Google Chrome contains a use-after-free error in the 'WebContentsImpl::CreateOpenerRenderViews' function [content/browser/web_contents/web_contents_impl.cc] that is triggered as an extra RVH (RenderViewHost) may be created for a tab's opener when one is already pending. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
