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
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 allow attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than other Flash Player memory corruption 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

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 platforms (Windows, Mac OS X, Linux, Android) and versions prior to the patched releases.

MitigationUpdate Adobe Flash Player to version 10.3.183.29+/11.4.402.287+ (Windows/Mac), 11.2.202.243+ (Linux), or 11.1.111.19+ (Android 2.x/3.x)/11.1.115.20+ (Android 4.x); also update Adobe AIR to 3.4.0.2710 or later. Alternatively, disable or remove Flash Player if unnecessary.

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
    Open a web browser and navigate to 'About Flash Player' (right-click on Flash content > 'About Adobe Flash Player'), or check the version via the Adobe version checker page at adobe.com/software/flash/about. On Windows, also check 'Add or Remove Programs' or the Flash Player plugin file properties in browser plugin directories.
    Affected if The installed version is 10.3.183.25 or lower, 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 > Apps > Adobe Flash Player, or check the version listed in the application manager. You can also check via the Adobe Flash Player settings page within the browser.
    Affected if The installed version is 11.1.111.16 or lower, or matches 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 is 11.1.115.17 or lower
  3. Check Adobe AIR version on desktop
    On Windows, open 'Add or Remove Programs' or 'Programs and Features' and look for 'Adobe AIR'. On Mac, check the version via Applications > Adobe AIR > Get Info. You can also run 'airappinstaller -version' from the command line if installed.
    Affected if The installed version is 3.4.0.2540 or lower, or matches any of: 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
    Look in the SDK installation directory for a version file or manifest, or check the 'AIR SDK Read Me' or release notes included with the SDK. The version is also often visible in the SDK folder name itself.
    Affected if The installed SDK version is 3.4.0.2540 or lower

If any installed Adobe Flash Player, Flash Player for Android, Adobe AIR, or AIR SDK version matches an affected version or falls within the affected ranges, the environment is vulnerable to CVE-2012-5252.
