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
Trimble SketchUp Viewer SKP File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Trimble SketchUp Viewer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of SKP files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-21784.

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

An out-of-bounds write vulnerability exists in Trimble SketchUp Viewer's SKP file parsing due to insufficient validation of user-supplied data. The lack of proper bounds checking allows writing past the end of an allocated buffer, enabling remote code execution in the context of the current process. Exploitation requires user interaction via a malicious SKP file.

MitigationAvoid opening untrusted or unverified SKP files until an official patch is available. Apply vendor-supplied security updates promptly.

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. Identify installed SketchUp Viewer version
    Open SketchUp Viewer and navigate to Help > About SketchUp, or check the application version in the Windows Programs and Features / macOS Applications list
    Affected if The version shown is below 23.2.101 or 23.2.102 (depending on your release branch)
  2. Confirm the application processes SKP files
    Verify that the SketchUp Viewer installation includes SKP file association or that you can open .skp files through the viewer
    Affected if SKP file handling is enabled and the viewer can open model files
  3. Check for recent SKP file opening activity
    Review recently opened files in the application (File > Recent Files) or examine browser/download history if using the web viewer version
    Affected if Untrusted or unverified SKP files have been opened recently
  4. Verify patch availability from vendor
    Check Trimble's official support or update mechanism within SketchUp Viewer for available security updates
    Affected if No security update has been applied and the running version remains in the affected range

You are affected if SketchUp Viewer is installed with a version lower than 23.2.101 or 23.2.102 and the application processes or has processed SKP files.
