Brahma Reddy Battula commented on ZOOKEEPER-2175:
-------------------------------------------------
AFAIK Once Zk Client got session ID from ZK server, there is no check for
session id validation.. seen ZOOKEEPER-2146 which checking the only length of
the packet..
> Checksum validation for malformed packets needs to handle.
