Vulnerabilities - Latest Squirro Release

Hi there,
I installed the latest squirro version and I wanted to know about the potential vulnerability / threat exposed by the following files.

Path: /usr/share/zookeeper/log4j-1.2.16.jar
Installed version : 1.2.16
Fixed version that can fix this issue : 2.16.0

Path for openJDK : /usr/share/elasticsearch/jdk/
Installed version : 17.0.1
Fixed version that can fix this issue : Upgrade to a version greater than 17.0.1

Kindly let me know the steps to redeem this issue and also so that Squirro keeps working properly. We are going to higher environments soon and I would like this thing resolved as soon as possible.
