Is the latest zero-day exploit (CVE-2021-41773) fixed in fully patched Ubuntu 20.04.3 LTS?

Question

I never understood how Ubuntu manages Apache versions, so the question: is Ubuntu 20.04.03 LTS vulnerable to the CVE-2021-41773 (a path traversal attack to map URLs to files outside the expected document root)? More info on the vulnerability:
