A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
Summary
OpenStack Keystone would allow unintended access over the network.

Details
Boris Bobrov discovered that OpenStack Keystone incorrectly handled
federation mapping when there are rules in which group-based assignments
are not used. A remote authenticated user may receive all the roles
assigned to a project regardless of the federation mapping, contrary to
expectations.

- Ubuntu 16.04 LTS:
- keystone 2:9.3.0-0ubuntu3.1
- python-keystone 2:9.3.0-0ubuntu3.1
