Description

The installed version of Microsoft Active Directory / Active Directory Application Mode / Active Directory Lightweight Directory Service has a buffer overflow vulnerability. By sending specially crafted LDAP or LDAPS requests, a remote attacker can exhaust stack space and cause the affected host to stop responding until it is restarted.
