Two vulnerabilities have been found in MPlayer which could lead to the remote execution of arbitrary code.

2.  Impact Information


MPlayer is a media player capable of handling multiple multimedia file formats.


Heap overflows have been found in the code handling RealMedia RTSP and Microsoft Media Services streams over TCP (MMST).


By setting up a malicious server and enticing a user to use its streaming data, a remote attacker could possibly execute arbitrary code on the client computer with the permissions of the user running MPlayer.

3.  Resolution Information


There is no known workaround at this time.


All MPlayer users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_pre6-r4"
