Vulnerability Name:

CCN-530

Published:1997-06-01
Updated:1997-06-01
Summary:Windows NT Routing and RAS Service does not support the concept of established connections, whereby one rule can be used to permit or deny two way communication over any protocol to any host. This allows an attacker to bypass filtering rules and possibly force processes to terminate, or to flood the affected ports.
