Synopsis
nasm security update
Type/Severity
Security Advisory: Low
Topic
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.
Description
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.
