What is CVE-2020-11612?

The ZlibDecoders in Netty versions 4.1.x prior to 4.1.46 enable attackers to cause unbounded memory allocation. By sending a large Zlib-encoded byte stream, an attacker can monopolize a server's memory resources, leading to potential denial of service as the server struggles to allocate memory for the decoding process. This vulnerability highlights the importance of maintaining updated software versions to mitigate potential risks.
