> There have been a few reports of Kafka clients throwing an OOM because they read 4 bytes from the stream and then use that to allocate a ByteBuffer without validating that they are using the right security protocol or even communicating with a Kafka broker.
> It would be good to perform some validation in order to show a useful error message to the user instead of the OOM.
