Description

WebKit contains a flaw in WebCore/bindings/v8/custom/V8DOMWindowCustom.cpp within the JavaScript bindings. The issue is related to the window.open logic and allows a popped up window to confuse a top-level page into believing that the new window is a direct child. With a specially crafted web page, a context-dependent attacker may bypass the same origin policy.
