CVE-2014-7946
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 RenderTable::simplifiedNormalFlowLayout function in core/rendering/RenderTable.cpp in Blink, as used in Google Chrome before 40.0.2214.91, skips captions during table layout in certain situations, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors related to the Fonts implementation.
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 confidenceIn Blink's RenderTable::simplifiedNormalFlowLayout function in core/rendering/RenderTable.cpp, captions are incorrectly skipped during table layout in certain situations. This causes an out-of-bounds read when the Fonts implementation attempts to access memory outside the expected bounds, leading to a denial of service condition.

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.
-
Verify Google Chrome is installedCheck for Google Chrome browser on the system. On Windows, look in Program Files\Google\Chrome\Application\chrome.exe. On macOS, look in /Applications/Google Chrome.app. On Linux, run 'which google-chrome' or 'which chromium-browser'.Affected if Google Chrome is not present on the system, this CVE does not apply.
-
Determine installed Google Chrome versionOpen Google Chrome, click the menu icon (three dots), select Help, then select About Google Chrome. The version number will be displayed on that page. Alternatively, from command line run 'google-chrome --version' on Linux or '"C:\Program Files\Google\Chrome\Application\chrome.exe" --version' on Windows.Affected if This check is required to compare against the affected version range.
-
Compare version to affected rangeCompare the installed version number to the affected range: versions 40.0.2214.85 and earlier are vulnerable. Version 40.0.2214.91 and later contain the fix.Affected if If the installed version is 40.0.2214.85 or lower, the browser is affected by this out-of-bounds read vulnerability in the RenderTable caption handling.
A user is affected if Google Chrome is installed and the browser version is 40.0.2214.85 or earlier.

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 40.0.2214.91 or later to obtain the patch that fixes the RenderTable caption handling logic. No web application code changes are required as this is a browser engine vulnerability.
