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
Double free vulnerability in 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 allows attackers to execute arbitrary code via unspecified vectors.

dbcve analysis · high confidence

Double free vulnerability in Adobe Flash Player and Adobe AIR allows attackers to execute arbitrary code via unspecified vectors. The flaw exists in multiple versions across Windows, OS X, and Linux platforms.

MitigationUpdate Adobe Flash Player to version 13.0.0.252, 14.x/15.x to 15.0.0.223 (Windows/OS X), or 11.2.202.418 (Linux), and Adobe AIR to 15.0.0.356 or later.

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 in Windows
    Open Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion (32-bit) or HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Macromedia\FlashPlayer\CurrentVersion (64-bit). Read the Version value.
    Affected if The version number is 11.x lower than 11.2.202.418, or 13.x lower than 13.0.0.252, or 14.x up to and including 14.0.0.179, or 15.x lower than 15.0.0.223
  2. Check Adobe Flash Player version in browsers
    Open a browser and navigate to about:flash (Chrome) or use the Adobe version check page at https://www.adobe.com/software/flash/about/ to display the installed version.
    Affected if The displayed version matches any of the affected ranges: < 11.2.202.418, >= 13.0 but < 13.0.0.252, >= 14.0 through 14.0.0.179, >= 15.0 but < 15.0.0.223
  3. Check Adobe Flash Player version on Linux
    Locate the libflashplayer.so file (typically in /usr/lib/flash-plugin/ or /usr/lib/mozilla/plugins/) and check its file version properties, or run: rpm -q flash-plugin or dpkg -l | grep flash
    Affected if The version is < 11.2.202.418 (Linux only receives the 11.x branch updates)
  4. Check Adobe AIR runtime version on Windows
    Open Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\AIR\Version or check the version of the AIR application in Programs and Features. The version is displayed as XX.X.X.X
    Affected if The version is <= 15.0.0.356 (any version at or below this number)
  5. Check Adobe AIR SDK or Compiler version
    If you have Adobe AIR SDK installed, locate the SDK version file (typically version.xml in the SDK directory) or check the AIR SDK folder name which often includes the version number.
    Affected if The SDK or Compiler version is < 15.0.0.356

You are affected if any installed Adobe Flash Player version falls within the ranges (11.x < 11.2.202.418, 13.x < 13.0.0.252, 14.x <= 14.0.0.179, 15.x < 15.0.0.223) or if Adobe AIR/SDK is at version 15.0.0.356 or lower.

Interim mitigation

Update Adobe Flash Player to version 13.0.0.252, 14.x/15.x to 15.0.0.223 (Windows/OS X), or 11.2.202.418 (Linux), and Adobe AIR to 15.0.0.356 or later.

Recommended fix High confidence

Flash Player 13.0.0.252 (13.x), 15.0.0.223+ (14.x/15.x), or 11.2.202.418 (Linux 11.x); Adobe AIR 15.0.0.356+

  1. 1. Identify the installed Adobe Flash Player version by navigating to 'About Flash Player' in the help menu or visiting versioncheck sites
  2. 2. Identify the installed Adobe AIR version in Windows Control Panel or Mac System Preferences under Programs
  3. 3. For Flash Player: Download and install the appropriate fixed version based on your current version: 13.0.0.252 for 13.x, 15.0.0.223 or higher for 14.x/15.x, or 11.2.202.418 for Linux 11.x
  4. 4. For Adobe AIR: Uninstall the current version, then download and install Adobe AIR 15.0.0.356 or later from the official Adobe website
  5. 5. For Adobe AIR SDK/Compiler: Download and install AIR SDK 15.0.0.356 or later from the Adobe AIR SDK download page
  6. 6. Restart any browsers and verify the Flash Player version shows the patched release
  7. 7. For enterprise deployments, use Adobe's MSI installers and Group Policy for controlled rollout
Caveat This is a security-only upgrade with no expected functionality changes; however, Flash Player reached end-of-life in December 2020 and Adobe recommends migrating away from Flash-based content
