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 Read 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 read 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-21799.

dbcve analysis · high confidence

Out-of-bounds read vulnerability in Trimble SketchUp Viewer's SKP file parser. The lack of proper validation of user-supplied data during file parsing allows reading past the end of an allocated buffer, which can be leveraged for remote code execution in the context of the current process.

MitigationDo not open untrusted or malicious SKP files. Apply vendor patches from Trimble when available and keep SketchUp Viewer updated.

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. Check if SketchUp Viewer is installed
    Look for SketchUp Viewer in the installed programs list. On Windows, check 'Programs and Features' or search for 'SketchUp' in the start menu. On macOS, check the Applications folder.
    Affected if SketchUp Viewer is found on the system
  2. Determine the installed SketchUp Viewer version
    Right-click the SketchUp Viewer application and select 'Properties', then check the 'Details' tab for the version information. Alternatively, open SketchUp Viewer and go to Help > About SketchUp Viewer.
    Affected if Version cannot be determined or is earlier than 23.2.101 (or 23.2.102 depending on the release branch)
  3. Compare your version against affected ranges
    If version is found, verify it against the affected ranges: versions earlier than 23.2.101 or earlier than 23.2.102 are vulnerable.
    Affected if Installed version is less than 23.2.101 or less than 23.2.102
  4. Assess file handling exposure
    Determine if SketchUp Viewer is used to open SKP files from untrusted or external sources, such as email attachments, downloads, or shared network locations.
    Affected if The application processes SKP files from untrusted sources

You are affected if SketchUp Viewer is installed with a version earlier than 23.2.101 (or 23.2.102) and the application is used to open SKP files from untrusted or external sources.
