DESCRIPTION:
A vulnerability has been reported in Microsoft Windows, which can be
exploited by malicious users to cause a DoS (Denial of Service).

The vulnerability is cause due to a NULL-pointer dereference error in
the Netlogon RPC Service of a domain controller and can be exploited
to cause a server to restart via a specially crafted RPC packet.

Successful exploitation requires an attacker to have administrator
privileges on a machine that is joined to the affected domain.

SOLUTION:
Apply patches.
