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
Integer underflow in Adobe Flash Player before 11.7.700.261 and 11.8.x through 12.0.x before 12.0.0.44 on Windows and Mac OS X, and before 11.2.202.336 on Linux, allows remote attackers to execute arbitrary code via unspecified vectors.

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

Integer underflow vulnerability in Adobe Flash Player allows remote attackers to execute arbitrary code via unspecified vectors. The flaw exists in the memory handling of the Flash Player plugin across Windows, Mac OS X, and Linux platforms before the specified patched versions.

MitigationDeploy the patched Flash Player versions (11.7.700.261+, 12.0.0.44+, or 11.2.202.336+ depending on platform) or remove Flash Player if no longer required, as the CVSS 9.8 indicates trivial network exploitation with complete system compromise.

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 if Adobe Flash Player is installed
    On Windows: look in C:\Windows\System32\Macromed\Flash\ or check registry key HKLM\SOFTWARE\Macromedia\FlashPlayer. On Linux: check /usr/lib/flash-plugin/ or /usr/lib64/flash-plugin/. On Mac: check /Library/Internet\ Plug-Ins/Flash\ Player.plugin
    Affected if The Flash plugin directory or registry key exists and contains Flash files
  2. Determine the installed Flash Player version on Windows
    Open command prompt and run: reg query "HKLM\SOFTWARE\Macromedia\FlashPlayer" /v Version, or check the file version of the DLL at C:\Windows\System32\Macromed\Flash\Flash*.ocx
    Affected if The reported version matches any of the vulnerable ranges: < 11.2.202.336, < 11.7.700.261, or >= 11.8.800.94 but < 12.0.0.44
  3. Determine the installed Flash Player version on Linux
    Run: rpm -q flash-player or check the version file in the Flash plugin directory such as /usr/lib/flash-plugin/version
    Affected if The reported version matches any of the vulnerable ranges: < 11.2.202.336, < 11.7.700.261, or >= 11.8.800.94 but < 12.0.0.44
  4. Check Flash Player version in Google Chrome
    Navigate to chrome://plugins in the Chrome browser URL bar, locate the Adobe Flash Player entry, and note the version number shown
    Affected if The Flash version shown is < 32.0.1700.107 (Chrome bundles its own Flash)
  5. Check Adobe Flash Player version on Mac OS X
    Navigate to System Preferences > Flash Player > Advanced tab, or list the version in /Library/Internet\ Plug-Ins/Flash\ Player.plugin/Contents/Info.plist
    Affected if The version matches any of the vulnerable ranges: < 11.2.202.336, < 11.7.700.261, or >= 11.8.800.94 but < 12.0.0.44

A user is affected if Adobe Flash Player or the Chrome-bundled Flash is present and its version falls within any of the vulnerable version ranges listed in the CVE.

Interim mitigation

Deploy the patched Flash Player versions (11.7.700.261+, 12.0.0.44+, or 11.2.202.336+ depending on platform) or remove Flash Player if no longer required, as the CVSS 9.8 indicates trivial network exploitation with complete system compromise.

Recommended fix High confidence

Adobe Flash Player 12.0.0.44+ (Windows/Mac) / 11.2.202.336+ (Linux); Google Chrome 32.0.1700.107+; Chrome/Chromium users on Enterprise Linux should update via system package manager

  1. 1. Identify the installed Adobe Flash Player version by navigating to 'about:plugins' in the browser or checking 'Add/Remove Programs'
  2. 2. For Windows/Mac systems: Upgrade Adobe Flash Player to version 12.0.0.44 or later (or at minimum 11.7.700.261)
  3. 3. For Linux systems: Upgrade Adobe Flash Player to version 11.2.202.336 or later
  4. 4. For Google Chrome users: Upgrade Chrome to version 32.0.1700.107 or later (Chrome includes bundled Flash)
  5. 5. For Enterprise Linux systems (RHEL 5.x/6.x): Run 'yum update flash-plugin' or check Red Hat Network for applicable errata RHSA-2014:0022 or similar
  6. 6. For OpenSUSE systems: Apply security updates via 'zypper patch' or install updated flash-player packages from OpenSUSE security repositories
  7. 7. Restart all browsers and verify the Flash Player version via 'about:plugins'
Caveat Flash Player 12.x removed NPAPI support for some older systems; some legacy Flash content may require 11.7.x branch instead of 12.x
