Arbitrary code execution via font parsing overflow
Published Jan 13, 2023 · Updated Mar 5, 2025
Heap-based buffer overflow in Adobe InDesign 18.0 and earlier and 17.4 and earlier allows attackers to execute code via a malicious file. The font parser overruns a heap buffer while processing attacker-controlled font data, but the affected routine and malformed structure are undisclosed. Exploitation requires a victim to open the file, and resulting code runs in the current user's context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
