By inspecting the network traffic of messages to voice servers one can see
that ASCII strings are prefixed with their length as a 32-bit signed
integer. Simply modifying this to any length in excess of the actual
string's length will cause a denial of service to that voice server by
crashing it. This may be a precursor to a buffer overflow vulnerability, but
it appears not to be exploitable in this way at this time.
