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.

Searching Compressed Space
And that links to https://www.7-zip.org/sdk.html , in the download there see the DOC folder for documentation? I really can't figure out how that somehow 'sends you back to python's lzma'...
What are some alternatives?
When comparing ZLib and LZMA you can also consider the following projects:
zlib-ng - zlib replacement with optimizations for "next generation" systems.
brotli - Brotli compression format
zstd - Zstandard - Fast real-time compression algorithm
Snappy - A fast compressor/decompressor
LZ4 - Extremely Fast Compression algorithm
