Date: April 7th, 2003

Affected versions: 8.2, 9.0, 9.1, Corporate Server 2.1,
Multi Network Firewall 8.2
________________________________________________________________________

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.
