Microsoft Windows DNS Server is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause the DNS server service to stop responding, denying service to legitimate users.
Block external access at the network boundary, unless external parties require service.
Filter access to the affected computer at the network boundary if global access isnât needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
Disallow anonymous access to services. Permit access for trusted individuals only.
Restrict access to trusted and accountable users only.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Use NIDS to detect suspicious or anomalous network traffic. Monitor logs for signs of malicious activity.
Updates are available. Please see the references or vendor advisory for more information.
