remote DoS in async DNS code
Greetings,
A bug exists in the label pointer handling of Tor's async DNS code that results in denial of service. A pointer loop, resulting from a pointer that points to itself or pointers that pointer to each other, will cause the parsing code to enter an endless loop.
This bug is present in Adam Langley's implementation and also in the version included in libevent.
Regards, Jon Oberheide
