Comment 1 Paul Howarth 2017-01-19 10:20:59 UTC 
Is EL-6's python-cryoto package not affected by this?
Comment 2 Paul Howarth 2017-01-19 10:21:41 UTC 
Whoops, typo there, I meant python-crypto.
Comment 3 Chandrani 2017-08-07 10:38:23 UTC 
Hi,
   Is this fix available as a part of pycrypto-2.6.1-py2.py3-none-any.whl. If not then in which release it will be bundled??

Thanks in advance.
Comment 4 Paul Howarth 2017-08-07 10:48:51 UTC 
There is no upstream release containing a fix for this issue, and there's no real prospect of there being one any time soon.

The lack of a fix for this is leading many other projects to move away from python-crypto (pycrypto) to other libraries such as python-cryptography instead.

RHUI 3 doesn't appear to use the affected code, emailed them to confirm, no reply yet.
Comment 7 Mark Knowles 2017-12-15 21:11:45 UTC 
kseifried advised that RHUI is unaffected.
