- Possible integer overflow when handling the CONNECTION_STATE_HEADER frame - rogue server could return a malicious frame header which is then processed by the client and leads to a smaller target_size value due to integer overflow - then when the frame data is copied in via memcpy() this would overwrite past the bounds of the heap allocation, and with attacker controlled data
