Windows DNS Denial of Service Vulnerability
A denial of service vulnerability exists in Windows DNS when it fails to properly handle queries. 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.
