(RHSA-2020:2732) Important: openstack-keystone security update

The OpenStack Identity service (keystone) authenticates and authorizes
OpenStack users by keeping track of users and their permitted activities.
The Identity service supports multiple forms of authentication, including
user name and password credentials, token-based systems, and AWS-style
logins.

Security Fix(es):

• EC2 and credential endpoints are not protected from a scoped context
  (CVE-2020-12689)

• Credentials endpoint policy logic allows changing credential owner and
  target project ID (CVE-2020-12691)

• failure to check signature TTL of the EC2 credential auth method
  (CVE-2020-12692)
