CVE-2016-1653
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 · uneditedThe LoadBuffer implementation in Google V8, as used in Google Chrome before 50.0.2661.75, mishandles data types, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that triggers an out-of-bounds write operation, related to compiler/pipeline.cc and compiler/simplified-lowering.cc.
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 data type mishandling vulnerability in Google V8's LoadBuffer implementation allows crafted JavaScript to trigger out-of-bounds write operations. The flaw exists in compiler/pipeline.cc and compiler/simplified-lowering.cc, potentially enabling remote code execution or denial of service.

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 Google Chrome versionNavigate to chrome://settings/help or run 'google-chrome --version' in terminal to see installed Chrome versionAffected if Version is 49.0.2623.112 or lower
-
Identify V8 engine version in ChromeNavigate to chrome://version in Chrome and look for the V8 version string, or visit a site that displays JavaScript engine infoAffected if V8 version corresponds to Chrome 49.0.2623.112 or lower (approximately V8 version 5.0.71.x)
-
Check if JavaScript execution is enabled in ChromeGo to chrome://settings/content/javascript to verify JavaScript toggle statusAffected if JavaScript is allowed and Chrome version is within affected range
-
For embedded V8 applications: Identify V8 library versionIf V8 is embedded in a custom application, check the application's about screen, debug info, or library version file. Run 'strings' on libv8.so or v8.dll and search for version patterns like '5.0'Affected if V8 library version is 5.0.71.x or lower and the application processes untrusted JavaScript
A user is affected if they run Google Chrome 49.0.2623.112 or lower (or an embedded V8 application with equivalent version) with JavaScript enabled, as the vulnerability requires executing crafted JavaScript code to trigger the out-of-bounds write in LoadBuffer.

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 50.0.2661.75 or later. Organizations using V8 in custom applications should update to the patched V8 version and re-test JavaScript-dependent functionality.
