Date:	11/20/2011
Bugs:	#322859
ID:	201111-12

Synopsis

Multiple vulnerabilities, including buffer overflows, have been found in abcm2ps.

Background

abcm2ps is a program to convert abc files to Postscript files.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-sound/abcm2ps	< 5.9.13	>= 5.9.13	All supported architectures

Description

Multiple vulnerabilities have been discovered in abcm2ps:

Boundary errors in the PUT0 and PUT1 macros, the trim_title() function, or a long "-O" command line option can lead to a buffer overflow (CVE-2010-3441).
A vulnerability in the getarena() function in abc2ps.c can cause a heap-based buffer overflow in abcm2ps (CVE-2010-4743).
Multiple unspecified vulnerabilities (CVE-2010-4744).

Impact

A remote attacker could entice a user to load a specially crafted ABC file or use a long -O option on the command line, resulting in the execution of arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All abcm2ps users should upgrade to the latest stable version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-sound/abcm2ps-5.9.13"

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since August 27, 2010. It is likely that your system is already no longer affected by this issue.
