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.

dbcve analysis · high confidence

Memory corruption vulnerability in Adobe Flash Player and Adobe AIR allows remote attackers to execute arbitrary code or cause denial of service via unspecified vectors. The flaw affects multiple versions across Windows, OS X, and Linux platforms.

MitigationUpdate Adobe Flash Player to version 13.0.0.302, 18.0.0.203 (or later 18.x), or 11.2.202.481 for Linux; update Adobe AIR and AIR SDK to version 18.0.0.180 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. Identify installed Adobe Flash Player version
    Open a web browser and navigate to 'About Flash Player' (or visit adobe.com/software/flash/about), or check the program version in Add/Remove Programs on Windows, /Applications on macOS, or /usr/lib/flash-plugin on Linux
    Affected if The version matches any of these: 11.2.202.468 or earlier (13.x branch at 13.0.0.289 or earlier, 14.x any of .125/.145/.176/.179, 15.x any of .152/.167/.189/.223/.239/.246)
  2. Identify installed Adobe AIR version
    Check the application version in Add/Remove Programs on Windows, /Applications folder on macOS, or run 'air -version' from the command line if AIR SDK is installed
    Affected if The version is 18.0.0.144 or earlier
  3. Verify if Flash Player browser plugin is active
    Open a web browser and navigate to the URL 'about:plugins' (Firefox) or 'chrome://plugins' (Chrome) to list enabled browser plugins
    Affected if Adobe Flash Player is listed as an enabled plugin with an affected version number
  4. Check for AIR applications using the vulnerable component
    Review any installed AIR applications that may process untrusted Flash content (SWF files), as the vulnerability is triggered via unspecified vectors when processing content
    Affected if AIR applications that load or process external SWF content are in use with an affected AIR version

You are affected if Adobe Flash Player version falls within the listed vulnerable ranges or Adobe AIR version is 18.0.0.144 or earlier, and the relevant plugin or AIR application is actively processing content.
