Description
We propose adding a secure coding case study for CWE-787 (Out-of-bounds Write) based on CVE-2023-4863, a widely exploited heap buffer overflow in libwebp (WebP codec).

Planned filename: c/secure-coding-case-study-cwe-787-cve-2023-4863.md
Why this is a good case study: This vulnerability impacted a widely deployed image-decoding library, was reported as exploited in the wild, and has a clear upstream patch. It provides strong prevention lessons for native-code parsers/decoders (bounds/invariant checks on derived indices, sanitizer-backed fuzzing, sandboxing/isolation, and rapid dependency updates).
