Process-memory disclosure via ImageIO out-of-bounds read
Published Aug 14, 2023 · Updated Oct 8, 2024
Out-of-bounds read in Apple macOS before 13.3 allows context-dependent attackers to disclose process memory by supplying an image. ImageIO reads beyond an intended buffer because image-input validation does not enforce the required bounds; Apple has not named the parser or format. The image must be processed, and the reported consequence is limited to disclosure of memory belonging to the processing application.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
