===========================================================
Ubuntu Security Notice USN-128-1	       May 17, 2005
nasm vulnerability
CAN-2005-1194
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)

The following packages are affected:

nasm

The problem can be corrected by upgrading the affected package to
version 0.98.38-1ubuntu0.2 (for Ubuntu 4.10), or 0.98.38-1.1ubuntu0.1
(for Ubuntu 5.04).  In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Josh Bressers discovered a buffer overflow in the ieee_putascii()
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.

Updated packages for Ubuntu 4.10 (Warty Warthog):
