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"
