DESCRIPTION:
A vulnerability has been reported in Microsoft Windows, which can be
exploited by malicious people to cause a DoS (Denial of Service) or
potentially compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the TCP/IP
protocol driver within the IP source routing mechanism and can be
exploited via a specially crafted IP packet.

According to the vendor, successful exploitation most likely causes a
crash, but may potentially allow execution of arbitrary code. However,
exploitation requires that "IP Source Routing" is enabled (disabled by
default on Windows XP SP2 and Windows Server 2003 SP1) or the "Routing
and Remote Access Service" is enabled (disabled by default).

SOLUTION:
Apply patches.
