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.
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 type="high">
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.
For MPlayer, there is no known workaround at this time. For xine-lib, you
can delete the file.
All users should upgrade to non-vulnerable versions of MPlayer and
# 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>
