Envoy Proxy Fixes Two Zero Day vulnerabilities (UDP Proxy, TCP Proxy)

The Envoy Proxy fixed two zero day vulnerabilities, from Envoy groups : We are announcing the fixes for two zero days that were identified today: Crash in UDP proxy when datagram size is > 1500. This can happen if either MTU > 1500 or if fragmented datagrams are forwarded and reassembled: https://github.com/envoyproxy/envoy/pull/14122. This issue was already under embargo and a new issue was opened in public GitHub. Proxy proto downstream address not restored correctly for non-HTTP connections: https://github.com/envoyproxy/envoy/pull/14131. This issue was opened publicly recently but the security implications were not clear at the time. This will affect logging and network level RBAC for non-HTTP network connections.
