Description

The remote host is affected by a denial of service vulnerability in Active Directory Services and Active Directory Lightweight Directory Services (AD LDS).

By sending a specially crafted query to the Lightweight Directory Access Protocol (LDAP) service, an attacker can cause the directory service to stop responding until an administrator restarts the service.
