Red Hat Security Advisory: Red Hat Single Sign-On 7.2 security update

Notes

Topic
A security update is now available for Red Hat Single Sign-On 7.2 from the Customer Portal. 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.
Details
Red Hat Single Sign-On 7.2 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 asynchronous patch is a security update for wildfly-core and apache-cxf packages in Red Hat Single Sign-On 7.2. Security Fix(es): * apache-cxf: TLS hostname verification does not work correctly with com.sun.net.ssl.* (CVE-2018-8039) * wildfly-core: Path traversal can allow the extraction of .war archives to write arbitrary files. (CVE-2018-10862)
