✅ Remediation
Before applying this update, make sure all previously released errata relevant to your system have been applied. Also, make sure to back up any modified configuration files, deployments, and all user data. After applying the update, restart the instance of Red Hat JBoss Enterprise Application Platform for the changes to take effect. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258 Workaround: Users should upgrade to Apache Standard Taglibs 1.2.3 or later. This version uses JAXP’s FEATURE_SECURE_PROCESSING to restrict XML processing. Depending on the Java runtime version in use, additional configuration may be required: Java8: External entity access is automatically disabled if a SecurityManager is active. Java7: JAXP properties may need to be used to disable external access. See http://docs.oracle.com/javase/tutorial/jaxp/properties/properties.html Java6 and earlier: A new system property org.apache.taglibs.standard.xml.accessExternalEntity may be used to specify the protocols that can be used to access external entities. This defaults to "all" if no SecurityManager is present and to "" (thereby disabling access) if a SecurityManager is detected.
