Software: Windows NT 4.0
Impact: Privilege Elevation
Bulletin: MS01-008

Microsoft encourages customers to review the Security Bulletin at:
http://www.microsoft.com/technet/security/bulletin/ms01-008.asp

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.
