Description

WebKit contains a flaw in the 'HTMLFrameElementBase::insertedIntoDocument' and 'HTMLFrameElementBase::setRemainsAliveOnRemovalFromTree' functions in WebCore/html/HTMLFrameElementBase.cpp related to handling of a "magic frame". With a specially crafted web page, a context-dependent attacker can bypass the same-origin policy restrictions.
