How are zlib, gzip and zip related? What do they have in common and how are they different?
A faster zlib fork is available in https://github.com/cloudflare/zlib but it's not rebased on top of the latest upstream and is not packaged for debian.

CVE-2023-4863: Heap buffer overflow in WebP (Chrome)
So the real issue here is that the lack of tree validation before the tree construction, I believe. I'm surprised that this check was not yet implemented (I actually checked libwebp to make sure that I was missing one). Given this blind spot, an automated test based on the domain knowledge is likely useless to catch this bug.

Notes: Advanced Node.js Concepts by Stephen Grider
In the source code of the Node.js opensource project, lib folder contains JavaScript code, mostly wrappers over C++ and function definitions. On the contrary, src folder contains C++ implementations of the functions, which pulls dependencies from the V8 project, the libuv project, the zlib project, the llhttp project, and many more - which are all placed at the deps folder.
