Code execution via malformed PDF parsing
Published Oct 3, 2022 · Updated Aug 3, 2024
A memory corruption vulnerability in Autodesk AutoCAD 2023 allows attackers to execute arbitrary code via a malicious PDF file. The PDF parser mishandles crafted input and raises an unhandled exception while processing the file, enabling crash, sensitive-data reads, or code execution in the current process. Exploitation requires a local user to open or otherwise parse the malicious PDF, and the documented impact is bounded to that process context.
