CVE-2024-45311 Denial of service in quinn-proto when using `Endpoint::retry()`

Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol. As of quinn-proto 0.11, it is possible for a server to accept, retry, refuse, or ignore an Incoming connection. However, calling retry on an unvalidated connection exposes the server to a likely panic in th...
