Brock Noland commented on THRIFT-2660:
--------------------------------------

Nice work!! I think the 100MB max message size will work for the vast majority 
of use cases, but I do think this should be configurable. I've created 
THRIFT-2678 to track that.

> In TSaslTransport#receiveSaslMessage, we are doing two things incorrectly:
> - Not validating the status byte code.
> - Not validating the decoded payload size integer before allocating a whole 
> array with it.
> The latter especially is bad when a network security software sends a thrift 
> server port some garbage data, causing it to receive failures like:
> {code}
> java.lang.OutOfMemoryError: Java heap space
