keystone vulnerability

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.

Software Description

  • keystone - OpenStack identity service

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

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

In general, a standard system update will make all the necessary changes.
