CVE-2015-1235
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 ContainerNode::parserRemoveChild function in core/dom/ContainerNode.cpp in the HTML parser in Blink, as used in Google Chrome before 42.0.2311.90, allows remote attackers to bypass the Same Origin Policy via a crafted HTML document with an IFRAME element.
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 Same Origin Policy bypass vulnerability exists in the ContainerNode::parserRemoveChild function in Blink's HTML parser. The flaw allows a remote attacker to craft a malicious HTML document containing an IFRAME that can bypass SOP restrictions, potentially allowing unauthorized cross-origin access to sensitive content.

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 versionOpen Chrome, click the menu icon (three dots), select Help > About Google Chrome. The version number is displayed on that page.Affected if Version is 42.0.2311.60 or lower
-
Check Chromium browser versionFor Chromium-based browsers (not Chrome), access the browser's About page via the menu or navigate to chrome://version in the address bar to view the version information.Affected if Chromium version corresponds to the 42.0.2311.60 or earlier release and includes the vulnerable Blink engine
-
Verify the Blink rendering engine versionIn Chrome or Chromium-based browsers, open the address bar and navigate to chrome://version. Look for the 'Blink' revision number shown in the UI and compare it to the revision range that contained the patch for this vulnerability.Affected if The Blink revision matches versions prior to the fix for the ContainerNode::parserRemoveChild SOP bypass
A user is affected if they are running Google Chrome 42.0.2311.60 or earlier, or any Chromium-based browser using a Blink engine version from that timeframe, and using the browser to render untrusted HTML content with IFRAME elements.
Generated from the published advisory. Verify against your own configuration.
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 42.0.2311.90 or later. For embedded Blink instances, apply the corresponding Chromium patch addressing the ContainerNode::parserRemoveChild function.
