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 13.0.0.252 and 14.x and 15.x before 15.0.0.223 on Windows and OS X and before 11.2.202.418 on Linux, Adobe AIR before 15.0.0.356, Adobe AIR SDK before 15.0.0.356, and Adobe AIR SDK & Compiler before 15.0.0.356 allow attackers to execute arbitrary code by leveraging an unspecified "type confusion," a different vulnerability than CVE-2014-0577, CVE-2014-0584, CVE-2014-0585, and CVE-2014-0590.

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

Type confusion vulnerability in Adobe Flash Player and Adobe AIR allows remote attackers to execute arbitrary code via unspecified vectors. The flaw enables code execution at the privilege level of the current user, making it critically severe.

MitigationUpgrade Adobe Flash Player to version 13.0.0.252/15.0.0.223 or later (11.2.202.418 on Linux), and Adobe AIR to version 15.0.0.356 or later. Remove or disable Flash Player where possible as it has reached end-of-life.

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
    Open Registry Editor and navigate to HKLM\SOFTWARE\Macromedia\FlashPlayer (or HKLM\SOFTWARE\WOW6432Node\Macromedia\FlashPlayer on 64-bit). Read the 'Version' value. Alternatively, locate flash*.ocx in C:\Windows\System32 (or SysWOW64) and view its file version property.
    Affected if The installed version is 11.x prior to 11.2.202.418, or 13.x prior to 13.0.0.252, or 14.x up to and including 14.0.0.179, or 15.x prior to 15.0.0.223.
  2. Check Adobe Flash Player version on Linux
    Open terminal and run 'rpm -q flash-player' or check the version from the installed RPM/DEB package. On browsers, navigate to 'about:plugins' in the URL bar to see the Flash Player version listed.
    Affected if The installed version is 11.x prior to 11.2.202.418.
  3. Check Adobe AIR version on Windows
    Open Registry Editor and navigate to HKLM\SOFTWARE\Adobe\Air (or HKLM\SOFTWARE\WOW6432Node\Adobe\Air). Read the 'Version' value. Alternatively, check the file version of the AIR runtime DLL (often at C:\Program Files\Adobe\Adobe AIR\versions\Version\resources\runtime or similar).
    Affected if The installed version is 15.0.0.356 or lower.
  4. Check Adobe AIR SDK version
    If you use the AIR SDK for development, open the SDK's release notes or check the version file within the SDK directory. The SDK version is typically listed in a version.xml or release notes text file within the SDK folder.
    Affected if The SDK version is below 15.0.0.356.
  5. Confirm Flash Player is actually in use
    Open the browser and visit a site that uses Flash, or navigate to 'about:plugins' (Chrome/Firefox). If Flash is present and enabled, it is actively being used. Check if any browsers have the Flash plugin installed and enabled.
    Affected if Flash Player is installed and the browser plugin is enabled, and the version falls within the affected ranges above.

A user is affected if Adobe Flash Player (any installed version) or Adobe AIR (version 15.0.0.356 or lower) is installed and running, with versions falling within the ranges: Flash 11.x < 11.2.202.418, 13.x < 13.0.0.252, 14.x <= 14.0.0.179, 15.x < 15.0.0.223, or AIR <= 15.0.0.356.

Interim mitigation

Upgrade Adobe Flash Player to version 13.0.0.252/15.0.0.223 or later (11.2.202.418 on Linux), and Adobe AIR to version 15.0.0.356 or later. Remove or disable Flash Player where possible as it has reached end-of-life.

Recommended fix High confidence

Flash Player: upgrade to 13.0.0.252 (13.x), 14.0.0.179 (14.x), 15.0.0.223 (15.x), or 11.2.202.418 (Linux). AIR: upgrade to 15.0.0.356

  1. 1. Identify the installed Adobe Flash Player or AIR version by navigating to About Flash Player or checking the AIR version in system settings
  2. 2. Determine which version track you are on (13.x, 14.x, 15.x, or 11.x for Linux) to select the appropriate fixed release
  3. 3. Access the Adobe security bulletin APSB14-24 at helpx.adobe.com/security/products/flash-player/apsb14-24.html
  4. 4. Download the corresponding fixed version: Flash Player 13.0.0.252 (13.x track), 14.0.0.179 (14.x track), 15.0.0.223 (15.x track), or 11.2.202.418 (Linux); AIR version 15.0.0.356
  5. 5. Uninstall the current Adobe Flash Player or AIR version from the system via Control Panel/Programs and Features
  6. 6. Restart the browser or system if prompted
  7. 7. Install the downloaded fixed version of Flash Player or AIR
  8. 8. Verify the installation by checking the version number matches the patched release
Caveat Adobe Flash Player updates may affect compatibility with older SWF content or require browser restart; no major functional breaking changes expected for typical end-user scenarios
