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
    Open Internet Explorer and navigate to 'https://helpx.adobe.com/flash-player.html' or type 'about:flash' in the address bar. Alternatively, check the registry key at HKEY_LOCAL_MACHINE\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion
    Affected if The displayed version is 11.2.202.521 or earlier, or 19.0.0.185 or earlier on the 19.x branch
  2. Check Adobe Flash Player version on macOS
    Open Safari and visit 'https://helpx.adobe.com/flash-player.html' or check the Library/Internet Plug-Ins/Flash Player.plugin file info
    Affected if The displayed version is 11.2.202.521 or earlier, or 19.0.0.185 or earlier on the 19.x branch
  3. Check Adobe Flash Player version on Linux
    Open a browser and visit 'https://helpx.adobe.com/flash-player.html', or run 'rpm -q flash-plugin' or 'dpkg -l | grep flash' depending on package manager
    Affected if The displayed version is 11.2.202.521 or earlier
  4. Check Adobe AIR version installed
    Open Control Panel (Windows) or Applications folder (macOS) and look for Adobe AIR, or run 'air -version' from command line if AIR SDK is installed
    Affected if The installed version is 19.0.0.190 or earlier
  5. Check Adobe AIR SDK or Compiler version
    If installed, check the version property of the AIR SDK folder or run 'adt -version' from the AIR SDK bin directory
    Affected if The SDK or Compiler version is 19.0.0.190 or earlier

A system is affected if any installed Adobe Flash Player version is at or below 11.2.202.521, at or below 19.0.0.185 on the 19.x branch, or any Adobe AIR/SDK version is at or below 19.0.0.190.

Interim mitigation

Update Adobe Flash Player to version 18.0.0.252 or later (19.x to 19.0.0.207 or later on Windows/OS X, 11.2.202.535 or later on Linux), and update Adobe AIR/SDK to version 19.0.0.213 or later.

Recommended fix High confidence

Flash Player: 18.0.0.252 (or 19.0.0.207 for branch 19.x, or 11.2.202.535 for Linux); Adobe AIR: 19.0.0.213; Adobe AIR SDK: 19.0.0.213; Adobe AIR SDK & Compiler: 19.0.0.213

  1. 1. Identify the installed Adobe Flash Player version by navigating to https://helpx.adobe.com/flash-player.html and checking the version information.
  2. 2. Identify the installed Adobe AIR version by checking the application's version information or using the AIR version tool.
  3. 3. For Flash Player: Download and install the appropriate fixed version from https://helpx.adobe.com/security/products/flash-player/apsb15-25.html - use version 18.0.0.252 or 19.0.0.207 (or 11.2.202.535 for Linux) depending on your branch.
  4. 4. For Adobe AIR: Download and install Adobe AIR version 19.0.0.213 or later from the Adobe website.
  5. 5. For Adobe AIR SDK/SDK & Compiler: Download and install AIR SDK version 19.0.0.213 or later from https://www.adobe.com/devnet/air/air-sdk-download.html
  6. 6. Restart all browsers and applications that use Flash Player or AIR after installation.
  7. 7. Verify the update was successful by checking the Flash Player version at about:plugins or the Adobe version check page.
Caveat Flash Player 18.x and 19.x require a browser restart and may require re-enabling the plugin in some browsers; ensure browser compatibility with the new Flash version
