Synopsis :

The remote Windows host is susceptible to denial of service attacks.

Description :

The TCP/IP stack in use on the remote Windows host is potentially
affected by the following denial of service vulnerabilities :

- By sending a sequence of specially crafted ICMP

automatically reboot. (CVE-2011-1871)

- By sending a request with a specially crafted URL, an
unauthenticated, remote attacker may be able to cause
the affected host to stop responding and automatically
reboot if it is serving web content and has URL-based
QoS (Quality of Service) enabled. (CVE-2011-1965)
