Date: May 28, 2004
Bugs: #49387
ID: 200405-24

Synopsis
========
Multiple vulnerabilities, including remotely exploitable buffer
overflows, have been found in code common to MPlayer and the xine
library.
Background
==========
MPlayer is a movie player capable of handling multiple multimedia file
formats. xine-lib is a multimedia player library used by several
graphical user interfaces, including xine-ui. They both use the same
code to handle Real-Time Streaming Protocol (RTSP) streams from
RealNetworks servers.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-video/mplayer < 1.0_pre4 >= 1.0_pre4
<= 0.92-r1
2 media-libs/xine-lib < 1_rc4 >= 1_rc4
<= 0.9.13-r3
Description
===========
Multiple vulnerabilities have been found and fixed in the RTSP handling
code common to recent versions of these two packages. These
vulnerabilities include several remotely exploitable buffer overflows.
Impact
======
A remote attacker, posing as a RTSP stream server, can execute
arbitrary code with the rights of the user of the software playing the
stream (MPlayer or any player using xine-lib). Another attacker may
entice a user to use a maliciously crafted URL or playlist to achieve
the same results.
Workaround
==========
For MPlayer, there is no known workaround at this time. For xine-lib,
you can delete the xineplug_inp_rtsp.so file.
Resolution
==========
All users should upgrade to non-vulnerable versions of MPlayer and
xine-lib:
# emerge sync
# emerge -pv ">=media-video/mplayer-1.0_pre4"
# emerge ">=media-video/mplayer-1.0_pre4"
# emerge -pv ">=media-libs/xine-lib-1_rc4"
# emerge ">=media-libs/xine-lib-1_rc4"
