Process-memory disclosure via ImageIO out-of-bounds read
Published May 8, 2023 · Updated Jan 29, 2025
An out-of-bounds read in Apple ImageIO allows context-dependent attackers to disclose process memory by supplying a crafted image. The ImageIO parser reads beyond a buffer boundary because crafted image input is not adequately validated; Apple has not identified the affected format or field. Exploitation requires a process to handle the image and exposes process memory without reported modification or service interruption.
