All supported architectures
Multiple vulnerabilities, including buffer overflows, have been
found in abcm2ps.
abcm2ps is a program to convert abc files to Postscript files.
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
- 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).
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.
There is no known workaround at this time.
All abcm2ps users should upgrade to the latest stable version:
Code Listing 3.1: Resolution
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/abcm2ps-5.9.13"
NOTE: This is a legacy GLSA. Updates for all affected architectures are

no longer affected by this issue.
