    descriptionNew Red Hat Single Sign-On 7.3.4 packages are now available for Red Hat Enterprise Linux 8. 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. 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 7.3.4 on RHEL 8 serves as a replacement for Red Hat Single Sign-On 7.3.3, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Security Fix(es) : * keycloak: cross-realm user access auth bypass (CVE-2019-14832) * keycloak: adapter endpoints are exposed via arbitrary URLs (CVE-2019-14820) * jackson-databind: polymorphic typing issue allows attacker to read arbitrary local files on the server via crafted JSON message (CVE-2019-12814) * jackson-databind: default typing mishandling leading to remote code execution (CVE-2019-14379) * jackson-databind: polymorphic typing issue allows attacker to read arbitrary local files on the server (CVE-2019-12086) * undertow: Information leak in requests for directories without trailing slashes (CVE-2019-10184) 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.

    descriptionNew Red Hat Single Sign-On 7.3.4 packages are now available for Red Hat Enterprise Linux 6. 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. 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 7.3.4 on RHEL 6 serves as a replacement for Red Hat Single Sign-On 7.3.3, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Security Fix(es) : * keycloak: cross-realm user access auth bypass (CVE-2019-14832) * keycloak: adapter endpoints are exposed via arbitrary URLs (CVE-2019-14820) * jackson-databind: polymorphic typing issue allows attacker to read arbitrary local files on the server via crafted JSON message (CVE-2019-12814) * jackson-databind: default typing mishandling leading to remote code execution (CVE-2019-14379) * jackson-databind: polymorphic typing issue allows attacker to read arbitrary local files on the server (CVE-2019-12086) * undertow: Information leak in requests for directories without trailing slashes (CVE-2019-10184) 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.
