Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
We haven't tracked posts mentioning PhysicsFS yet.
Tracking mentions began in Dec 2020.
CVE-2023-4863: Heap buffer overflow in WebP (Chrome)
18 projects | news.ycombinator.com | 12 Sep 2023
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.

A minimal viable Deflate decompressor is not exactly complex, although slower than mainline zlib.

ZLibrary not zlib for anyone worried about archiving algorithms. https://zlib.net/ and all the Linux repositories are safe (AFAIK).
Save File Corruption fix? PLEASE HELP

>The following is my educated guess at what to do next and I am a week-end warrior programmer at best. If someone with more experience comments, I would listen to them over me< If you have no programming experience, this may be a lost cause. It looks like the save file has a header area followed by a list of "zlib" compressed chunks. zlib.net may have a program that can open the save file and let you see the raw information inside it. Something after the header is garbled and it is preventing Save-Editors from decompressing that chunk OR from parsing what is inside of it. If you are lucky, the garbled bit will jump out at you and you can repair it.
Zlib Critical Vulnerability

These appears to be the relevant changes:
The second commit definitely fixed a null pointer dereference, I am not sure if the CVE is referencing something else that was fixed by the first commit.
Gzip and Brotli Compression Level Estimator
2 projects | news.ycombinator.com | 10 Sep 2022
It is actually possible to estimate the compression level without actually compressing everything again, because different levels use different strategies which can be identified in some cases. zlib in particular has three strategies  and preflate  leverages this to store the deflate stream reconstruction data without much bits.

It's still a heap of old school C spaghetti https://github.com/madler/zlib/commit/eff308af425b67093bab25...
Faster zlib/DEFLATE decompression on the Apple M1 (and x86)

The non-forked zlib hasn't been accepting optimisations: https://github.com/madler/zlib/issues/346
Hopefully changes will be merged from my obscure private fork into four other obscure private forks (zlib-chromium (https://crbug.com/1354990), zlib-ng, zlib-cloudflare, and the one I personally care about, which doesn't take pull requests, zlib-apple), and possibly incorporated into libdeflate. That's the point of the blog post - to help maintainers understand the changes.
