Io.netty/netty-codec-redis: netty: redisarrayaggregator nested resp headers multiply patched preallocation limits
CVSS 3.1
7.5High
Official description
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.
