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 an error within the TCP/IP stack, which remains in TCP FIN_WAIT_2 state after receiving an ACK to the FIN packet when handling a teardown sequence. This can be exploited to exhaust the non-paged pool and render the system unusable or trigger a restart.

Successful exploitation requires having the victim machine initiate the teardown sequence.


Solution:
Apply updates.
