CVE-2023-27911

Code execution via crafted FBX file parsing

Published Apr 17, 2023 · Updated Feb 6, 2025

Heap buffer overflow in Autodesk FBX SDK 2020 and earlier allows context-dependent attackers to execute code via a malicious FBX file. Autodesk has not disclosed the affected parsing routine or the malformed field whose processing overruns a heap buffer. Exploitation requires a user or consuming application to open the file, and code runs in the context of the affected process.
