About OpenImageIO
Every image reader is now assumed hostile, and the fuzzer proves it monthly
OpenImageIO ships on a monthly rhythm, releasing the current 3.1 line and the explicitly obsolete 3.0 line in tandem within minutes of each other. The dominant work is defensive: guarding pnm, jpeg-xl, dicom, cineon, dpx, fits and iff readers against corrupt or hostile files, with a CVE fixed in cineon bit-depth validation and a new limits:resolution attribute capping per-dimension image size against decompression bombs. libFuzzer-based fuzzing infrastructure for format readers landed in August.
