CVE-2016-1697
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 FrameLoader::startLoad function in WebKit/Source/core/loader/FrameLoader.cpp in Blink, as used in Google Chrome before 51.0.2704.79, does not prevent frame navigations during DocumentLoader detach operations, which allows remote attackers to bypass the Same Origin Policy via crafted JavaScript code.
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 FrameLoader::startLoad function in Blink (WebKit) fails to prevent frame navigations during DocumentLoader detach operations. This allows specially crafted JavaScript to navigate frames to different origins when such navigations should be blocked, enabling a Same Origin Policy bypass.

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 version on Windows or MacOpen Chrome, click the menu icon (three dots), select Help, then About Google Chrome. Note the version number displayed.Affected if Version displayed is 51.0.2704.63 or lower
-
Check Chromium version on Linux systemsRun 'chromium --version' or 'google-chrome --version' in a terminal to retrieve the installed browser version.Affected if Version displayed is 51.0.2704.63 or lower
-
Check installed package version on Debian/UbuntuRun 'dpkg -l | grep chromium' or 'dpkg -l | grep chrome' to list the installed browser package and its version.Affected if Package version corresponds to 51.0.2704.63 or lower
-
Check installed package version on RHEL/CentOSRun 'rpm -qa | grep -i chrome' or 'rpm -qa | grep -i chromium' to list the installed browser package and its version.Affected if Package version corresponds to 51.0.2704.63 or lower
-
Check installed package version on openSUSERun 'rpm -qa | grep -i chromium' or 'rpm -qa | grep -i chrome' to list the installed browser package and its version.Affected if Package version corresponds to 51.0.2704.63 or lower
