CVE-2022-24456

Code execution via crafted HEIC image rendering

Published Mar 9, 2022 · Updated Jul 8, 2025

Heap overflow in Microsoft HEVC Video Extensions affected releases allows attackers to execute code via a crafted HEIC image. Windows Imaging Component mishandles an in-memory object while rendering attacker-controlled HEIC data, causing a heap overflow. Exploitation requires a user to open or otherwise render the crafted image, after which attacker-controlled code runs in that user's security context.
