Upgrade keystone to version 17.0.0 or higher.

Overview

keystone is a package that provides authentication, authorization and service discovery mechanisms via HTTP primarily for use by projects in the OpenStack family.

Affected versions of this package are vulnerable to Improper Access Control. The list of roles provided for an OAuth1 access token is silently ignored. Thus, when an access token is used to request a keystone token, the keystone token contains every role assignment the creator had for the project. This results in the provided keystone token having more role assignments than the creator intended, possibly giving unintended escalated access.
