Description Kurt Seifried 2013-12-06 19:44:10 UTC 
Jeremy Stanley of the OpenStack	Project	reports:

Steven Hardy from Red Hat reported a vulnerability in Keystone
trusts when used in conjunction with the ec2tokens API. By
generating EC2 credentials using a trust-scoped token, a trustee may
retrieve a token not scoped to the trust, therefore elevating
privileges to all of the trustor's roles. Only Keystone setups
enabling EC2-style authentication are affected.
