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-2014-0584, CVE-2014-0585, CVE-2014-0586, 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

Adobe Flash Player and AIR suffer from a type confusion vulnerability that allows remote attackers to execute arbitrary code via unspecified vectors. The vulnerability exists in multiple product versions across Windows, OS X, and Linux platforms.

MitigationUpdate Adobe Flash Player to version 13.0.0.252 or later (14.x/15.x to 15.0.0.223 or later, Linux to 11.2.202.418 or later), and Adobe AIR/SDK to version 15.0.0.356 or later.

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 in Windows
    Open Control Panel > Programs and Features, locate Adobe Flash Player and note the version number in the 'Version' column
    Affected if Version is 11.0 through 11.2.202.417, 13.0 through 13.0.0.251, 14.0 through 14.0.0.179, or 15.0 through 15.0.0.222
  2. Check Adobe Flash Player version in macOS
    Open System Preferences > Flash Player, click the 'Storage' tab, then the 'Updates' tab to view the current version
    Affected if Version is 11.0 through 11.2.202.417, 13.0 through 13.0.0.251, 14.0 through 14.0.0.179, or 15.0 through 15.0.0.222
  3. Check Adobe Flash Player version in Linux
    Run 'rpm -q flash-plugin' or 'dpkg -l | grep flash' to query the installed package version
    Affected if Version is 11.0 through 11.2.202.417 (Linux only supports 11.x branch)
  4. Check Adobe AIR version in Windows
    Open Control Panel > Programs and Features, locate Adobe AIR and note the version number in the 'Version' column
    Affected if Version is 15.0.0.356 or earlier
  5. Check Adobe AIR version in macOS
    Open System Preferences (or Applications > Utilities) and check the Adobe AIR version in the application listing
    Affected if Version is 15.0.0.356 or earlier

You are affected if any installed Adobe Flash Player version falls within the vulnerable ranges (11.0-11.2.202.417, 13.0-13.0.0.251, 14.0-14.0.0.179, or 15.0-15.0.0.222) or if Adobe AIR/SDK version is 15.0.0.356 or earlier.

Interim mitigation

Update Adobe Flash Player to version 13.0.0.252 or later (14.x/15.x to 15.0.0.223 or later, Linux to 11.2.202.418 or later), and Adobe AIR/SDK to version 15.0.0.356 or later.

Recommended fix High confidence

Flash Player: 13.0.0.252+/14.0.0.180+/15.0.0.223+/11.2.202.418+; AIR: 15.0.0.356+; AIR SDK: 15.0.0.356+

  1. Identify which Adobe product is affected: Flash Player, AIR, AIR SDK, or AIR SDK & Compiler
  2. For Flash Player users: Determine current version (Windows/OSX or Linux) and upgrade to the fixed version for your branch: 13.0.0.252 or later (13.x), 14.0.0.180 or later (14.x), 15.0.0.223 or later (15.x), or 11.2.202.418 or later (Linux 11.x)
  3. For AIR users: Upgrade to version 15.0.0.356 or later
  4. For AIR SDK users: Upgrade to version 15.0.0.356 or later
  5. For AIR SDK & Compiler users: Upgrade to version 15.0.0.356 or later
  6. Close all browser instances and applications using Flash Player before installing the update
  7. Download the updated version from the official Adobe security bulletin (APSB14-24) at adobe.com
  8. Install the updated Flash Player or AIR version
Caveat Flash Player 11.x branch is discontinued on Windows/OSX - users must migrate to 13.x or later; some legacy content may require testing for compatibility with newer Flash versions
