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 Adobe AIR allows attackers to execute arbitrary code via unspecified vectors. The flaw affects multiple versions across Windows, Mac OS X, Linux, and Android platforms, and is distinct from other buffer overflow CVEs in APSB12-22.

MitigationUpdate Adobe Flash Player to version 10.3.183.29 or 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); also update Adobe AIR and AIR SDK to 3.4.0.2710 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. Identify installed Adobe Flash Player version on Windows
    Open Control Panel > Programs and Features, look for 'Adobe Flash Player' or check the version via 'about:plugins' in Internet Explorer, or examine the file version of NPSWF32.dll in C:\Windows\System32\Macromed\Flash\
    Affected if The installed version matches any version listed in the CVE (specific versions or <= 10.3.183.25 for older releases)
  2. Identify installed Adobe Flash Player version on Mac OS X
    Check /Library/Application Support/Adobe/Flash Player/ for the installer receipt, or run 'ls /Library/Internet\ Plug-Ins/Flash\ Player.plugin/Contents/Info.plist' and look for CFBundleVersion, or use the Adobe Flash Player settings manager at macromedia.com
    Affected if The installed version matches any version listed in the CVE (specific versions or <= 10.3.183.25)
  3. Identify installed Adobe Flash Player version on Linux
    Check the RPM package with 'rpm -q flash-player' or 'dpkg -l | grep flash', or examine /usr/lib/flash-plugin/libflashplayer.so version info
    Affected if The installed version matches any version listed in the CVE (specific versions or <= 10.3.183.25)
  4. Identify installed Adobe Flash Player on Android
    Open Settings > Apps > Adobe Flash Player (or check the app info page) to view the version number, or use 'adb shell pm list packages' to find flash-related packages
    Affected if The installed version is <= 11.1.111.16, <= 11.1.115.17, or matches any specific version listed for Android
  5. Identify installed Adobe AIR version
    On Windows check Add/Remove Programs for 'Adobe AIR', on Mac check /Applications/Adobe AIR Installer.app, or run 'air -version' from command line if available, or examine the Adobe AIR app properties
    Affected if The installed version is <= 3.4.0.2540 or matches any specific version listed (1.0, 1.0.1, 1.0.8.4990, etc.)
  6. Identify installed Adobe AIR SDK version
    Check the AIR SDK installation directory for version file, or run 'adl -version' from the SDK bin folder, or examine the AIR SDK flex_sdk.xml or air_sdk.xml version property
    Affected if The installed AIR SDK version is <= 3.4.0.2540

A user is affected if their installed Adobe Flash Player, Flash Player for Android, Adobe AIR, or AIR SDK version matches any of the specific versions or falls at or below the upper bound versions listed in the CVE.
