Adobe recommends updating your ColdFusion JDK/JRE to the latest version. Applying the ColdFusion update without a corresponding JDK update will NOT secure the server. For Application Servers Additionally, on JEE installations, set the following JVM flag, "-Djdk.serialFilter= !org.mozilla.**;!com.sun.syndication.**", 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. COLDFUSION 11 HF14 This security update requires ColdFusion to be on JDK 7u131 or JDK 8u121 or higher. Adobe recommends updating your ColdFusion JDK/JRE to the latest version.
