Scenario: a node runner decides not to upgrade to the latest version of Bitcoin Core, due to a controversial change in consensus logic. 
A vulnerability is discovered, affecting all versions of Bitcoin Core, and a hotfix is published as a minor release, on top of the most recent version. 

Question: What options are available to the node runner, to patch his older version of Bitcoin Core, so as to secure it against the vulnerability, without also upgrading to the controversial / most recent version? 

Are there any more user friendly options, besides manually merging the hotfix, and rebuilding the old version from source?
