Public bug reported:

The smbd daemon maintains internal data structures used track
active connections to file and printer shares.  In certain
circumstances an attacker may be able to continually increase
the memory usage of an smbd process by issuing a large number
of share connection requests.  This defect affects all Samba 
configurations.
