Subject: [Full-Disclosure] [USN-45-1] nasm vulnerability

===========================================================
Ubuntu Security Notice USN-45-1		  December 22, 2004
nasm vulnerability
CAN-2004-1287
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

nasm

The problem can be corrected by upgrading the affected package to
version 0.98.38-1ubuntu0.1.  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Jonathan Rockway discovered a locally exploitable buffer overflow in
the error() function of nasm. If an attacker tricked a user into
assembling a malicious source file, they could exploit this to execute
arbitrary code with the privileges of the user that runs nasm.
