ColdFusion JDK Requirement COLDFUSION 2018 HF1 and above For Application Servers On JEE installations, set the following JVM flag, "-Djdk.serialFilter= ! org.mozilla.**;!com.sun.syndication.**;!org.apache.commons.beanutils.**", in the respective startup file depending on the type of Application Server being used. For example: Apache Tomcat Application Server: edit JAVA_OPTS in the "Catalina.bat/sh" file WebLogic Application Server: edit JAVA_OPTIONS in the "startWeblogic.cmd" file WildFly/EAP Application Server: edit JAVA_OPTS in the "standalone.conf" file Set the JVM flags on a JEE installation of ColdFusion, not on a standalone installation. COLDFUSION 2016 HF7 and above This security update requires ColdFusion to be on JDK 8u121 or higher. Adobe recommends that you must manually update your ColdFusion JDK/JRE to the latest version. In case you do not update the JDK/JRE, simply applying the update would NOT secure the server. For Application Servers Additionally, on JEE installations, set the following JVM flag, "-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**;! org.apache.commons.beanutils.**", in the respective startup file depending on the type of Application Server being used. For example: On Apache Tomcat Application Server, edit JAVA_OPTS in the "Catalina.bat/sh" file On WebLogic Application Server, edit JAVA_OPTIONS in the "startWeblogic.cmd" file On a WildFly/EAP Application Server, edit JAVA_OPTS in the "standalone.conf" file Set the JVM flags on a JEE installation of ColdFusion, not on a standalone installation - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
