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 Adobe product installation
    On Windows, check Program Files for Adobe Acrobat or Adobe Reader folders, or use Add/Remove Programs. On Mac OS X, check /Applications for Adobe Acrobat or Adobe Reader apps.
