Red Hat Security Advisory 2014-1084-01 - OpenStack Compute launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances, managing networks, and controlling access through users and projects. It was found that RBAC policies were not enforced in certain methods of the OpenStack Compute EC2 API. A remote attacker could use this flaw to escalate their privileges beyond the user group they were originally restricted to. Note that only certain setups using non-default RBAC rules for OpenStack Compute were affected.
