You don't need any user interaction. It works like any heap overflow (and even better because you can directly overwrite some function's pointers without needing help from the heap management (unlink and friends)). Because a single UDP packet can exploit the flaw, source can be spoofed and doesn't even have to be an IP/port the client has already spoken to. _______________________________________________ Full-Disclosure - We believe in it.
