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 · uneditedSubstance3D - Sampler versions 5.0 and earlier are affected by an out-of-bounds write vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
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 confidenceOut-of-bounds write vulnerability in Substance3D Sampler versions 5.0 and earlier allows arbitrary code execution when a user opens a malicious file, due to improper bounds checking when processing file data.

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.
-
Check if Adobe Substance 3D Sampler is installedOn Windows, search for 'Adobe Substance 3D Sampler' in the Start menu or check C:\Program Files\Adobe for the application folder. On macOS, verify the application exists in /Applications/Adobe Substance 3D Sampler.app.Affected if If the application is found on the system, proceed to version check
-
Determine the installed version numberOn Windows, navigate to the Sampler installation directory, right-click the Sampler executable, select Properties, then view the Version field. Alternatively, open Command Prompt and run: wmic product where "name like '%Substance%'" get name,versionAffected if A version number is displayed - compare this to the affected range
-
Compare version against the affected rangeCheck if the installed version is below 5.0.3. Any version 5.0, 5.0.1, 5.0.2, or any version earlier than 5.0 falls within the vulnerable range.Affected if If the version is less than 5.0.3, the environment is affected by this CVE
The environment is affected if Adobe Substance 3D Sampler is installed and the installed version is lower than 5.0.3.

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 · scoped5.0.3
Update Substance3D Sampler to a version beyond 5.0 when the patch is released; until then, avoid opening files from untrusted sources.
5.0.3
- Open Adobe Creative Cloud desktop application and navigate to the 'Apps' section
- Find 'Substance 3D Sampler' in the list of installed applications
- Click on the 'Update' button next to Substance 3D Sampler if an update is available
- Alternatively, open Substance 3D Sampler and go to Help > Check for Updates
- Download and install version 5.0.3 or later
- Restart the application after updating
- Verify the updated version by checking Help > About Substance 3D Sampler
