To verify if Synergy has JRE version to address these security vulnerabilities:-
Open a command prompt
Unix:-
Go to $CCM_HOME/jre/bin folder
Execute ./java -version
Windows:-
Go to %CCM_HOME%\jre\bin folder
Execute java -version
If in the output version is greater than SR16 FP20 or if it is SR16 FP20, It implies the run area has jre version that addresses these security vulnerabilities.
