Hysteria: A specially constructed quic package can crash the server OOM when the sniff is enabled

Summary A specially constructed quic package can crash the server OOM when the sniff is enabled. Details When the server has sniff enabled, a valid connection can request the server to forward UDP traffic and construct a huge crypto length. The server will allocate memory according to this length...
