COLDFUSION 2016 HF6

This security update requires ColdFusion to be on JDK 8u121 or higher. 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.
