Bug description:
  Since python-crypto 2.6.1-6ubuntu0.16.04.1 landed, it seems python-
  paramiko 1.16.0-1 is not working anymore.

  /usr/lib/python2.7/dist-packages/paramiko/client.pyc in connect(self, hostname, port, username, password, pkey, key_filename, timeout, allow_agent, look_for_keys, compress, sock, gss_auth, gss_kex, gss_deleg_creds, gss_host, banner_timeout)
      323         if banner_timeout is not None:
      324             t.banner_timeout = banner_timeout
  --> 325         t.start_client()
      326         ResourceManager.register(self, t)
      327 

  /usr/lib/python2.7/dist-packages/paramiko/transport.pyc in start_client(self, event)
      490                 e = self.get_exception()
      491                 if e is not None:
  --> 492                     raise e
      493                 raise SSHException('Negotiation failed.')
      494             if event.is_set():

  ValueError: CTR mode needs counter parameter, not IV

  Seems related to the fix for CVE-2013-7459
