Synopsis
========

Multiple overflow vulnerabilities have been found in MPlayer,
potentially resulting in remote executing 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_pre5-r4             >= 1.0_pre5-r5

Description
===========

iDEFENSE, Ariel Berkman and the MPlayer development team found multiple
vulnerabilities in MPlayer. These include potential heap overflows in
Real RTSP and pnm streaming code, stack overflows in MMST streaming
code and multiple buffer overflows in BMP demuxer and mp3lib code.

Impact
======

A remote attacker could craft a malicious file or design a malicious
streaming server. Using MPlayer to view this file or connect to this
server could trigger an overflow and execute attacker-controlled code.

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_pre5-r5"
