CVE-2022-30638

Code execution via out-of-bounds font write

Published Sep 7, 2023 · Updated Feb 27, 2025

An out-of-bounds write in Adobe Illustrator 26.0.2 and earlier and 25.4.5 and earlier allows remote attackers to execute code via a malicious file. The embedded-font parser fails to validate user-supplied font data before writing it, causing memory corruption outside the intended buffer. Exploitation requires the victim to open the crafted file, and resulting code runs in the current user's process context.
