A vulnerability in the Active Directory could be exploited into causing the service to become non-responsive.
Microsoft has released a security update to address a denial of service vulnerability in the Active Directory. The vulnerability was caused by a failure to handle a specially crafted Lightweight Directory Access Protocol (LDAP) query, and it can be exploited into causing the service to stop responding.
This issue has been resolved through the latest update which introduces a correction in the way that LDAP queries are handled. Users are recommended to install the update as a protection measure against possible exploit attempts.
