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.

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 Adobe AIR allowing remote attackers to execute arbitrary code or cause denial of service via unspecified vectors. This is one of multiple critical memory corruption flaws discovered in Flash Player around late 2015.

MitigationUpdate Adobe Flash Player to version 18.0.0.268 or later (20.0.0.228 for versions 19.x/20.x) and Adobe AIR to 20.0.0.204 or later. If Flash is not required, consider removing it entirely to eliminate the attack surface.

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 Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Adobe Flash Player or check the version property of npapi.dll or pepflashplayer.dll in the Flash Player installation directory (typically C:\Windows\System32\Macromed\Flash)
    Affected if The version is 18.0.0.261 or lower; or exactly 19.0.0.185, 19.0.0.207, 19.0.0.226, or 19.0.0.245; or 11.2.202.548 or lower
  2. Check macOS Flash Player version
    Open Finder, go to /Library/Internet Plug-Ins/ and right-click Flash Player.plugin to Get Info, or run 'defaults read /Library/Internet\ Plug-Ins/Flash\ Player.plugin/Contents/Info CFBundleVersion' in Terminal
    Affected if The version is 18.0.0.261 or lower; or exactly 19.0.0.185, 19.0.0.207, 19.0.0.226, or 19.0.0.245; or 11.2.202.548 or lower
  3. Check Adobe AIR version on Windows
    Open Programs and Features (or Add/Remove Programs), locate Adobe AIR in the list, and note the version shown; alternatively check the version in the AIR runtime installation directory
    Affected if The version is 19.0.0.241 or lower
  4. Check Adobe AIR SDK version
    If using the AIR SDK for development, locate the AIR SDK folder and check the version.properties or VERSION file, or run 'air-sdk-version' command if available in the SDK bin directory
    Affected if The SDK version is 19.0.0.241 or lower

You are affected if any installed Adobe Flash Player matches the vulnerable 18.x/19.x/11.2.x versions or any Adobe AIR/SDK version is 19.0.0.241 or lower.

Interim mitigation

Update Adobe Flash Player to version 18.0.0.268 or later (20.0.0.228 for versions 19.x/20.x) and Adobe AIR to 20.0.0.204 or later. If Flash is not required, consider removing it entirely to eliminate the attack surface.

Recommended fix High confidence

Adobe Flash Player 20.0.0.228+ (Windows/OS X), 18.0.0.268+ (18.x branch), 11.2.202.554+ (Linux); Adobe AIR 20.0.0.204+; Adobe AIR SDK 20.0.0.204+; Adobe AIR SDK & Compiler 20.0.0.204+

  1. Identify which Adobe product is installed: Flash Player, Adobe AIR, Adobe AIR SDK, or Adobe AIR SDK & Compiler
  2. Determine the current version of the installed Adobe product
  3. For Flash Player on Windows/OS X: upgrade to version 20.0.0.228 or later
  4. For Flash Player 18.x: upgrade to version 18.0.0.268 or later
  5. For Flash Player on Linux: upgrade to version 11.2.202.554 or later
  6. For Adobe AIR: upgrade to version 20.0.0.204 or later
  7. For Adobe AIR SDK: upgrade to version 20.0.0.204 or later
  8. For Adobe AIR SDK & Compiler: upgrade to version 20.0.0.204 or later
Caveat Adobe Flash Player and AIR have reached end-of-life and are no longer supported; consider migrating away from Flash-based applications
