Using a specially malformed share enumeration request, an attacker can cause the Service Control Manager (Server service) to misbehave and access illegal memory areas. As a result, the server service will be terminated, resulting in the loss of remote services to the affect machine. These include all services that use named pipes. This results in a seriously degraded system that will likely be unusable for any normal purpose. This attack is known to affect unpatched Windows NT 4 (and its flavors) systems through Microsoft Service pack 6.Note: This signature is only available in Cisco IDS versions 4.0 and greater.
