• Google assigns a CVE for libwebp and gives it a 10.0 score

  The thing that concerns me most is looking at the fix it is very difficult to see why this fix is correct. It also appears as there is lots of code without explicit bounds checks. It makes me worried because while the logic may be safe this makes the logic very complex. I wonder what the cost would be to add an explicit, local bounds check at every array access. This would serve as a backup that is much easier to verify. I suspect the cost would be relatively small. Small enough that I personally would be happy to pay it.

  This is also a great reminded that fuzzing isn't a solution to memory unsafe languages and libraries. If anything the massive amount of bugs found via fuzzing should scare us as it is likely only scratching the surface of the vulnerabilities that still lie in the code, a couple too many branches away from being likely to be found by fuzzing.

  The webp parser code is open source. Which means that even if Google decides to hide/obscure the code for webp, they'd legally not be allowed to prevent you from using older versions of the webp parser library. The only thing they could do is patent it, and then companies in the US (which has software patents, unfortunately) would have to pay royalties to decode it anyway; but here comes the next point
