Heap data disclosure via IFF interleaving
Published Dec 23, 2022 · Updated Apr 15, 2025
Information disclosure in OpenImageIO 2.4.4.2 allows attackers to leak heap data via crafted ImageOutput objects. The IFFOutput channel-interleaving path mishandles specially crafted ImageOutput state and returns heap contents beyond the intended image data. Processing attacker-supplied images is required, and the consequence is confidentiality loss through disclosure of process memory rather than code execution or service interruption.
