CVE-2016-5150
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 · uneditedWebKit/Source/bindings/modules/v8/V8BindingForModules.cpp in Blink, as used in Google Chrome before 53.0.2785.89 on Windows and OS X and before 53.0.2785.92 on Linux, has an Indexed Database (aka IndexedDB) API implementation that does not properly restrict key-path evaluation, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted JavaScript code that leverages certain side effects.
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 use-after-free vulnerability in the IndexedDB API implementation in Blink/Chrome allows crafted JavaScript code to improperly evaluate key-paths, leading to memory corruption. The vulnerability stems from insufficient restrictions on key-path evaluation in V8BindingForModules.cpp, which can be triggered through specific side effects in JavaScript code.

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.
-
Identify installed Chrome or Chromium browserOpen chrome://settings/help or run 'google-chrome --version' or 'chromium --version' in terminalAffected if No Chrome/Chromium browser is found on the system, the user is not affected by this browser vulnerability
-
Check Chrome version against affected rangeExamine the reported version number from chrome://settings/help or command line outputAffected if Version is 52.0.2743.116 or earlier (e.g., 51.x, 50.x, etc.)
-
Verify IndexedDB usage contextReview web applications or browser extensions that utilize IndexedDB API, particularly those evaluating key-paths dynamicallyAffected if The user runs web applications that trigger specific side effects in IndexedDB key-path evaluation (this is a JavaScript-triggered condition in the browser)
The user is affected if Google Chrome or Chromium version 52.0.2743.116 or earlier is installed and web pages using IndexedDB with specific key-path evaluation side effects can be loaded.

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 53.0.2785.89 or later (Windows/OS X) or 53.0.2785.92 or later (Linux). For web applications, review and sanitize any IndexedDB usage that could trigger the vulnerable key-path evaluation side effects.
