CVE-2024-44866Public exploitNetwork attack vector

Code execution via unchecked GuitarPro string count

Published Mar 17, 2025 · Updated Mar 19, 2025

Stack buffer overflow in MuseScore Studio 4.3.2 allows attackers to execute code or crash the application via a crafted GuitarPro file. GuitarPro1::read reads an attacker-controlled string count and copies that many integers into a seven-element tuning array without validating the count. Exploitation requires a user to open the file in the desktop application and can run code in that user's context or terminate the process.
