dbcve checks

Work through these to decide whether this CVE applies to you.

Check Adobe Flash Player version in Windows browsers

Open any browser and navigate to 'About Adobe Flash Player' (or right-click on Flash content and select 'About Adobe Flash Player'), or visit https://helpx.adobe.com/flash-player.html to detect the installed version via the browser.

Affected if The displayed version is 13.0.0.289 or earlier, any 14.x version listed (14.0.0.125/145/176/179), any 15.x version listed (15.0.0.152/167/189/223/239/246), or 16.0.0.235.
Check Adobe Flash Player version in Linux browsers

Open a terminal and run: 'dpkg -l | grep flash' (Debian/Ubuntu) or 'rpm -qa | grep flash' (Red Hat/CentOS) to list installed Flash packages, or check the browser's plugin information page.

Affected if The installed Flash Player version for Linux is 11.2.202.480 or earlier.
Check Adobe AIR desktop runtime version

On Windows, open 'Add or Remove Programs' and look for 'Adobe AIR', or on macOS check '/Applications/Utilities/Adobe AIR Installation.app'. The version is typically displayed in the application entry or can be found in the AIR application folder metadata.

Affected if The installed Adobe AIR version is 18.0.0.144 or earlier.
Check Adobe AIR SDK version

Locate the AIR SDK installation directory (commonly at 'C:\Program Files (x86)\Adobe\Adobe AIR SDK' on Windows or '/opt/air-sdk' on Linux/Mac). Open the 'VERSION' or 'readme.txt' file within the SDK folder, which contains the exact version number.

Affected if The AIR SDK version is 18.0.0.144 or earlier.
Check Adobe AIR SDK Compiler version

Look for the AIR SDK Compiler (airc) in the SDK installation under 'lib/aac' or check the compiler's version by running 'airc -version' from the command line within the SDK bin directory.

Affected if The AIR SDK Compiler version corresponds to an SDK version of 18.0.0.144 or earlier.

A user is affected if Adobe Flash Player is any of the versions listed (13.0.0.289 or lower, specific 14.x/15.x/16.x versions), or if Adobe AIR/AIR SDK/AIR SDK Compiler is version 18.0.0.144 or earlier.

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.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

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.
