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
Use-after-free vulnerability in Adobe Flash Player before 18.0.0.241 and 19.x before 19.0.0.185 on Windows and OS X and before 11.2.202.521 on Linux, Adobe AIR before 19.0.0.190, Adobe AIR SDK before 19.0.0.190, and Adobe AIR SDK & Compiler before 19.0.0.190 allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2015-5570, CVE-2015-5574, CVE-2015-5581, and CVE-2015-6682.

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

A use-after-free vulnerability in Adobe Flash Player's memory management allows remote attackers to execute arbitrary code by leveraging freed memory before it is properly reallocated. This is a critical memory corruption flaw in the garbage collection or object lifecycle handling of Flash Player and AIR runtime.

MitigationUpdate Adobe Flash Player to version 18.0.0.241/19.0.0.185 (Windows/OS X) or 11.2.202.521 (Linux), and Adobe AIR to 19.0.0.190 or later. Consider migrating away from Flash as it is end-of-life.

  1. Check Adobe Flash Player version in Windows
    Open Control Panel > Programs and Features, look for Adobe Flash Player in the list, or in Internet Explorer go to Manage Add-ons > Adobe Flash Player. Also check C:\Windows\System32\Macromed\Flash for the DLL version.
    Affected if The installed version is 13.0.0.289 or earlier, OR exactly matches any of these versions: 14.0.0.125, 14.0.0.145, 14.0.0.176, 14.0.0.179, 15.0.0.152, 15.0.0.167, 15.0.0.189, 15.0.0.223, 15.0.0.239, 15.0.0.246, or 16.0.0.235
  2. Check Adobe Flash Player version on macOS
    Open System Preferences > Flash Player, or check the library location /Library/Application Support/Adobe/Flash Player for the installed version.
    Affected if The installed version matches any of the affected versions listed above for your OS version.
  3. Check Adobe AIR version on Windows
    Open Control Panel > Programs and Features, look for Adobe AIR. You can also check the version via command line by examining the properties of the Adobe AIR installer or runtime DLL in the installation directory.
    Affected if The installed version is 18.0.0.143 or earlier, OR is 18.0.0.199 or earlier.
  4. Check Adobe AIR version on macOS
    Open /Applications/Utilities/Adobe AIR Application Installer to see the version, or check /Library/Frameworks/Adobe AIR.framework for the installed version.
    Affected if The installed version is 18.0.0.143 or earlier, OR is 18.0.0.199 or earlier.
  5. Check Adobe AIR SDK version
    If you use the Adobe AIR SDK for development, check the SDK version by examining the version file or README in the SDK installation directory, typically named with the version number.
    Affected if The installed SDK version is 18.0.0.199 or earlier, OR the SDK and Compiler version is 18.0.0.180 or earlier.
  6. Check for Flash Player on Google Android
    Check if Flash Player is installed on an Android device by going to Settings > Apps and looking for Adobe Flash Player, or check the version in the app details.
