Description

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.

CWE-416

Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
