CVE-2016-5181
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 · uneditedBlink in Google Chrome prior to 54.0.2840.59 for Windows, Mac, and Linux; 54.0.2840.85 for Android permitted execution of v8 microtasks while the DOM was in an inconsistent state, which allowed a remote attacker to inject arbitrary scripts or HTML (UXSS) via crafted HTML pages.
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 confidenceA Universal Cross-Site Scripting (UXSS) vulnerability in Blink allowed v8 JavaScript microtasks to execute while the DOM was in an inconsistent state, bypassing the same-origin policy and permitting injection of arbitrary scripts or HTML into any website through crafted HTML pages.

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 checksWork through these to decide whether this CVE applies to you.
-
Check Chrome version in browserOpen a new tab and navigate to chrome://version. Look for the 'Chrome' field which displays the full version number (e.g., 53.0.2785.143).Affected if The version number displayed is 53.0.2785.143 or any version lower than 53.0.2785.143.
-
Check Chrome version via command line (Windows)Run 'reg query "HKEY_CURRENT_USER\Software\Google\Chrome\BLBeacon" /v version' in Command Prompt or PowerShell to query the installed version from the registry.Affected if The returned version value is 53.0.2785.143 or lower.
-
Check Chrome version via command line (macOS)Run '/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --version' in Terminal to display the installed version.Affected if The output shows version 53.0.2785.143 or lower.
-
Check Chrome version via command line (Linux)Run 'google-chrome --version' or 'chromium-browser --version' in Terminal to display the installed version.Affected if The output shows version 53.0.2785.143 or lower.
You are affected if the installed Google Chrome version is 53.0.2785.143 or any earlier version, since this is a version-dependent vulnerability in the Blink rendering engine.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Google Chrome to version 54.0.2840.59 or later (54.0.2840.85 for Android) to patch the vulnerability. Organizations should deploy browser updates enterprise-wide and verify completion.
