Code execution via crafted PDF heap overflow
Published Apr 15, 2025 · Updated Feb 26, 2026
Heap-based overflow in Autodesk desktop products allows attackers to execute code by importing or linking a crafted PDF file. Autodesk has not disclosed the affected PDF parser or the specific operation that writes beyond its heap allocation. Exploitation requires local user interaction and runs in the current process, enabling a crash, sensitive-data reads, or arbitrary code execution.
