   Update samba package to 3.6.25.

                      ==============================
                      Release Notes for Samba 3.6.25
                             February 23, 2015
                      ==============================

   This is a security release in order to address CVE-2015-0240 (Unexpected
   code execution in smbd).

   o  CVE-2015-0240:
      All versions of Samba from 3.5.0 to 4.2.0rc4 are vulnerable to an
      unexpected code execution vulnerability in the smbd file server
      daemon.

      A malicious client could send packets that may set up the stack in
      such a way that the freeing of memory in a subsequent anonymous
      netlogon packet could allow execution of arbitrary code. This code
      would execute with root privileges.

   o  CVE-2014-0178:
      In preparing a response to an authenticated FSCTL_GET_SHADOW_COPY_DATA
      or FSCTL_SRV_ENUMERATE_SNAPSHOTS client request, affected versions of
      Samba do not initialize 8 bytes of the 16 byte SRV_SNAPSHOT_ARRAY
      response field. The uninitialized buffer is sent back to the client.

      A non-default VFS module providing the get_shadow_copy_data_fn() hook
      must be explicitly enabled for Samba to process the aforementioned
      client requests. Therefore, only configurations with "shadow_copy" or
      "shadow_copy2" specified for the "vfs objects" parameter are vulnerable.
