"This bug also shows that we have an over-reliance on #fuzzing for security assurance of complex parser code. Fuzzing is great, but we know that there are many serious security issues that aren't easy to fuzz. For sensitive attack surfaces like image decoding (zero-click remote #exploit attack surface), there needs to 1) be a bigger investment in proactive source code reviews, and 2) a renewed focus on ensuring these parsers are adequately sandboxed." https://blog.isosceles.com/the-webp-0day/ #libwebp #WebP
