Synopsis
========

mpg123 decoding routines contain a buffer overflow bug that might lead
to arbitrary code execution.

Background
==========

mpg123 is a MPEG Audio Player.

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

    -------------------------------------------------------------------
     Package             /   Vulnerable   /                 Unaffected
    -------------------------------------------------------------------
  1  media-sound/mpg123      <= 0.59s-r3                   >= 0.59s-r4

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

mpg123 contains a buffer overflow in the code that handles layer2
decoding of media files.

Impact
======

An attacker can possibly exploit this bug with a specially-crafted mp3
or mp2 file 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 -pv ">=media-sound/mpg123-0.59s-r4"
    # emerge ">=media-sound/mpg123-0.59s-r4"
