>          Components: security

>
> Receive buffer used in Kafka servers to process SASL packets is unbounded. 
> This can results in brokers crashing with OutOfMemory error when an invalid 
> SASL packet is received. 
> There is a standard SASL property in Java _javax.security.sasl.maxbuffer_ 
> that can be used to specify buffer size. When properties are added to the 
> Sasl implementation in KAFKA-3149, we can use the standard property to limit 
> receive buffer size. 
> But since this is a potential DoS issue, we should set a reasonable limit in 
> 0.9.0.1.
