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"
