varnish regression
Details

USN-5474-1 fixed vulnerabilities in Varnish Cache. Unfortunately the fix for CVE-2020-11653 was incomplete. This update fixes the problem.

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. (CVE-2020-11653)
