Re: Java, you'll need to review individual Java-based apps and add-ons--Splunk ITSI, Splunk DB Connect, etc.--for compatibility and upgrade the JRE as needed.

it's hard to say if anyone of those is directly affected to splunk, but usually it's a best practices to keep your OS and also other products up to date to avoid any security issues. You already have found Splunk's own security issue page which also should fulfil as soon as possible.
