Stomper 5e2741e is vulnerable to Use-After-Free. When a client sends multiple CONNECT frames on the same TCP connection, and subsequently another client (or a later connection) sends SEND frames to a destination previously subscribed on that connection, the broker may dereference a pointer to a StompStreamSocket object that has already been freed. This results in a heap use-after-free and process crash. Because the protocol does not authenticate or restrict such sequences by default.
