Issue:
======
A flaw in the NTLM Security Support Provider (NTLMSSP) service could
potentially allow a non-administrative user to gain administrative
control over the system. In order to perform this attack the user
would need a valid login account and the ability to execute arbitrary
code on the system.

Mitigating Controls:
====================
 - This vulnerability could only be exploited by an attacker
   who could log onto the affected machine interactively.

 - Servers could only be affected if the attacker were given the
   ability to load a program of her choice onto the machine and
   execute it locally.  Best practices recommend against this.

Patch Availability:
===================
 - A patch is available to fix this vulnerability. Please read the
   Security Bulletin
   http://www.microsoft.com/technet/security/bulletin/ms01-008.asp
   for information on obtaining this patch.
