Samba < 3.0.28 send_mailslot Function Remote Buffer Overflow

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.

Synopsis :

The remote Samba server may be affected by a buffer overflow

Description :

According to its banner, the version of the Samba server on the remote
host is reportedly affected by a boundary error in 'nmbd' within the
'send_mailslot' function. Provided the 'domain logons' option is
enabled in 'smb.conf', an attacker can leverage this issue to produce
a stack-based buffer overflow using a 'SAMLOGON' domain logon packet
in which the username string is placed at an odd offset and is
followed by a long 'GETDC' string.

Note that Nessus has not actually tried to exploit this issue nor
verify whether the 'domain logons' option has been enabled on the
remote host.

Solution :
