you should update all security updates, reliably, periodically, regardless of HN posts.
you're probably not directly vulnerable for this very vuln, but then again, maybe you are. with enough vulns it gets complex enough to check that its easier to just update with all the security updates..
We just updated our scanner and included this CVE. You can run Detectify to see if your setup is vulnerable. We offer a recurring service that runs continuously and alerts you if you are exposed to new emerging vulnerabilities. This removes some of the complexity of always being on top of security alerts.
