Red Hat Netty: denial of service
No fix yet
A flaw was found in Netty's RedisArrayAggregator component. A remote attacker can exploit this vulnerability by sending specially crafted nested Redis (RESP) array headers. This can cause the RedisArrayAggregator to eagerly preallocate a large amount of heap memory, leading to heap memory exhaustion and a Denial of Service (DoS) for applications using RedisDecoder with RedisArrayAggregator on untrusted traffic.
