dbcve analysis · high confidence

Use-after-free vulnerability in Adobe Flash Player and Adobe AIR allows attackers to execute arbitrary code via unspecified vectors. The vulnerability stems from improper memory management where memory is accessed after being freed, enabling code execution.

MitigationUpdate Adobe Flash Player to version 18.0.0.241/19.0.0.185 or later (Windows/OS X), 11.2.202.521 or later (Linux), and Adobe AIR/SDK to 19.0.0.190 or later.

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 HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Adobe Flash Player, or right-click the Flash Player DLL (npflash32.dll or Flash64_18_0_0_241.dll) in C:\Windows\System32\Macromed\Flash and select Properties to view the File Version.

  2. Check Adobe Flash Player version on Mac
    Open Terminal and run: defaults read /Library/Internet\ Plug-Ins/Flash\ Player.plugin/Contents/Info CFBundleVersion, or navigate to /Library/Internet Plug-Ins/ and right-click Flash Player.plugin to view version info.
    Affected if The version matches any of the affected versions listed in the Windows check, or is earlier than 18.0.0.241 (OS X) or 11.2.202.521 (Linux).
  3. Check Adobe AIR runtime version on Windows
    Open Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Adobe AIR, or check C:\Program Files\Adobe\Adobe AIR\Versions\1.0 folder for the AIR application files and view their version properties.
    Affected if The installed AIR version is 18.0.0.199 or earlier.
  4. Check Adobe AIR SDK version
    If using Adobe AIR for development, open the AIR SDK directory and locate the AIRSDKDescriptor.xml file, or check the version.txt file typically found in the SDK root folder.
    Affected if The AIR SDK version is 18.0.0.199 or earlier (SDK) or 18.0.0.180 or earlier (SDK & Compiler).
  5. Check for Flash Player plugin in web browsers
    In Chrome, type chrome://plugins in the address bar and look for Flash Player; in Firefox, type about:addons and select Plugins; in Internet Explorer, go to Manage Add-ons. Note the version displayed.
    Affected if The browser plugin version matches any of the affected Flash Player versions listed above.
