Description Kurt Seifried 2013-08-22 15:56:15 UTC

Vincent Danen (vdanen) reports:

The previous fix was insufficient and did not fully fix the flaw, as noted here:

https://bugs.launchpad.net/ossa/+bug/1212179

The patch to fully correct this flaw is here (I believe it would be in addition to previously-mentioned patches):

https://github.com/openstack/nova/commit/4054cc4a22a1fea997dec76afb5646fd6c6ea6b9
