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

  for information on obtaining this patch.
