DESCRIPTION:
Dejan Levaja has reported a vulnerability in Microsoft Windows,
allowing malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to improper handling of IP packets
with the same destination and source IP and the SYN flag set. This
causes a system to consume all available CPU resources for a certain
period of time.

This kind of attack was first reported in 1997 and became known as
LAND attacks.

Microsoft Windows XP with SP2 and Microsoft Windows 2003 have been
reported vulnerable.


SOLUTION:
Filter traffic with the same IP address as source and destination
address at the perimeter.

PROVIDED AND/OR DISCOVERED BY:
Dejan Levaja
