Security: Patche for CVE-2008-1105.

    -- Summary --
    Specifically crafted SMB responses can result
    in a heap overflow in the Samba client code.
    Because the server process, smbd, can itself
    act as a client during operations such as
    printer notification and domain authentication,
    this issue affects both Samba client and server
    installations.

Ensure that we specify the buffer size used to store incoming SMB
packets.  This bug was originally introduced in Samba 2.2.4.  Patch from
Jeremy Allison.
