Red Hat Security Advisory: Red Hat Single Sign-On 7.4.6 security update on RHEL 8

Notes

Topic
New Red Hat Single Sign-On 7.4.6 packages are now available for Red Hat Enterprise Linux 8. Red Hat Product Security has rated this update as having a security impact of Low. 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 a standalone server, based on the Keycloak project, that provides authentication and standards-based single sign-on capabilities for web and mobile applications. This release of Red Hat Single Sign-On 7.4.6 on RHEL 8 serves as a replacement for Red Hat Single Sign-On 7.4.5, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Security Fix(es): * nodejs-angular: XSS due to regex-based HTML replacement (CVE-2020-7676) * keycloak: reusable "state" parameter at redirect_uri endpoint enables possibility of replay attacks (CVE-2020-14302) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
