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"
