Comment 2 Ralph Bean 2013-05-24 00:41:38 UTC

Vincent, python-requests no longer bundles the match_hostname code as of python-requests-1.1.0-3.

See:

* http://pkgs.fedoraproject.org/cgit/python-requests.git/log/h
* https://admin.fedoraproject.org/updates/python-requests
* https://bugzilla.redhat.com/show_bug.cgi?id=904623

The bug should be filed against python-backports-ssl_match_hostname.  There is no new update to be pushed for this package.  How should we proceed?  Close this ticket by hand?  Please advise.

Comment 3 Toshio Ernie Kuratomi 2013-05-24 15:28:03 UTC

The bundled version of the code was removed in February 2013.

python-backports-ssl_match_hostname update patched for this bug  is currently in the testing repository: https://admin.fedoraproject.org/updates/python-backports-ssl_match_hostname

Comment 4 Vincent Danen 2013-05-27 18:37:39 UTC

Toshio did the right thing; this should be closed and the fix should be in the python-backports-ssl_match_hostname package, so while this is vulnerable now, it won't be once the other package is updated.
