I'm running Nginx and uWSGI on my Ubuntu 18.04.6 LTS server. I checked the version of Nginx and it's 1.14.0. The uWSGI version I'm not sure, how do I check it? And is there a reason to upgrade Nginx and uWSGI for security reasons? Is there a known security vulnerability in any of them?
If I do need to upgrade, what is the best way to upgrade them? Can I do it with sudo apt update and sudo apt upgrade? I ran both of them but it's still Nginx 1.14.0.
