dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Adobe Substance 3D Sampler version on WindowsOpen Settings > Apps > Apps & features, locate 'Adobe Substance 3D Sampler', and view the version number listed under the product name. Alternatively, navigate to the installation directory (typically C:\Program Files\Adobe\Adobe Substance 3D Sampler), right-click the executable file, select Properties, and view the File version on the Details tab.Affected if The displayed version is any version prior to 6.0.1 (for example, 6.0.0, 5.x.x, or earlier)
-
