trunk/openobject-server/bin> find . -name "*py" |xargs grep -i pickle
returns some modules where pickle is used instead of cPickle
I assume at least speed improvement could be achieved at no cost.

Bug description:
  It's possible to execute arbritrary code on client using net-rpc
  (pickle protocol) see http://nadiana.com/python-pickle-insecure

  If you use the client to connect to some demo server and this demo
  server is malicious, it can send malicious code which is executed in
  client side.

  I attach a exploit server who sends code to execute to client. Run a
  ls -l and redirect the output to proof_of_exploit.txt file.

  This bug was fixed in the server, but not in the client.
  Affects versions 4.2, 5.X and 6.X
