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.

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 for Adobe Flash Player on Windows
    Open Control Panel > Programs and Features, look for 'Adobe Flash Player' entry and note the version number displayed, or run 'reg query "HKLM\SOFTWARE\Macromedia\FlashPlayer" /v Version' in Command Prompt
    Affected if version listed is 10.3.183.25 or lower, or matches any of these: 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, 10.3.181.34
  2. Check for Adobe Flash Player on Mac
    Open Safari, go to adobe.com/shockwave/welcome, or check /Library/Application Support/Adobe/Flash Player for version files, or run 'defaults read /Library/Application Support/Adobe/Flash Player'
    Affected if version is 10.3.183.25 or lower, or matches any of the specific versions listed in the affected range
  3. Check for Adobe Flash Player on Linux
    Run 'rpm -q flash-plugin' or 'dpkg -l | grep flash' in terminal to retrieve installed package version
    Affected if installed version matches the affected Flash Player versions listed
  4. Check for Adobe AIR application
    On Windows check Add/Remove programs for 'Adobe AIR' entry; on Mac check /Applications for Adobe AIR app; run 'air -version' if AIR SDK is installed
    Affected if Adobe AIR version is 3.4.0.2540 or lower, or matches any of these: 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
  5. Check for Adobe AIR SDK
    If you have Adobe AIR SDK installed, run 'air -version' or check the SDK version file in the installation directory
    Affected if AIR SDK version is 3.4.0.2540 or lower

Your environment is affected if any installed Adobe Flash Player or Adobe AIR version matches the specific version numbers or falls within the version ranges listed as vulnerable.

Upgrade available Upgrade to a release after 11.1.115.17
Interim mitigation

Update Adobe Flash Player to versions 10.3.183.29/11.4.402.287 (Windows/Mac), 11.2.202.243 (Linux), 11.1.111.19 (Android 2.x/3.x), or 11.1.115.20 (Android 4.x); update Adobe AIR to 3.4.0.2710 or later.

Recommended fix High confidence

Flash Player 10.3.183.29/11.4.402.287 (Windows/Mac), 11.2.202.243 (Linux), 11.1.111.19 (Android 2.x/3.x), 11.1.115.20 (Android 4.x); Adobe AIR 3.4.0.2710; Adobe AIR SDK 3.4.0.2710

  1. 1. Identify the currently installed Flash Player or Adobe AIR version by navigating to About Flash Player (right-click on SWF content) or checking the system's installed programs
  2. 2. Determine the appropriate fixed version based on your platform: Windows/Mac OS X users need Flash Player 10.3.183.29 or 11.4.402.287; Linux users need Flash Player 10.3.183.29 or 11.2.202.243; Android 2.x/3.x users need Flash Player 11.1.111.19; Android 4.x users need Flash Player 11.1.115.20
  3. 3. For Adobe AIR or Adobe AIR SDK, download version 3.4.0.2710
  4. 4. Download the appropriate Flash Player installer from the official Adobe website (archived versions)
  5. 5. Close all browser instances and any applications using Flash Player or AIR
  6. 6. Run the installer with administrator privileges
  7. 7. Restart the browser or application
  8. 8. Verify the installed version matches the target fixed version
Caveat Adobe ended Flash Player support on December 31, 2020 - for modern systems, removal of Flash Player is recommended rather than upgrading; some older applications may depend on specific AIR versions
