Arun Babu Neelicattu of Red Hat spotted this commit which introduces a
temporary file creation vulnerability. This issue has been assigned
CVE-2014-0012. For information on how to safely create temporary files
please see
http://kurt.seifried.org/2012/03/14/creating-temporary-files-securely/

For Python simply use ?mkstemp? for files and ?mkdtemp? for
directories from the ?tempfile? module.

MITRE assigned CVE-2014-1402 to this yesterday:

http://seclists.org/oss-sec/2014/q1/71 (the report, the followup has the CVE assignment).

That means you'll need to reject this assignment; the commit that Arun spotted was due to the Debian bug report 
(which the git commit notes, and Ratul linked to in his initial CVE request to the list).


Sorry, I thought the same thing as what Ratul requested for (CVE-2014-1402) was being reported again.  This is indeed 
something different as the git commit to fix CVE-2014-1402 introduced this new temporary file issue.

Sorry for the noise/confusion.
