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.
-
Verify Adobe Substance 3D Designer is installedCheck for the application in the Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ for an entry named 'Adobe Substance 3D Designer', or look in C:\Program Files\Adobe\ or C:\Program Files (x86)\Adobe\ for the Substance 3D Designer folder.Affected if No entry or folder found means the product is not installed and the CVE does not apply.
-
Determine the installed version numberOpen Windows Registry and navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{ProductGUID} for Adobe Substance 3D Designer, then read the 'DisplayVersion' value; alternatively, right-click the executable in the install directory and select Properties to view the Version tab.Affected if The displayed version is 15.1.0 or any earlier version, indicating the installation is within the affected range.
-
Confirm the vulnerable file-handling component is in useThis vulnerability is triggered when the application opens a specially crafted file; no additional configuration check is needed as the flaw exists in the core file-parsing functionality of affected versions.Affected if The application is installed at an affected version and can be used to open files, meaning the out-of-bounds write vulnerability is present.
The environment is affected if Adobe Substance 3D Designer version 15.1.0 or earlier is installed and operational.

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.
From vendor dataAvoid opening files from untrusted or unknown sources until Adobe releases an official patch; update to the patched version once available.
