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 · unedited
Multiple buffer overflows in the Autodesk FBX-SDK before 2017.1 can allow attackers to execute arbitrary code or cause an infinite loop condition when reading or converting malformed FBX format files.

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 confidence

Multiple buffer overflow vulnerabilities exist in the Autodesk FBX-SDK versions prior to 2017.1. These flaws are triggered when the SDK reads or converts malformed FBX format files, potentially allowing remote attackers to execute arbitrary code or cause an infinite loop (denial-of-service) condition.

MitigationUpgrade to FBX-SDK version 2017.1 or later to obtain the patches. Additionally, implement strict input validation and avoid processing FBX files from untrusted sources until the upgrade is applied.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Locate FBX-SDK installations
    Search for FBX SDK files on the system: look for directories named 'FBX', 'fbx', or 'Autodesk' containing SDK files; check common installation paths like C:\Program Files\Autodesk or /usr/local/fbx; review application bundles that may embed the SDK
    Affected if FBX-SDK files are found in the environment
  2. Identify FBX-SDK version
    Check version information in SDK headers (version.h, FbxVersion.h), library files, or documentation files; the version number typically appears in the directory name (e.g., 'fbx2017', 'fbx2016') or in version resource metadata
    Affected if Installed version is 2017.0 or earlier (any version prior to 2017.1)
  3. Determine if FBX file processing is enabled
    Identify applications, services, or scripts that read, parse, or convert FBX files; review application functionality for 3D model loading, file format conversion, or FBX import capabilities; check for file handlers or plugins that process .fbx extensions
    Affected if Applications or services process FBX files using the vulnerable SDK
  4. Audit FBX file input sources
    Review where FBX files originate: user uploads, network transfers, automated pipelines, or third-party integrations; identify if untrusted or malformed FBX files could be processed
    Affected if FBX files from untrusted or external sources can be processed by affected SDK code

The environment is affected if FBX-SDK version 2017.0 or earlier is installed AND applications or services process FBX files using that SDK, enabling the buffer overflow when malformed FBX files are handled.

dbcve · scoped
Upgrade available Upgrade to a release after 2017.0
Interim mitigation

Upgrade to FBX-SDK version 2017.1 or later to obtain the patches. Additionally, implement strict input validation and avoid processing FBX files from untrusted sources until the upgrade is applied.

Recommended fix High confidence

FBX SDK 2017.1 or later

  1. 1. Identify the current version of Autodesk FBX-SDK in use by checking your project dependencies or installed files
  2. 2. Download the fixed FBX-SDK version 2017.1 or later from the official Autodesk developer website (https://www.autodesk.com/developer-network/platform-technologies/fbx-sdk)
  3. 3. Replace the vulnerable FBX-SDK library files in your project with the updated versions
  4. 4. Rebuild and recompile any applications that link against the FBX-SDK
  5. 5. Test that FBX file reading and conversion functionality works correctly with the updated library
  6. 6. Re-distribute the updated application to end users
Caveat Review the FBX SDK 2017.1 release notes for any API changes that may require code modifications
