Summary
Red Hat Security Advisory: openstack-keystone security update

Notes

Topic
An update for openstack-keystone is now available for Red Hat OpenStack Platform 16 (Train). Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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) * OAuth1 request token authorize silently ignores roles parameter (CVE-2020-12690) * Credentials endpoint policy logic allows changing credential owner and target project ID (CVE-2020-12691) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.
