Vulnerability Title
Netty: Memory Exhaustion in RedisArrayAggregator due to Deeply Nested Arrays
Source: NVD (National Vulnerability Database)
Vulnerability Description
Netty is a network application framework for development of protocol servers and clients. In netty-codec-redis prior to versions 4.1.135.Final and 4.2.15.Final, an attacker can cause DoS by sending a crafted Redis payload with deeply nested arrays. This forces the server to allocate a massive number of state objects and collections, leading to memory exhaustion and an OutOfMemoryError. Versions 4.1.135.Final and 4.2.15.Final patch the issue.
