Blink, as used in Google Chrome before 43.0.2357.130, does not properly restrict the creation context during creation of a DOM wrapper, which allows remote attackers to bypass the Same Origin Policy via crafted JavaScript code that uses a Blink public API, related to WebArrayBufferConverter.cpp, WebBlob.cpp, WebDOMError.cpp, and WebDOMFileSystem.cpp.
