MPlayer: Two heap overflow vulnerabilities

Background

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

Description

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

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All MPlayer users should upgrade to the latest version:

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