Description Agostino Sarubbo gentoo-dev 2016-05-18 10:13:19 UTC
From ${URL} :

A vulnerability was found in the Keystone Fernet Token Provider. By rescoping a token a user will 
receive a new token without correct audit_ids, these incorrect audit_ids will prevent the entire 
chain of tokens from being revoked properly. This vulnerability does not impact revoking a token by 
it's individual audit_id. Only deployments with Keystone configured to use Fernet tokens are 
impacted.

I've confirmed that <keystone-9 is not impacted by this bug.  I've patched and removed the badness, removing myself/project as we are completed here.
