DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Windows, which
can be exploited by malicious people to cause a DoS (Denial of
Service).

1) An error in the TCP/IP stack (Tcpip.sys) when parsing received
ICMP messages can be exploited to cause a system to stop responding
or restart via a sequence of specially crafted ICMP messages.

2) An error in the TCP/IP stack (Tcpip.sys) when parsing URLs can be
exploited to cause a system to stop responding or restart via a
specially crafted URL request to a system serving web content with
URL-based QoS (Quality of Service) enabled (disabled by default).

SOLUTION:
Apply patches.
