CVE-2013-2876
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 · uneditedbrowser/extensions/api/tabs/tabs_api.cc in Google Chrome before 28.0.1500.71 does not properly enforce restrictions on the capture of screenshots by extensions, which allows remote attackers to obtain sensitive information about the content of a previous page via vectors involving an interstitial page.
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 vulnerability exists in browser/extensions/api/tabs/tabs_api.cc in Google Chrome before 28.0.1500.71. The tabs API failed to properly enforce restrictions on screenshot capture by extensions, allowing malicious extensions to capture screenshots of sensitive content from previous web pages through interstitial page vectors.

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 the installed Google Chrome versionOpen chrome://version in the Chrome address bar, or go to Menu > Help > About Google Chrome, or run 'google-chrome --version' from the command lineAffected if The installed version is 28.0.1500.70 or lower, or exactly matches one of these versions: 28.0.1500.0, 28.0.1500.2, 28.0.1500.3, 28.0.1500.4, 28.0.1500.5, 28.0.1500.6, 28.0.1500.8, 28.0.1500.9, 28.0.1500.10, 28.0.1500.11, or 28.0.1500.12
-
Check the Debian Linux Chrome package version if running on Debian 7.0Run 'dpkg -l | grep google-chrome' or 'apt-cache policy google-chrome-stable' on the Linux systemAffected if The installed package version matches the affected Chrome versions listed above
The user is affected if they are running Google Chrome version 28.0.1500.70 or any version from 28.0.1500.0 through 28.0.1500.12 on Debian Linux 7.0, as these versions contain the tabs API vulnerability that allows extensions to capture screenshots of sensitive content from previous web pages.

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 28.0.1500.71 or later to patch the vulnerability. Organizations should inventory Chrome versions across endpoints and deploy the updated version through standard patch management processes.
