File :
/usr/lib/python2.7/distutils/command/bdist_rpm.py

Line 358 :
This line in the code uses the depreached os.popen command, should be replaced with supbprocess.Popen() :

out = os.popen(q_cmd)

Exploit demo :
============
1) Download the setup.py script wich i attached
2) Create a test folder an put the setup.py script in this folder
3) cd to the test folder
4) python setup.py bdist_rpm
5) A xmessage window pops up as a proof of concept
