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 AIR allows remote attackers to execute arbitrary code via unspecified vectors. The flaw exists in the memory handling of the affected software versions, enabling attackers to overwrite memory and inject malicious code.

MitigationUpdate Adobe Flash Player to version 10.3.183.29/11.4.402.287 (Windows/Mac), 11.2.202.243 (Linux), or 11.1.115.20+ (Android); update Adobe AIR/AIR SDK to 3.4.0.2710 or later. Remove unused Flash installations.

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 Flash Player version on Windows
    Open Registry Editor and navigate to HKLM\SOFTWARE\Macromedia\FlashPlayer\Version (32-bit) or HKLM\SOFTWARE\Wow6432Node\Macromedia\FlashPlayer\Version (64-bit). Read the Version value.
    Affected if The version listed matches <= 10.3.183.25 or 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 Flash Player plugin in browsers
    In Internet Explorer, go to Tools > Manage Add-ons > Shockwave Flash Object and note the version. In Firefox, type about:plugins in the address bar and locate the Shockwave Flash entry. In Chrome, type chrome://plugins and find Flash.
    Affected if The displayed Flash Player version matches any of the vulnerable versions listed in the affected products.
  3. Check Adobe AIR version on Windows
    Open Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Adobe AIR\DisplayVersion (or look for an entry with 'Adobe AIR' in the Uninstall registry key).
    Affected if The version matches <= 3.4.0.2540 or 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, 1.5.1.8210, or 1.5.2.
  4. Check Adobe AIR SDK version
    If the AIR SDK is installed locally, locate the AIR SDK folder (commonly in C:\Program Files\Adobe or a developer SDK directory) and check the version file or the flex_sdk or air_sdk version descriptor.
    Affected if The installed AIR SDK version is <= 3.4.0.2540.
  5. Check Flash Player for Android
    On the Android device, go to Settings > Applications > Manage Applications > Adobe Flash Player and view the version information.
    Affected if The version matches <= 11.1.111.16 or any of: 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, 11.1.111.10, or <= 11.1.115.17.

If any installed version of Adobe Flash Player, Adobe AIR, Adobe AIR SDK, or Flash Player for Android matches one of the vulnerable versions or falls within the vulnerable version ranges listed in the affected products, the environment is affected by CVE-2012-5286.
