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.

NVD · unedited
Integer overflow in the copyRawDataTo method in the Matrix3D class in Adobe Flash Player before 11.4.402.265 allows remote attackers to execute arbitrary code via malformed arguments.

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

Integer overflow vulnerability in the copyRawDataTo method of the Matrix3D class in Adobe Flash Player allows remote attackers to execute arbitrary code via malformed arguments. The overflow occurs when processing specially crafted data, potentially allowing memory corruption and code execution.

MitigationUpgrade Adobe Flash Player to version 11.4.402.265 or later. Given Flash's end-of-life status, organizations should prioritize removing Flash Player entirely from their environments to eliminate this and other known vulnerabilities.

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 if Adobe Flash Player is installed
    On Windows, check for NPSWF32.dll in browser plugin directories (e.g., C:\Windows\System32\Macromed\Flash\ or browser-specific paths). On Mac, check /Library/Internet Plug-Ins/Flash Player.plugin. Alternatively, check Add/Remove Programs or the browser's plugin list.
    Affected if Flash Player is found on the system
  2. Determine the installed Flash Player version
    Right-click the NPSWF32.dll file and select Properties > Details to view the File Version. Or in Windows, run 'wmic product get name,version' or check the registry key HKLM\SOFTWARE\Macromedia\FlashPlayer\CurrentVersion. For browsers, enter 'about:plugins' or navigate to the browser's Add-ons > Plugins section.
    Affected if A version number is retrieved that is lower than 11.4.402.265
  3. Compare the installed version to the affected range
    Compare the version number found in step 2 against the affected range: any version below 11.4.402.265 is vulnerable. Version 11.4.402.265 and later are patched.
    Affected if The installed version is below 11.4.402.265 (for example, 11.4.402.264, 11.3.300.268, etc.)
  4. Identify if Flash content using Matrix3D is processed
    This vulnerability is triggered through the Matrix3D class copyRawDataTo method when processing malformed arguments in SWF content. Check if any web applications, documents, or local files load Flash content (SWF files) that may exercise 3D matrix operations. This is a code-level API and does not have a simple on/off config toggle.
    Affected if Flash Player versions below 11.4.402.265 are installed AND the system processes Flash content (SWF files)

A system is affected if Adobe Flash Player version below 11.4.402.265 is installed and the system processes Flash content that triggers the Matrix3D class copyRawDataTo method.
