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

The vulnerability is caused due to the Secure Channel (SChannel)
security package failing to check a logical condition when parsing
client certificates. This can be exploited to cause the LSASS service
to stop responding and restart the system via a specially crafted
client certificate request to an affected IIS server hosting a
SSL-enabled web site.

SOLUTION:
Apply patches.
