Microsoft: Windows DNS Denial of Service Vulnerability

An attacker who successfully exploited this vulnerability could cause the DNS service to become nonresponsive. To exploit the vulnerability, an authenticated attacker could send malicious DNS queries to a target, resulting in a denial of service. The update addresses the vulnerability by correcting how Windows DNS processes queries.
