1.0_pre2-r1
mplayer <= mplayer-1.0_pre3 >= mplayer-1.0_pre3-r3
Description
===========
A vulnerability exists in the MPlayer HTTP parser which may allow an
attacker to craft a special HTTP header ("Location:") which will trick
MPlayer into executing arbitrary code on the user's computer.
Impact
======
An attacker without privileges may exploit this vulnerability remotely,
allowing arbitrary code to be executed in order to gain unauthorized
access.
Workaround
==========
A workaround is not currently known for this issue. All users are
advised to upgrade to the latest version of the affected package.
Resolution
==========
MPlayer may be upgraded as follows:
x86 and sparc:
# emerge sync
# emerge -pv ">=media-video/mplayer-0.92-r1"
# emerge ">=media-video/mplayer-0.92-r1"
amd64:
# emerge sync
# emerge -pv ">=media-video/mplayer-1.0_pre2-r1"
# emerge ">=media-video/mplayer-1.0_pre2-r1"
ppc:
# emerge sync
# emerge -pv ">=media-video/mplayer-1.0_pre3-r2"
# emerge ">=media-video/mplayer-1.0_pre3-r2"
