USN-5474-1 fixed vulnerabilities in Varnish Cache. Unfortunately the fix for
CVE-2020-11653 was incomplete. This update fixes the problem.
Original advisory details:
It was discovered that Varnish Cache could have an assertion failure when a
TLS termination proxy uses PROXY version 2. A remote attacker could possibly
use this issue to restart the daemon and cause a performance loss.
