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 18.0.0.252 and 19.x before 19.0.0.207 on Windows and OS X and before 11.2.202.535 on Linux, Adobe AIR before 19.0.0.213, Adobe AIR SDK before 19.0.0.213, and Adobe AIR SDK & Compiler before 19.0.0.213 allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2015-7629, CVE-2015-7631, and CVE-2015-7643.

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

Use-after-free vulnerability in Adobe Flash Player and Adobe AIR allowing remote attackers to execute arbitrary code. Affects Flash Player versions before 18.0.0.252/19.0.0.207 (Windows/OS X), before 11.2.202.535 (Linux), and AIR versions before 19.0.0.213. The vulnerability stems from improper memory management allowing freed memory to be accessed.

MitigationUpdate Adobe Flash Player to version 18.0.0.252/19.0.0.207 or later (Windows/OS X), 11.2.202.535 or later (Linux), and Adobe AIR to 19.0.0.213 or later. Given Flash's end-of-life status, consider removing Flash entirely as a long-term mitigation.

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 Windows Flash Player version
    Open Control Panel > Programs and Features, look for 'Adobe Flash Player XX' entry, or open cmd.exe and run: reg query 'HKLM\SOFTWARE\Macromedia\FlashPlayer' /v Version
    Affected if Version is 19.0.0.185 or lower, or 11.2.202.521 or lower on the 11.x branch for Linux
  2. Check macOS Flash Player version
    Open System Preferences > Flash Player, or run in Terminal: /Library/Application\ Support/Adobe/Flash\ Player/install_flash_player_osx.app/Contents/MacOS/Install\ Adobe\ Flash\ Player --dumpversion
    Affected if Version is 19.0.0.185 or lower
  3. Check Adobe AIR version on Windows
    Open Control Panel > Programs and Features, look for 'Adobe AIR' entry and note the version number
    Affected if Version is 19.0.0.190 or lower
  4. Check Adobe AIR version on macOS
    Open Terminal and run: ls /Applications | grep -i 'Adobe AIR' then check the app's Info.plist or right-click the app > Get Info to view version
    Affected if Version is 19.0.0.190 or lower
  5. Identify if Flash is actively used
    Check browsers for enabled Flash plugins: in Chrome, navigate to chrome://plugins and look for 'Shockwave Flash', or in Firefox, navigate to about:addons > Plugins
    Affected if Adobe Flash Player plugin is present and enabled with a version matching the affected ranges above

You are affected if Adobe Flash Player version is 19.0.0.185 or lower (or 11.2.202.521 or lower on Linux) OR Adobe AIR version is 19.0.0.190 or lower, and the Flash/ AIR component is installed and enabled in your environment.

Interim mitigation

Update Adobe Flash Player to version 18.0.0.252/19.0.0.207 or later (Windows/OS X), 11.2.202.535 or later (Linux), and Adobe AIR to 19.0.0.213 or later. Given Flash's end-of-life status, consider removing Flash entirely as a long-term mitigation.

Recommended fix High confidence

Flash Player: 18.0.0.252 / 19.0.0.207+ (Win/OS X), 11.2.202.535+ (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 or Adobe AIR version by navigating to 'About Flash Player' or checking the application's version information
  2. 2. For Windows/OS X Flash Player users: Upgrade to version 18.0.0.252 or 19.0.0.207 or later from the Adobe Flash Player download center
  3. 3. For Linux Flash Player users: Upgrade to version 11.2.202.535 or later
  4. 4. For Adobe AIR users: Upgrade to version 19.0.0.213 or later
  5. 5. For Adobe AIR SDK developers: Upgrade to Adobe AIR SDK 19.0.0.213 or later
  6. 6. For Adobe AIR SDK & Compiler users: Upgrade to version 19.0.0.213 or later
  7. 7. Verify the upgrade was successful by checking the version number after installation
  8. 8. Restart any browsers or applications using Flash Player to ensure the new version is loaded
Caveat Flash Player and AIR are deprecated technologies; Adobe ended support in December 2020, and modern browsers have removed Flash support - consider migrating to HTML5/Canvas/WebGL alternatives
