Netty: Unbounded pre-allocation in RedisArrayAggregator from RESP array length

Summary RedisArrayAggregator pre-allocates ArrayList with initial capacity equal to the RESP array element count declared in an array header. That count is taken from the wire before the corresponding child messages exist. A small malicious header can claim a huge initial capacity. Details The...
