Vulnerability Assessment Details
MPlayer, xine-lib: vulnerabilities in RTSP stream handling
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200405-24
(MPlayer, xine-lib: vulnerabilities in RTSP stream handling)
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.
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 xineplug_inp_rtsp.so 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"
