KAFKA-2878: Guard against OutOfMemory in Kafka broker with invalid requests
----
> Kafka broker throws OutOfMemory exception with invalid join group request
> -------------------------------------------------------------------------
>
> Key: KAFKA-2878
> URL: https://issues.apache.org/jira/browse/KAFKA-2878
> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 0.9.0.0
> Reporter: Rajini Sivaram
> Assignee: Rajini Sivaram
> Priority: Critical
>
> Array allocation for join group request doesn't have any checks and hence can
> result in OutOfMemory exception in the broker. Array size from the request
> should be validated to avoid DoS attacks on a secure installation of Kafka.
