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

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

Affected packages
================
    -------------------------------------------------------------------
     Package              /    Vulnerable    /              Unaffected
    -------------------------------------------------------------------
  1  media-video/mplayer      < 1.0_pre6-r4             >= 1.0_pre6-r4

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"
