The remote host is affected by a denial of service vulnerability.


The remote Windows host is affected by a denial of service vulnerability in the Internet Protocol Security (IPSec) service due to improper handling of encryption negotiation. An authenticated, remote attacker can exploit this, via a malicious application, to cause the host to become unresponsive.
