Samba 3.6.x < 3.6.3 Denial of Service

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.

Synopsis :

The remote Samba server is affected by a denial of service

Description :

According to its banner, the version of Samba 3.6.x running on the
remote host is earlier than 3.6.3. Errors exist in the files
'source3/lib/substitute.c' and 'sources3/smbd/server.c' that leak
small amounts of memory when processing every connection attempt.

An attacker can continually make connections to the server and cause a
denial of service attack against the affected smbd service.

Note that Nessus has not actually tried to exploit this issue or
otherwise determine if the patch has been applied.
