Problem Description:

 An exploitable buffer overflow was discovered in the Samba server that
 can lead to an anonymous remote root compromise.  The Samba Team also
 discovered some potential overflows during an internal code audit which
 was done in response to the previously noted buffer overflow problem.
 
 All versions of Samba prior to 2.2.8a are vulnerable.  The provided
 updates contain a patch from the Samba Team to correct the issue.
 
 An exploit is known to exist and all Mandrake Linux users are 
 encouraged to upgrade immediately.
