RACE Packet Validation [Seeky, Star] - Seeky - 07-04-2021 RACE Packet Validation [Seeky, Star] This code validates each section size in the header of incoming RACE packets and rejects them if they're invalid. This can act as an antifreeze and also protects against Star's RCE exploit. Also included is a check on the mii count field of the incoming USER record to prevent a buffer overflow from increasing that which could potentially be used as another RCE exploit. WARNING: If other RCE exploits were to be found, this code would do nothing to protect against them. It's specifically designed to block these two exploits.
