Notes

Topic
A new image is available for Red Hat Single Sign-On 7.6.6, running on OpenShift Container Platform 3.10 and 3.11, and 4.3. Red Hat Product Security has rated this update as having a security impact of Moderate. 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
Red Hat Single Sign-On is an integrated sign-on solution, available as a Red Hat JBoss Middleware for OpenShift containerized image. The Red Hat Single Sign-On for OpenShift image provides an authentication server that you can use to log in centrally, log out, and register. You can also manage user accounts for web applications, mobile applications, and RESTful web services. This erratum releases a new image for Red Hat Single Sign-On 7.6.6 for use within the OpenShift Container Platform 3.10, OpenShift Container Platform 3.11, and OpenShift Container Platform 4.3 cloud computing Platform-as-a-Service (PaaS) for on-premise or private cloud deployments, aligning with the standalone product release. Security Fix(es): * open redirect via "form_post.jwt" JARM response mode (CVE-2023-6927) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
