Synopsis
========

When compiled with GUI support MPlayer is vulnerable to a remotely
exploitable buffer overflow attack.

Background
==========

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

Affected packages
=================

    -------------------------------------------------------------------
     Package              /    Vulnerable    /             Unaffected
    -------------------------------------------------------------------
  1  media-video/mplayer      < 1.0_pre4-r7            >= 1.0_pre4-r7

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

The MPlayer GUI code contains several buffer overflow vulnerabilities,
and at least one in the TranslateFilename() function is exploitable.

Impact
======

By enticing a user to play a file with a carefully crafted filename an
attacker could execute arbitrary code with the permissions of the user
running MPlayer.

Workaround
==========

To work around this issue, users can compile MPlayer without GUI
support by disabling the gtk USE flag. All users are encouraged to
upgrade to the latest available version of MPlayer.

Resolution
==========

All MPlayer users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=media-video/mplayer-1.0_pre4-r7"
    # emerge ">=media-video/mplayer-1.0_pre4-r7"
