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
Buffer overflow in Adobe Flash Player before 10.3.183.29 and 11.x before 11.4.402.287 on Windows and Mac OS X, before 10.3.183.29 and 11.x before 11.2.202.243 on Linux, before 11.1.111.19 on Android 2.x and 3.x, and before 11.1.115.20 on Android 4.x; Adobe AIR before 3.4.0.2710; and Adobe AIR SDK before 3.4.0.2710 allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than other Flash Player buffer overflow CVEs listed in APSB12-22.

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

Buffer overflow vulnerability in Adobe Flash Player and Adobe AIR allowing arbitrary code execution. The vulnerability affects specific version ranges across Windows, Mac OS X, Linux, and Android platforms. This is a critical memory corruption issue that can be exploited to execute arbitrary code via unspecified vectors.

MitigationUpdate Adobe Flash Player to versions 10.3.183.29, 11.4.402.287, 11.2.202.243, 11.1.111.19, or 11.1.115.20 (platform-dependent) and Adobe AIR to 3.4.0.2710 or later. Remove or disable Flash Player where possible given its end-of-life status.

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/Mac/Linux
    Locate the Flash Player plugin in the browser or check the version via the Adobe version checker page at get.adobe.com/flashplayer. On Windows, the file npflash32.dll or npflash64.dll in the browser plugins folder often contains version metadata. Use 'reg query' on Windows or inspect the file properties of the Flash plugin binary.
    Affected if The installed version is 10.3.183.25 or earlier, or matches any of these specific versions: 10.1.85.3, 10.1.102.64, 10.2.152.26, 10.2.152.32, 10.2.153.1, 10.2.159.1, 10.3.181.14, 10.3.181.16, 10.3.181.22, 10.3.181.26, or 10.3.181.34.
  2. Check Adobe Flash Player for Android version
    On the Android device, go to Settings > Applications > Adobe Flash Player to view the installed version. Alternatively, use ADB to run 'adb shell pm list packages' to find flash-related packages, then check the package version info.
    Affected if The installed version is 11.1.111.16 or earlier, or matches any of these specific versions: 10.1.106.17, 10.2.157.51, 10.3.186.7, 11.0.1.153, 11.1.102.59, 11.1.111.5, 11.1.111.7, 11.1.111.8, 11.1.111.9, or 11.1.111.10, or falls within the range 11.1.115.17 or lower.
  3. Check Adobe AIR desktop version
    On Windows, check the installed program via Control Panel > Programs and Features, or inspect the AIR application folder. On Mac, check /Library/Application Support/Adobe/AIR or the version listed in the Air app info. The version is often displayed in the application's properties or can be queried via the AIR runtime.
    Affected if The installed version is 3.4.0.2540 or earlier, or matches any of these specific versions: 1.0, 1.0.1, 1.0.8.4990, 1.0.4990, 1.1, 1.1.0.5790, 1.5, 1.5.0.7220, 1.5.1, or 1.5.1.8210.
  4. Check Adobe AIR SDK version
    Inspect the AIR SDK installation directory. The version is typically stored in a version file or manifest within the SDK folder, or can be determined by examining the 'AIRSDKConfig.xml' or similar metadata files included with the SDK.
    Affected if The installed SDK version is 3.4.0.2540 or earlier.

A user is affected if any installed Adobe Flash Player, Flash Player for Android, Adobe AIR, or Adobe AIR SDK version matches the specific version numbers or falls within the upper-bounded version ranges listed as affected.
