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-2014-0581, and CVE-2014-8440.

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.

dbcve analysis · high confidence

Memory corruption vulnerability in Adobe Flash Player and AIR allowing arbitrary code execution or denial of service. The flaw exists in unspecified vectors affecting multiple product versions across Windows, OS X, and Linux platforms.

MitigationApply vendor patches: update Adobe Flash Player to 13.0.0.252+ (Windows/OS X) or 11.2.202.418+ (Linux), and Adobe AIR/SDK to 15.0.0.356+. Consider Flash Player end-of-life migration if still in use.

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 Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Flash Player\InstallVersion, or check the file version of NPSWF32.dll in the System32 or SysWOW64 folder using Properties > Details
    Affected if Version is 13.0.0.0 through 13.0.0.251, 14.0.0.0 through 14.0.0.179, 15.0.0.0 through 15.0.0.222, or 11.0.0.0 through 11.2.202.417
  2. Check Adobe Flash Player version on macOS
    Navigate to /Library/Application Support/Adobe/Flash Player and inspect the version file, or right-click Flash Player.plugin in /Library/Internet Plug-Ins and select Get Info to view the version
    Affected if Version is 13.0.0.0 through 13.0.0.251, 14.0.0.0 through 14.0.0.179, 15.0.0.0 through 15.0.0.222, or 11.0.0.0 through 11.2.202.417
  3. Check Adobe Flash Player version on Linux
    Run rpm -q flash-player or dpkg -l | grep flash, or check the version of libflashplayer.so in /usr/lib/flash-plugin or /usr/share/adobe
    Affected if Version is 11.2.202.417 or earlier
  4. Check Adobe AIR version on Windows
    Open Programs and Features (or Add/Remove Programs), look for Adobe AIR in the list and note the version shown, or check the file version of AIR.exe in the Adobe AIR installation folder
    Affected if Version is 15.0.0.356 or earlier
  5. Check Adobe AIR version on macOS
    Open /Applications/Utilities/AIR Application Installer.app or check the Adobe AIR version in System Preferences or the application bundle info
    Affected if Version is 15.0.0.356 or earlier
  6. Verify Flash Player plugin is enabled in browsers
    In Internet Explorer, check Manage Add-ons for Shockwave Flash Object; in Chrome, enter chrome://plugins and locate Flash; in Firefox, enter about:addons and check Plugins section
    Affected if The Flash Player plugin is present and enabled, and its version falls within any of the affected ranges listed

If Adobe Flash Player version is 13.0.0.0-13.0.0.251, 14.0.0.0-14.0.0.179, 15.0.0.0-15.0.0.222, or 11.0.0.0-11.2.202.417 (Linux), OR Adobe AIR/SDK version is 15.0.0.356 or earlier, the environment is affected by CVE-2014-8441.

Recommended fix High confidence

Flash Player 13.0.0.252 / 14.0.0.180 / 15.0.0.223 / 11.2.202.418 (Linux); AIR/AIR SDK 15.0.0.356

  1. 1. Determine current Adobe Flash Player version by navigating to https://get.adobe.com/flashplayer/about/ or checking in system settings
  2. 2. Determine current Adobe AIR version from Windows Control Panel or Mac System Preferences
  3. 3. For Flash Player: Download and install version 13.0.0.252, 14.0.0.180, 15.0.0.223, or 11.2.202.418 (Linux) from the official Adobe Flash Player download page
  4. 4. For AIR: Download and install version 15.0.0.356 from the official Adobe AIR download page
  5. 5. Restart any browsers and verify the update by checking the version number again
  6. 6. Ensure automatic updates are enabled for future security patches
Caveat Minimal risk; security updates typically maintain backward compatibility with existing content
