User-information disclosure via out-of-bounds TIFF read
Published Dec 15, 2022 · Updated Apr 21, 2025
Out-of-bounds read in ImageIO in Apple tvOS before 16.2 allows attackers to disclose user information through a crafted TIFF file. The ImageIO parser reads beyond the intended memory boundary while processing attacker-controlled TIFF data, exposing adjacent memory contents. Exploitation requires local delivery and user interaction, and the available advisories do not identify the specific ImageIO function involved.
