CVE-2025-21134

Arbitrary code execution via crafted-file underflow

Published Jan 14, 2025 · Updated Feb 26, 2026

Integer underflow in Adobe Illustrator on iPad 3.0.7 and earlier allows attackers to execute code through a malicious file. Adobe has not disclosed the affected file parser or the arithmetic operation that underflows while processing attacker-controlled file data. A victim must open the file, and successful exploitation runs code in the current user's context.
