Mooncake transfer engine through 0.3.13.post1 contains a denial of service vulnerability that allows unauthenticated remote attackers to block the handshake daemon by never reading replies. Attackers can send a Metadata request to the handshake RPC port and stall SocketHandShakePlugin's single listener thread in writeFully(), breaking all subsequent handshakes, metadata fetches, notify and probe requests.
