Explain How log4j-1.2.15.jar and log4j-1.2.17.jar are mitigated with CF2018 Update 13

Hi. We have Adobe ColdFusion 2018 with Update 13 applied. Can you provide any documentation that explains how this patch mitigates any Log4j vulneribilites on these two log4j files:

log4j-1.2.15.jar and log4j-1.2.17.jar

C:\ColdFusion2018\cfusion\lib\log4j-1.2.15.jar

and

C:\ColdFusion2018\cfusion\jetty\lib\ext\log4j-1.2.17.jar

Thanks.
