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

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

mpg123 improperly parses frame headers in input streams.

Impact

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
