Title:
  Remote code execution

Status in OpenObject GTK Client:
  New

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
