nasm security update

CentOS Errata and Security Advisory CESA-2005:381-01

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 CAN-2004-1287
and CAN-2005-1194 to these issues.

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