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

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 Adobe Flash Player version on Windows or Mac
    Open a browser and visit Adobe's version check page at https://helpx.adobe.com/flash-player.html, or open the Flash Player Settings Manager at macromedia.com/support/flashplayer/sys/settings.html. Alternatively, check Add/Remove Programs (Windows) or Applications folder (Mac) for installed Flash versions.
    Affected if Installed version is 10.3.183.25 or earlier; or exactly matches any of these: 10.1.85.3, 10.1.102.64, 10.2.152.26, 10.2.152.32, 10.2.153.1, 10.2.159.1, 10.3.181.14, 10.3.181.16, 10.3.181.22, 10.3.181.26, or 10.3.181.34.
  2. Check Adobe Flash Player version on Linux
    On Linux, check the version by examining the installed package: rpm -q flash-plugin (Red Hat/CentOS) or dpkg -l | grep flash (Debian/Ubuntu). Alternatively, open a browser and use the Adobe version checker.
    Affected if Installed version is 10.3.183.25 or earlier; or exactly matches any of the Linux-affected versions listed in the advisory.
  3. Check Adobe Flash Player for Android version
    On the Android device, go to Settings > Apps > Adobe Flash Player to view the installed version, or check the app info screen for the version number.
    Affected if Installed version is 11.1.111.16 or earlier; or exactly matches any of: 10.1.106.17, 10.2.157.51, 10.3.186.7, 11.0.1.153, 11.1.102.59, 11.1.111.5, 11.1.111.7, 11.1.111.8, 11.1.111.9, 11.1.111.10, or 11.1.115.17 or earlier.
  4. Check Adobe AIR desktop runtime version
    On Windows, go to Control Panel > Programs and Features (or Add or Remove Programs) and look for Adobe AIR. On Mac, check /Library/Application Support/Adobe AIR/Versions/ or use the Adobe AIR Settings Manager in the system preferences. Run 'airpkg -info' if the AIR SDK tools are available.
    Affected if Installed version is 3.4.0.2540 or earlier; or exactly matches any of: 1.0, 1.0.1, 1.0.8.4990, 1.0.4990, 1.1, 1.1.0.5790, 1.5, 1.5.0.7220, 1.5.1, or 1.5.1.8210.
  5. Check Adobe AIR SDK version
    Navigate to the AIR SDK installation directory and open the readme.txt or version.txt file, or run 'airpkg -version' if available from command line tools. Check the SDK's release notes for version information.
    Affected if Installed SDK version is 3.4.0.2540 or earlier.

A system is affected if any installed Adobe Flash Player, Adobe AIR, or Adobe AIR SDK version matches one of the specific affected versions listed in the CVE or falls at or below the upper-bound affected version numbers.
