CVE-2024-23286

Arbitrary code execution via ImageIO buffer overflow

Published Mar 8, 2024 · Updated Apr 2, 2026

Buffer overflow in ImageIO across Apple operating systems allows local users to execute arbitrary code by processing a crafted image. Apple identifies the affected locus as ImageIO and states that unsafe memory handling causes a buffer overflow, but has not disclosed the specific routine or malformed field. Execution requires the crafted image to be processed; code runs with the privileges of the affected process.
