<p>
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.
</p>

<description>
<p>
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.
</p>
</description>
<impact type="high">
<p>
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.
</p>
</impact>
<workaround>
<p>
For MPlayer, there is no known workaround at this time. For xine-lib, you
can delete the xineplug_inp_rtsp.so file.
</p>
</workaround>
<resolution>
<p>
All users should upgrade to non-vulnerable versions of MPlayer and
xine-lib:
</p>
<code>
# 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"</code>
</resolution>
