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
Adobe Flash Player before 13.0.0.252 and 14.x and 15.x before 15.0.0.223 on Windows and OS X and before 11.2.202.418 on Linux, Adobe AIR before 15.0.0.356, Adobe AIR SDK before 15.0.0.356, and Adobe AIR SDK & Compiler before 15.0.0.356 allow attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2014-0576, CVE-2014-8440, and CVE-2014-8441.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

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 Flash Player version in Windows browsers
    Open a browser and navigate to 'about:flash' (Chrome) or 'about:plugin' (Firefox), or go to https://helpx.adobe.com/flash-player.html and check the version displayed. Alternatively, check the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion for the 'Version' value.
    Affected if The reported version is less than 13.0.0.252 (for 13.x branch), less than 15.0.0.223 (for 14.x/15.x branch), or less than 11.2.202.418 (Linux).
  2. Check Flash Player version in macOS browsers
    Open System Preferences and click on Flash Player, or navigate to /Library/Application Support/Adobe/Flash Player/ and check the version file. In Safari, enable the Develop menu and check the installed plugins.
    Affected if The reported version is less than 13.0.0.252 (for 13.x branch) or less than 15.0.0.223 (for 14.x/15.x branch).
  3. Check Flash Player version on Linux
    Run 'dpkg -l | grep flash' or 'rpm -qa | grep flash' to list installed flash-plugin packages. Also check /usr/lib/flash-plugin/ for version files or run 'flash-player-properties' to open the settings dialog showing the version.
    Affected if The reported version is less than 11.2.202.418.
  4. Check Adobe AIR version on Windows
    Open the Windows Control Panel and look for Adobe AIR in the installed programs list, or check the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\AIR\Version for the 'Version' value.
    Affected if The reported version is 15.0.0.356 or earlier.
  5. Check Adobe AIR SDK version
    Locate the AIR SDK installation directory and check the version file (typically named 'VERSION' or 'readme.txt'), or run 'adt -version' if the AIR Developer Tool is in your PATH.
    Affected if The AIR SDK version shown is 15.0.0.356 or earlier.

Your environment is affected if Adobe Flash Player is installed at any version below 13.0.0.252, 14.0.0.179, 15.0.0.223, or 11.2.202.418 (Linux), or if Adobe AIR/SDK is at version 15.0.0.356 or earlier.
