Synopsis
========

abcm2ps is vulnerable to a buffer overflow that could lead to remote
execution of arbitrary code.

Background
==========

abcm2ps is a utility used to convert ABC music sheet files into
PostScript format.

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

    -------------------------------------------------------------------
     Package              /  Vulnerable  /                  Unaffected
    -------------------------------------------------------------------
  1  media-sound/abcm2ps      < 3.7.21                       >= 3.7.21

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

Limin Wang has located a buffer overflow inside the put_words()
function in the abcm2ps code.

Impact
======

A remote attacker could convince the victim to download a
specially-crafted ABC file. Upon execution, this file would trigger the
buffer overflow and lead to the execution of arbitrary code with the
permissions of the user running abcm2ps.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All abcm2ps users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-sound/abcm2ps-3.7.21"
