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

Use-after-free memory corruption vulnerability in Adobe Flash Player and Adobe AIR allowing arbitrary code execution. The vulnerability exists in unspecified vectors within the affected Flash Player versions (pre-18.0.0.252/19.0.0.207 on Windows/OS X, pre-11.2.202.535 on Linux) and AIR products (pre-19.0.0.213).

MitigationUpgrade Adobe Flash Player to version 18.0.0.252 or 19.0.0.207+ (or 11.2.202.535+ on Linux), and Adobe AIR to version 19.0.0.213+. Given Flash Player end-of-life, consider removing Flash entirely if unused.

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 Windows Control Panel > Programs and Features, look for Adobe Flash Player entry, or check browser plugin list (in Chrome type chrome://plugins, in Firefox add-ons > plugins). Alternatively, check file version of npppdf.dll or flash*.ocx in system directories.
    Affected if Installed version is 11.2.202.521 or lower, or 19.0.0.185 or lower (for 19.x branch)
  2. Check Adobe Flash Player version on macOS
    Open Finder > Go > Go to Folder > /Library/Internet Plug-Ins/ and check for Flash Player plugin file info, or check browser plugin list in Safari or Chrome.
    Affected if Installed version is 11.2.202.521 or lower, or 19.0.0.185 or lower (for 19.x branch)
  3. Check Adobe Flash Player version on Linux
    Check for installed Flash package via package manager (dpkg -l | grep flash or rpm -qa | grep flash) or check /usr/lib/flash-plugin/ directory for version file.
    Affected if Installed version is 11.2.202.521 or lower
  4. Check Adobe AIR version
    Open Windows Control Panel > Programs and Features and look for Adobe AIR entry, or on macOS check /Applications/Adobe AIR folder, or check registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Adobe AIR on Windows.
    Affected if Installed version is 19.0.0.190 or lower
  5. Check Adobe AIR SDK version
    If using Adobe AIR SDK for development, check the AIR SDK version by locating the SDK directory and reading the readme or version file within it.
    Affected if Installed SDK version is 19.0.0.190 or lower

User is affected if Adobe Flash Player version is <= 11.2.202.521, <= 19.0.0.185, or Adobe AIR/SDK version is <= 19.0.0.190 on their system.

Interim mitigation

Upgrade Adobe Flash Player to version 18.0.0.252 or 19.0.0.207+ (or 11.2.202.535+ on Linux), and Adobe AIR to version 19.0.0.213+. Given Flash Player end-of-life, consider removing Flash entirely if unused.

Recommended fix High confidence

Flash Player 18.0.0.252/19.0.0.207/11.2.202.535 (Linux) and AIR 19.0.0.213 or later

  1. 1. Identify the currently installed Adobe Flash Player version by navigating to 'About Flash Player' in the right-click menu or checking Add/Remove Programs
  2. 2. Identify the currently installed Adobe AIR version via Add/Remove Programs or the AIR version checker
  3. 3. Download the fixed version from Adobe's official security bulletin APSB15-25: Flash Player 18.0.0.252 (or 19.0.0.207+ for branch 19), 11.2.202.535 for Linux; AIR 19.0.0.213 or later
  4. 4. Uninstall the current vulnerable Adobe Flash Player version via Control Panel > Programs and Features
  5. 5. Uninstall the current vulnerable Adobe AIR version via Control Panel > Programs and Features
  6. 6. Install the patched Flash Player version appropriate for your OS (Windows, OS X, or Linux)
  7. 7. Install the patched AIR SDK/SDK&Compiler version if applicable
  8. 8. Restart all browsers and applications that utilize Flash Player or AIR
Caveat Adobe Flash Player and AIR have reached end-of-life; consider migrating away from Flash-based content as Adobe ended support after December 2020
