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 if Adobe Acrobat or Reader is installed
    Open Windows Control Panel > Programs and Features, or check the registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall for entries containing 'Adobe Acrobat' or 'Adobe Reader'
    Affected if No Adobe Acrobat or Reader product is found in the system, then the system is not affected by this CVE.
  2. Locate the installed Adobe application executable
    Find the main executable. For Acrobat DC, typical path is C:\Program Files\Adobe\Acrobat DC\Acrobat\Acrobat.exe. For Reader DC, typical path is C:\Program Files\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe
    Affected if If the executable does not exist at these typical paths, the application may be installed differently or not at all.
  3. Determine the installed version number
    Right-click the executable (Acrobat.exe or AcroRd32.exe), select Properties, and view the Details tab for the Product Version field. Alternatively, open the application, go to Help > About Adobe Acrobat/Reader to see the version.
    Affected if The version displayed is within the affected ranges: 15.006.30060 to 15.006.30418, 15.008.20082 to 18.011.20040, or 17.011.30059 to 17.011.30080.
  4. Confirm the product edition matches affected variants
    Verify whether the installed product is Adobe Acrobat DC or Adobe Acrobat Reader DC, as both Classic and Continuous editions are affected. Check the product name in Help > About or in Programs and Features.
    Affected if The installed product is Adobe Acrobat DC or Adobe Acrobat Reader DC with a version that falls within the affected ranges listed above.

A system is affected if Adobe Acrobat DC or Adobe Acrobat 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.
