Synopsis
========

Buffer overflow vulnerabilities have been found in mpg123 which could
lead to execution of arbitrary code.

Background
==========

mpg123 is a MPEG Audio Player.

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

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected
    -------------------------------------------------------------------
  1  media-sound/mpg123     < 0.59s-r5                     >= 0.59s-r5

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

Buffer overflow vulnerabilities in the getauthfromURL() and http_open()
functions have been reported by Carlos Barros. Additionally, the Gentoo
Linux Sound Team fixed additional boundary checks which were found to
be lacking.

Impact
======

By enticing a user to open a malicious playlist or URL or making use of
a specially-crafted symlink, an attacker could possibly execute
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-r5"
