CVE-2022-33889

Code execution via heap overwrite during image parsing

Published Oct 3, 2022 · Updated Aug 3, 2024

Heap-based buffer overflow in Autodesk Design Review 2018 and AutoCAD 2020 through 2023 allows attackers to execute code via images. The GIF/JPEG parser writes beyond its allocated heap buffer while processing attacker-crafted image data. Execution requires a crafted image to be opened or otherwise parsed, and resulting code runs in the context of the affected process.
