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 Adobe product
    Open Adobe Acrobat or Reader, go to Help > About Adobe Acrobat (or Reader) to display the exact version number and product name (Acrobat/Reader DC, Classic, etc.)
    Affected if Product is Adobe Acrobat DC or Adobe Acrobat Reader DC
  2. Record the version number
    Note the full version number shown in the About dialog (e.g., 15.006.30418 or 18.011.20040)
    Affected if Version falls within any of the affected ranges: 15.006.30060-15.006.30418, 15.008.20082-18.011.20040, or 17.011.30059-17.011.30080
  3. Verify the product edition
    Confirm whether the installed product is Acrobat DC or Reader DC - the affected versions listed apply specifically to the DC (Document Cloud) variants
    Affected if The product is Acrobat DC or Reader DC within the affected version ranges
  4. Compare version against affected ranges
    Check if the installed version is 2018.011.20040 or earlier, 2017.011.30080 or earlier, or 2015.006.30418 or earlier (or the DC-specific ranges noted above)
    Affected if Installed version matches or is lower than any of these three version thresholds

User is affected if Adobe Acrobat DC or Reader DC is installed with a version number within 15.006.30060-15.006.30418, 15.008.20082-18.011.20040, or 17.011.30059-17.011.30080.
