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 Uninitialized Variable 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 initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20792.

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 uninitialized variable vulnerability exists in Trimble SketchUp Viewer's SKP file parsing logic. When processing malformed SKP files, memory is accessed before proper initialization, potentially allowing an attacker to control the uninitialized memory and achieve arbitrary code execution in the context of the current process.

MitigationDo not open untrusted or unverified SKP files. Update to the vendor patch when available. Restrict file handling to trusted sources only.

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. Verify Trimble SketchUp Viewer is installed
    Check for the presence of SketchUp Viewer application - look for 'SketchUp Viewer' in the list of installed programs (Windows: Programs and Features, macOS: Applications folder)
    Affected if SketchUp Viewer is present on the system
  2. Determine installed SketchUp Viewer version
    Open SketchUp Viewer and navigate to Help > About SketchUp Viewer, or check the version in the application's properties file
    Affected if Version number is revealed
  3. Compare version against affected ranges
    Compare your installed version to the affected ranges: < 23.2.101 or < 23.2.102
    Affected if Installed version is less than 23.2.101 or between 23.2.101 and 23.2.102 (exclusive of 23.2.102)

You are affected if Trimble SketchUp Viewer is installed and the version number is below 23.2.101 or falls between 23.2.101 and 23.2.102 (not including 23.2.102).

Interim mitigation

Do not open untrusted or unverified SKP files. Update to the vendor patch when available. Restrict file handling to trusted sources only.

Recommended fix Moderate confidence

SketchUp Viewer 23.2.102 or later

  1. 1. Close any running instances of Trimble SketchUp Viewer
  2. 2. Back up any important SKP files or projects as a precautionary measure
  3. 3. Uninstall the current version of Trimble SketchUp Viewer
  4. 4. Navigate to the official Trimble SketchUp download page or use the in-application update mechanism
  5. 5. Download and install SketchUp Viewer version 23.2.102 or later
  6. 6. Verify the installed version matches or exceeds 23.2.102
  7. 7. Test with a benign SKP file to confirm normal functionality
