https://varnish-cache.org/security/VSV00003-mitigation.html#vsv00003-mitigation was fixed in 6.2.1 a month ago, 6.3.0 includes lots of fixes, see https://github.com/varnishcache/varnish-cache/blob/6.3/doc/changes.rst
Keeps working for me, but I'd like to get this in soon mostly because it mitigates above linked DOS attack via crafted HTTP/1 requests which cause the server to restart with a clean cache. That one patch was merged upstream (not by me); in the past Jim did not respond to my mails and I'm interested in keeping the port in good shape so swap his MAINAINER line for mine. Feedback? OK?
