Thank you for requesting a CVE Cedric.  I have additional information
about this bug, including an additional exploitation path, which I
shared with Python security on January 14, 2016.  Unfortunately, they
have apparently failed to act to notify the public or acquire a CVE.
(They stopped responding to me months ago.)  I'll post the additional
information soon, once I am back at my desk.

In the mean time, do you happen to have specific information on which
versions of the 2.x and 3.x upstream branches were affected/fixed?
