Code execution via ImageIO SGI integer overflow
Published Feb 11, 2026 · Updated Feb 11, 2026
Integer overflow in Apple ImageIO before the listed 2026 updates allows attackers to execute code by processing a malicious SGI image. The SGI parser insufficiently validates image-controlled values, allowing an integer overflow before a memory write. Exploitation requires a user or application to process the crafted image and runs code in the context of the affected process.
