The Debian security team often backports patches to the version the current Debian releases shipped with to minimize the risk of the update breaking stuff. So for systems that closely track Debian, you’re probably better off checking https://security-tracker.debian.org/tracker/ if your version is vulnerable. @irvinewade kindly already provided the link for this CVE (https://security-tracker.debian.org/tracker/CVE-2021-4034).
