CVE-2024-7993

Code execution via out-of-bounds PDF parsing

Published Oct 16, 2024 · Updated Aug 26, 2025

Out-of-bounds write in Autodesk Revit 2024 before 2024.2.2 and 2025 before 2025.3 allows attackers to execute code via a crafted PDF. The undisclosed PDF parser writes past an allocated memory boundary while processing malformed PDF content. User interaction is required; successful exploitation runs code in the current process, while failed exploitation can crash Revit or corrupt data.
