Severity: High Title: MPlayer, xine-lib: vulnerabilities in RTSP stream handling 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"
