CVE-2016-9305
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper handling in the Autodesk FBX-SDK before 2017.1 of type mismatches and previously deleted objects related to reading and converting malformed FBX format files can allow attackers to gain access to uninitialized pointers.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Autodesk FBX-SDK before version 2017.1 contains memory corruption vulnerabilities when processing malformed FBX format files. The SDK improperly handles type mismatches and references to previously deleted objects during file parsing and conversion, leading to access of uninitialized pointers. This can be exploited remotely via malicious FBX files to potentially execute arbitrary code.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the installed FBX-SDK versionSearch for Autodesk FBX-SDK installations on the system. Check common installation directories (e.g., C:\Program Files\Autodesk\FBX or /Applications/Autodesk/FBX), or search for files named FBXSDK*.dll, libfbxsdk*.so, or FBXSDK in program directories. The version is typically embedded in the DLL/SO metadata or found in a README/version file within the SDK folder.Affected if The installed version is 2017.0 or earlier (any version <= 2017.0)
-
Identify applications using the FBX-SDKReview your software inventory for applications that import, convert, or process FBX 3D model files. Check application dependencies and runtime libraries for FBXSDK.dll (Windows), libfbxsdk.so (Linux), or libfbxsdk.dylib (macOS). Look at the application's dependency list or profiler output.Affected if An application on the system links against or loads the vulnerable FBX-SDK version and processes FBX files as part of its normal operation
-
Verify FBX file processing is enabledExamine application configuration settings, plugins, or import/export modules that handle FBX file formats. Check whether the application has active FBX import, export, or conversion features turned on, or if FBX processing is part of an automated pipeline (e.g., 3D rendering, asset management, or file conversion tools).Affected if FBX file processing features are active and the application loads the vulnerable SDK version
-
Confirm the SDK is being used for file parsingIf you have access to logs, debug output, or runtime instrumentation, verify that the FBX-SDK is actually invoked during file operations. Monitor process activity during FBX file opening, importing, or conversion to confirm the vulnerable code path (FBX document parsing and object reference handling) is being exercised.Affected if The application parses FBX files using the SDK's file reading and conversion routines, triggering the type mismatch and deleted object reference code paths
A system is affected if it runs any software using FBX-SDK version 2017.0 or earlier that parses or converts FBX files, since the memory corruption vulnerabilities in the SDK's file handling code would be triggered by malformed input.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to Autodesk FBX-SDK 2017.1 or later. Until patched, validate all FBX files before processing and consider running the SDK in sandboxed environments with memory protection mechanisms enabled.
Autodesk FBX-SDK 2017.1 or later
- Identify all applications and systems using Autodesk FBX-SDK version 2017.0 or earlier
- Download the Autodesk FBX-SDK version 2017.1 or later from the official Autodesk website
- Update the FBX-SDK library in all affected applications to version 2017.1 or later
- Rebuild and recompile any applications that link against the FBX-SDK
- Redeploy the updated applications
- Verify that the updated SDK is correctly integrated and functioning
