DESCRIPTION:
ISS X-Force has discovered a vulnerability in Microsoft Windows,
which can be exploited by malicious people to cause a DoS (Denial of
Service).

The vulnerability is caused due to a NULL pointer dereference error
in the Server driver (srv.sys) when processing certain SMB (Server
Message Block) data and can be exploited by sending a specially
crafted network packet to a vulnerable system.

Successful exploitation crashes the system.

The vulnerability has been confirmed on Windows XP SP2 (fully
patched). Other versions are reportedly also affected.

SOLUTION:
Restrict traffic to ports 135-139 and 445.

PROVIDED AND/OR DISCOVERED BY:
Tom Cross, David Means, and Scott Warfield of ISS X-Force.
