It's the concept of LTS distributions to stick with one version and only patch important bugfixes and security vulnerabilities.
So if the Ubuntu security team does its job properly then you shouldn't have a reason to worry.
(However given the number of security vulns these days it's often challenging for LTS distributions to backport all security fixes. There are already breakdowns of the LTS concept, e.g. sticking with latest upstream versions for some packages like chromium where backporting is not realistic.)
