Synopsis
========

mpg123 is vulnerable to a buffer overflow that allows an attacker to
execute arbitrary code through the use of a malicious playlist.

Background
==========

mpg123 is a MPEG Audio Player.

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

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected
    -------------------------------------------------------------------
  1  media-sound/mpg123     < 0.59s-r8                     >= 0.59s-r8

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

Bartlomiej Sieka discovered that mpg123 contains an unsafe strcat() to
an array in playlist.c. This code vulnerability may lead to a buffer
overflow.

Impact
======

A remote attacker could craft a malicious playlist which, when used,
would result in the execution of arbitrary code with the rights 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-r8"
