The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:3045 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 7.3.4 on RHEL 7 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)
