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
Buffer overflow in Adobe Flash Player before 18.0.0.232 on Windows and OS X and before 11.2.202.508 on Linux, Adobe AIR before 18.0.0.199, Adobe AIR SDK before 18.0.0.199, and Adobe AIR SDK & Compiler before 18.0.0.199 allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2015-5132 and CVE-2015-5133.

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 buffer overflow vulnerability in Adobe Flash Player and AIR allows attackers to execute arbitrary code via unspecified vectors. This critical flaw affects multiple product versions across Windows, OS X, and Linux platforms, with a CVSS score of 10 indicating complete system compromise potential.

MitigationUpdate Adobe Flash Player to version 18.0.0.232 (Windows/OS X) or 11.2.202.508 (Linux), and Adobe AIR to 18.0.0.199, or preferably remove Flash entirely given its end-of-life status.

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 on Windows
    Open Registry Editor and navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion, or check the file properties of NPSWF64.dll or flash32_18_0_0_209.ocx in C:\Windows\System32\Macromed\Flash\
    Affected if The listed version is 18.0.0.209 or lower, or 11.2.202.491 or lower on Linux
  2. Check Adobe Flash Player version on Linux
    Run 'rpm -q flash-player' or 'dpkg -l | grep flash' to query installed Flash packages, or check /usr/lib/flash-plugin/ for the version file
    Affected if The installed version is 11.2.202.491 or lower
  3. Check Adobe AIR version on Windows
    Open Programs and Features (appwiz.cpl) and look for Adobe AIR, or check C:\Program Files (x86)\Adobe\AIR\versions.json for the version number
    Affected if The version listed is 18.0.0.180 or lower
  4. Check Adobe AIR SDK installation
    Look for Adobe AIR SDK in common development directories such as C:\Program Files (x86)\Adobe\AIR SDK or C:\AIR_SDK, and check the SDKDescription.xml file for the version
    Affected if The SDK version is 18.0.0.180 or lower
  5. Check for Flash plugin in browsers
    In Chrome, navigate to chrome://plugins and look for Flash; in Firefox, go to Add-ons > Plugins to list all plugin versions

  1. 1. Identify the installed Adobe Flash Player version by navigating to 'About Flash Player' in the right-click context menu or checking 'Add or Remove Programs'
  2. 2. Identify the installed Adobe AIR version from 'Add or Remove Programs' or the AIR App installed location
  3. 3. For Flash Player on Windows and OS X: Download and install Flash Player 18.0.0.232 or later from the official Adobe security bulletin (APSB15-19)
  4. 4. For Flash Player on Linux: Download and install Flash Player 11.2.202.508 or later from the official Adobe security bulletin (APSB15-19)

  7. 7. Verify the update was successful by checking the newly installed version numbers match or exceed the fixed versions listed
  8. 8. Restart any browsers or applications that use Flash Player or AIR to ensure the patched versions are loaded
Caveat Adobe Flash Player reached end-of-life on December 31, 2020; consider migrating away from Flash-based content as modern browsers have disabled or removed Flash support
