Sylvain Lebresne resolved CASSANDRA-4731.
-----------------------------------------

       Resolution: Fixed
    Fix Version/s: 1.2.0 rc1

I've made the binary protocol does that kind of validation and made it more resilient to client sending bad stuff in general in commit e27a9558737f4f0d18104fd57169f681bcfc1703.

> The current implementation of CASSANDRA-2478 does very little validation of its input. At a minimum, it should validate that the header bytes are all correct types, and validate that the frame as a whole doesn't exceed the max message length as specified in the header. As soon as it sees an invalid frame, it should return an error to the client and close the connection.
