Security update

Following the previous fixes for the security vulnerabilities described in ISTIO-SECURITY-2019-003 and ISTIO-SECURITY-2019-004, we are now addressing the internal control plane communication surface. These security fixes were not available at the time of our previous security release, and we considered the control plane gRPC surface to be harder to exploit.

You can find the gRPC vulnerability fix description on their mailing list (c.f. HTTP/2 Security Vulnerabilities).

Bug fix

Fix an Envoy bug that breaks java.net.http.HttpClient and other clients that attempt to upgrade from HTTP/1.1 to HTTP/2 using the Upgrade: h2c header (Issue 16391).
