DESCRIPTION:
Dmitry Oleksiuk has discovered a vulnerability in Microsoft Windows,
which can be exploited by malicious, local users to cause a DoS
(Denial of Service).

The vulnerability is caused due to an error in atmfd.dll when
processing Adobe OpenType font files and can be exploited to cause a
excessive CPU consumption and potentially crash the system.

The vulnerability is confirmed on a fully patched Windows XP SP3
(atmfd.dll version 5.1.2.232). Other versions may also be affected.

SOLUTION:
Restrict access to trusted users only.
