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 checksWork through these to decide whether this CVE applies to you.
-
Check if Adobe Flash Player is installedOn Windows, check Program Files for Adobe Flash Player folders or check browser extensions. On Linux, use package manager (dpkg -l | grep flash or rpm -qa | grep flash) or check /usr/lib/flash-plugin. On macOS, check /Library/Internet Plug-Ins for Flash Player.Affected if Flash Player is found installed on the system
-
Determine the installed Flash Player versionOn Windows, open Flash Player in Windows Programs and Features or check the version via the Flash Player Help > About Adobe Flash Player. In browsers, navigate to about:plugins (Firefox) or chrome://plugins (Chrome) to see version. On Linux, run rpm -q flash-plugin or check the version file in the installation directory.Affected if Version cannot be determined or is 32.0.0.171 or earlier
-
Compare installed version to affected rangeCompare the discovered version number to the affected range: any version less than or equal to 32.0.0.171 is vulnerable. Note the exact version number displayed.Affected if Installed version is 32.0.0.171 or any earlier version (e.g., 32.0.0.156, 31.0.0.0, etc.)
-
Verify Flash Player is enabled in browsersCheck browser plugin settings to confirm Flash Player is enabled. In Firefox, go to Add-ons > Plugins. In Chrome, go to chrome://settings/content. In Edge, go to edge://settings/content.Affected if Flash Player is enabled and the version is within the affected range
The system is affected if Adobe Flash Player is installed with any version <= 32.0.0.171 and is enabled for use in any browser or application.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to a newer Flash Player version beyond 32.0.0.171, or preferably remove/disable Flash Player entirely since it reached end-of-life in December 2020.
