Varnish Cache Project reports:

A denial of service attack can be performed on Varnish Cache servers
that have the HTTP/2 protocol turned on. An attacker can create a large
volume of streams and immediately reset them without ever reaching the
maximum number of concurrent streams allowed for the session, causing
the Varnish server to consume unnecessary resources processing requests
for which the response will not be delivered.
