Arbitrary code execution via ImageIO out-of-bounds write
Published Jun 9, 2020 · Updated Aug 4, 2024
Out-of-bounds write in Apple ImageIO in iOS, iPadOS, macOS, tvOS, watchOS, iTunes, and iCloud allows remote attackers to execute code. ImageIO performs an out-of-bounds memory write while processing image data because the affected releases apply insufficient bounds checking. Exploitation requires the affected software to process an attacker-supplied image; no authentication is required.
