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 13.0.0.302 and 14.x through 18.x before 18.0.0.203 on Windows and OS X and before 11.2.202.481 on Linux, Adobe AIR before 18.0.0.180, Adobe AIR SDK before 18.0.0.180, and Adobe AIR SDK & Compiler before 18.0.0.180 allow attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2015-3117, CVE-2015-3123, CVE-2015-3130, CVE-2015-3133, CVE-2015-3134, and CVE-2015-4431.

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 allows remote attackers to execute arbitrary code or cause denial of service via unspecified vectors, leading to memory corruption. This was one of multiple Flash Player zero-days leaked from the Hacking Team and has a CVSS score of 10 (Critical).

MitigationUpdate Adobe Flash Player to version 18.0.0.203 or later (14.x-18.x), 13.0.0.302 or later (13.x), or 11.2.202.481 or later (Linux). Update Adobe AIR to 18.0.0.180 or later. Consider disabling Flash if updates cannot be applied.

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 browsers
    Visit 'about:flash' in Chrome/Opera, 'about:plugins' in Firefox, or check the plugin via chrome://plugins. Look for the version number listed for the Flash plugin.
    Affected if The installed version is 13.0.0.289 or earlier, OR any of these specific 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 Linux
    Run 'rpm -q flash-player' or 'dpkg -l | grep flash' on Linux systems to retrieve the installed Flash package version.
    Affected if The version is 11.2.202.460 or earlier on Linux (OpenSUSE Evergreen 11.4 is specifically listed as affected).
  3. Check Adobe AIR version on Windows
    Open Control Panel > Programs and Features, or run 'msiexec /x' to see installed AIR version. The AIR installer typically stores version info in the registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Adobe AIR.
    Affected if The installed Adobe AIR version is 18.0.0.144 or earlier.
  4. Check Adobe AIR SDK version
    If AIR applications are being developed, check the SDK version by looking at the AIR SDK folder or running 'airc -version' if available. The SDK version is typically found in the AIR SDK readme or version file.
    Affected if The AIR SDK or AIR SDK & Compiler version is 18.0.0.144 or earlier.
  5. Verify Flash is enabled in browsers
    Check browser plugin settings: in Chrome/Edge go to chrome://extensions or chrome://plugins, in Firefox go to Add-ons > Plugins. Confirm the Flash plugin is set to 'Always Activate' or 'Enabled'.
    Affected if Flash Player is enabled and the version meets the affected criteria from step 1.

Your environment is affected if Adobe Flash Player (any version listed as affected or lower) or Adobe AIR (18.0.0.144 or earlier) is installed and the Flash plugin is enabled in any browser.

Upgrade available Upgrade to a release after 18.0.0.144
Interim mitigation

Update Adobe Flash Player to version 18.0.0.203 or later (14.x-18.x), 13.0.0.302 or later (13.x), or 11.2.202.481 or later (Linux). Update Adobe AIR to 18.0.0.180 or later. Consider disabling Flash if updates cannot be applied.

Recommended fix High confidence

Adobe Flash Player 18.0.0.203+ (or 13.0.0.302+ for legacy 13.x branch); Adobe AIR 18.0.0.180+; Adobe AIR SDK 18.0.0.180+

  1. Identify which Adobe product is installed (Flash Player, AIR, AIR SDK, or AIR SDK & Compiler) and note the current version
  2. For Flash Player on Windows/OS X: Upgrade to version 13.0.0.302 or later, or upgrade to version 18.0.0.203 or later for the 14.x-18.x branch
  3. For Flash Player on Linux: Upgrade to version 11.2.202.481 or later
  4. For Adobe AIR: Upgrade to version 18.0.0.180 or later
  5. For Adobe AIR SDK: Upgrade to version 18.0.0.180 or later
  6. For Adobe AIR SDK & Compiler: Upgrade to version 18.0.0.180 or later
  7. Verify the installed version matches or exceeds the fixed version after upgrade
Caveat Adobe Flash Player reached end-of-life on December 31, 2020 and should be migrated away from entirely; no further security updates will be available
