Bug description:
  
  The suds project appears to be largely unmaintained upstream. The default cache implementation stores pickled objects to a predictable path in /tmp. This can be used by a local attacker to redirect SOAP requests via symlinks or run a privilege escalation / code execution attack via a pickle exploit.

  The details are available here -

  (CVE-2013-2217)

  Although this is an unlikely attack vector steps should be taken to
  prevent this behaviour. Potential ways to fix this are by explicitly
  setting the cache location to a directory created via
  tempfile.mkdtemp(), disabling cache client.set_options(cache=None), or
  using a custom cache implementation that doesn't load / store pickled
  objects from an insecure location.
