Description
Stomper 5e2741e is vulnerable to Use-After-Free. When a single client repeatedly issues SUBSCRIBE commands for the same destination over one connection and then closes that connection, the broker performs incorrect cleanup of its internal subscription structures. This results in a heap use-after-free during StompClient destruction, causing the broker process to crash. An unauthenticated client can exploit this to reliably trigger a denial of service.
