CVE-2022-34245

Code execution via unchecked embedded-font length

Published Jul 15, 2022 · Updated Apr 23, 2025

Heap-based buffer overflow in Adobe InDesign 17.2.1 and earlier and 16.4.1 and earlier allows attackers to execute code via a malicious file. The embedded-font parser copies user-supplied data into a fixed-length heap buffer without validating its length. Execution requires a victim to open the file, and resulting code runs in the context of the current user.
