Bandit HTTP/2 Frame Size Limit Bypass via Late Buffer Check Enables Memory Exhaustion

Summary Bandit's HTTP/2 parser checks frame size after it has already buffered the full body, instead of when it sees the 9-byte header. A peer can announce a 16 MiB frame on a connection that agreed to 16 KiB frames and the server will silently buffer up to 1024× the agreed budget per connection...
