CVE-2016-1687
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 renderer implementation in Google Chrome before 51.0.2704.63 does not properly restrict public exposure of classes, which allows remote attackers to obtain sensitive information via vectors related to extensions.
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 confidenceThe Chrome renderer implementation before version 51.0.2704.63 improperly exposes internal classes to extensions, allowing extension-based attack vectors to leak sensitive information from the renderer process.

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 installed Google Chrome versionOpen Chrome, go to chrome://settings/help, or run 'google-chrome --version' or 'chromium --version' from command lineAffected if Version is 50.0.2661.102 or earlier (any version <= 50.0.2661.102)
-
Verify if running on affected Debian versionCheck /etc/debian_version file or run 'cat /etc/os-release' to confirm Debian 8.0Affected if System is Debian 8.0 and Chrome <= 50.0.2661.102 is installed
-
Verify if running on affected RHEL/CentOS versionRun 'cat /etc/redhat-release' to check if version 6.0Affected if System is RHEL 6.0 (or CentOS 6.0 equivalent) and Chrome <= 50.0.2661.102 is installed
-
Verify if running on affected openSUSE versionRun 'cat /etc/os-release' to check version 42.1 or 13.2Affected if System is openSUSE 42.1 or 13.2 and Chrome <= 50.0.2661.102 is installed
-
Verify if running on affected SUSE Linux Enterprise versionRun 'cat /etc/os-release' to check if version 12.0Affected if System is SUSE Linux Enterprise 12.0 and Chrome <= 50.0.2661.102 is installed
-
Confirm extension framework is accessibleCheck if Chrome extensions can be installed or are enabled by navigating to chrome://extensions/Affected if Extensions are enabled or can be installed in the browser
You are affected if Google Chrome version is 50.0.2661.102 or earlier on any of the listed Linux distributions (Debian 8.0, RHEL 6.0, openSUSE 42.1/13.2, or SLE 12.0), especially when the extension framework is accessible.

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 51.0.2704.63 or later to remediate the class exposure vulnerability in the renderer.
