"An updated nasm package that fixes multiple security issues is now
available.

This update has been rated as having low security impact by the Red
Hat Security Response Team.

NASM is an 80x86 assembler.

Two stack based buffer overflow bugs have been found in nasm. An
attacker could create an ASM file in such a way that when compiled by
a victim, could execute arbitrary code on their machine. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
names CVE-2004-1287 and CVE-2005-1194 to these issues.

All users of nasm are advised to upgrade to this updated package,
which contains backported fixes for these issues."
