Description

A denial of service vulnerability exists in Windows DNS Server when it fails to properly handle DNS queries. An attacker who successfully exploited this vulnerability could cause the DNS Server service to become nonresponsive. To exploit the vulnerability, an unauthenticated attacker could send malicious DNS queries to an affected server, resulting in a denial of service. However, the DNS server must be configured to use DNS Analytical Logging for the attack to succeed. The update addresses the vulnerability by correcting how Windows DNS Server processes DNS queries.
