CVE-2023-29283
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 · uneditedAdobe Substance 3D Painter versions 8.3.0 (and earlier) is affected by a Heap-based Buffer Overflow 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 confidenceAdobe Substance 3D Painter versions 8.3.0 and earlier contains a heap-based buffer overflow vulnerability during file parsing. An attacker can craft a malicious file that, when opened by a victim, triggers the overflow and allows arbitrary code execution in the context of the current user.

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 Painter is installedLook for the application in the system. On Windows, check Program Files or Program Files (x86) for 'Adobe Substance 3D Painter' folder. On macOS, check /Applications folder for 'Adobe Substance 3D Painter'.Affected if The application is present on the system
-
Determine the installed version of Adobe Substance 3D PainterOn Windows, open the application and go to Help > About, or check the version in the installer/registry. On macOS, right-click the app in Applications, select Get Info, and check the Version field. The version number is typically displayed in the format like 8.x.x.Affected if The version cannot be determined or is <= 8.3.0
-
Verify the file parsing feature is accessibleConfirm the application can open .spp files or project files. The vulnerability triggers during file parsing when a victim opens a maliciously crafted file.Affected if The application can open .spp or project files and the version is <= 8.3.0
A user is affected if Adobe Substance 3D Painter version 8.3.0 or earlier is installed and the application can open .spp or project files, allowing a maliciously crafted file to trigger the heap-based buffer overflow.
