USER Overflow Fix [Star]
This code validates the mii count field of incoming USER records to prevent a buffer overflow that could potentially be used as an RCE exploit.
WARNING: this code only fixes one specific overflow, it does not protect against Star's original RCE exploit and wouldn't protect against any other exploits if they were to be found. For protection against the current known exploits, you should pair this code with RACE Header RCE Protection or use RACE Packet Validation instead, which protects against both and can also act as an antifreeze (although it's a longer gecko code than the other two combined)
