Synopsis

The remote Red Hat host is missing one or more security updates for Red Hat Single Sign-On 7.3.5.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:4042 advisory.

Red Hat Single Sign-On 7.3 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 7.3.5 on RHEL 8 serves as a replacement for Red Hat Single Sign-On 7.3.4, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References.

Security Fix(es):
