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 lt; 1.0_pre6-r4 gt;= 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 "gt;=media-video/mplayer-1.0_pre6-r4"
