Description

The remote version of Active Directory contains a flaw in the LDAP request handler code that allows an attacker to execute code on the remote host.

On Windows 2000 an anonymous attacker can exploit this flaw by sending a specially crafted LDAP packet. On Windows 2003 valid credentials are needed to exploit it.

Additionally, the Active Directory is affected by a remote denial of service vulnerability.
