http://security.gentoo.org/

Severity:	normal
Title:	abcm2ps: Buffer overflow vulnerability
Date:	12/19/2004
Bugs:	#74702
ID:	200412-18

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	Architecture(s)
media-sound/abcm2ps	< 3.7.21	>= 3.7.21	All supported architectures

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"
