SYMPTOMS
You are using a Linux-based client computer in an Active Directory directory service domain where the domain controller is running Microsoft Windows Server 2003 or Microsoft Windows 2000. When the client computer tries to access the domain controller, heap corruption may occur on the domain controller. The heap corruption deletes data from valid memory addresses and generates an access violation in the LSASS service.

Note This access violation causes the domain controller to crash.



CAUSE
This behavior occurs when the following conditions are true:
 * A Linux client computer tries to query the domain controller by using a signed and sealed Lightweight Directory Access Protocol (LDAP) request.
 * The LDAP bind calls use encryption buffers that are smaller than the encryption block size.
