Synopsis
========

An attacker may be able to execute arbitrary code by way of specially
crafted MP2 or MP3 files.

Background
==========

mpg123 is a real-time MPEG audio player.

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

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected
    -------------------------------------------------------------------
  1  media-sound/mpg123     < 0.59s-r9                     >= 0.59s-r9

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

mpg123 improperly parses frame headers in input streams.

Impact
======

By inducing a user to play a malicious file, an attacker may be able to
exploit a buffer overflow to execute arbitrary code with the
permissions of the user running mpg123.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All mpg123 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-sound/mpg123-0.59s-r9"
