CVE-2016-1665
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 JSGenericLowering class in compiler/js-generic-lowering.cc in Google V8, as used in Google Chrome before 50.0.2661.94, mishandles comparison operators, which allows remote attackers to obtain sensitive information via crafted 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.
-
Check Google Chrome versionNavigate to chrome://settings/help or run 'google-chrome --version' in terminal to see the installed Chrome versionAffected if Version is 50.0.2661.87 or earlier (versions before 50.0.2661.94)
-
Check V8 JavaScript engine version embedded in ChromeOpen Chrome, navigate to chrome://version, look for the V8 version string in the JavaScript engine fieldAffected if V8 version corresponds to Chrome 50.0.2661.87 or earlier releases
-
Check for V8 on Linux systems with Chromium/Chrome packagesRun 'rpm -qa | grep -i v8' or 'dpkg -l | grep -i v8' to list installed V8 packages, then run 'v8-version' or check package details for version numberAffected if V8 package version is 5.0.71.0 or earlier (the version shipped with Chrome 50.0.2661.87)
-
Identify if running Red Hat Enterprise Linux 6.x SupplementaryRun 'cat /etc/redhat-release' to confirm the OS version and 'rpm -qa | grep -i chrome' to check for installed Chrome packagesAffected if System is RHEL 6.0, 6.7, or 6.z Supplementary with Chrome version <= 50.0.2661.87
User is affected if Google Chrome version is 50.0.2661.87 or earlier, or if the embedded V8 engine version is equivalent to that Chrome release, or if RHEL 6 Supplementary has the vulnerable Chrome/V8 package installed.

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 dataUpgrade Google Chrome to version 50.0.2661.94 or later to include the patched V8 JavaScript engine.
