CVE-2023-26412

Code execution via unchecked USDA data length

Published Apr 13, 2023 · Updated Mar 5, 2025

Stack-based buffer overflow in Adobe Substance 3D Designer 12.4.0 and earlier allows remote attackers to execute code via a crafted USDA file. The USDA parser copies user-supplied data into a fixed-length stack buffer without first validating its length. A victim must open the file, after which code runs with the privileges of the current Designer process.
