I agree it isn't a bug in the RNG itself, but it a bug in randomness propagation which is part of randomness generation. For instance consider this bug: secretKey = Hexadecimal(Crypto.Rand())[0:16] The person likely intended to generate a secret_key with 16 bytes of entropy. Instead they generated a secretKey which is 16 bytes long, but only contains 8 bytes of entropy. I would call this a RNG bug.
