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.

Quite OK Image is now my favorite asset format
A minimal viable Deflate decompressor is not exactly complex[1], although slower than mainline zlib.

Zlib alternatives?
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:
2022-07-30: https://github.com/madler/zlib/commit/eff308af425b67093bab25...
2022-08-08: https://github.com/madler/zlib/commit/1eb7682f845ac9e9bf9ae3...
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
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 [1] and preflate [2] leverages this to store the deflate stream reconstruction data without much bits.

Redis License Changed
I'm curious about something: I suppose Salvatore still owns the copyright for most of the code? The old license does include his copyright, up to 2020: https://github.com/redis/redis/blob/7.2/COPYING So I think this change couldn't have been done without his explicit consent? Or did he transferred his rights to RedisLabs or a foundation?
Redis.io no longer mentions open source.
They have still not changed meta description on their page. It still says it is open source ^^

Redis Adopts Dual Source-Available Licensing
First they break lolwut (https://github.com/redis/redis/issues/12074) and now this.
Redis Inc. is moving the https://github.com/redis/redis/ project away from the three part BSD license to a dual license using two non-OSI approved license. This comes after previous comment from them saying that "... the Redis core license, which is and will always be licensed under the 3-Clause- BSD".
> They get paid for it. Don't try to spin this as if it's someone people working on it in their spare time out of the goodness of their heart. It's just their job.
No, you can't have this both ways. I'm the main contributor from AWS, and I've worked many times on weekends because I care about open source. I like helping people, I don't need to be paid to do it. Many of the AWS folks that made changes were normal engineers that were excited to be part of Redis. https://github.com/redis/redis/pull/10419 and https://github.com/redis/redis/pull/8621 are both examples of features someone from AWS built in their free time. We're all upset about this. Not because Redis deserves to get paid, it's that they acted like they were being good stewards of the open-source community and then they changed their mind.
