Security researcher Mariusz Mlynski, via TippingPoint's Pwn2Own contest, reported that it is possible for untrusted web content to load a chrome-privileged page by getting JavaScript-implemented WebIDL to call window.open(). A second bug allowed the bypassing of the popup-blocker. Combined these two bugs allow an attacker to load a JavaScript URL that is executed with the full privileges of the browser, which allows arbitrary code execution. In general this flaw cannot be exploited through email in the Thunderbird and Seamonkey products because scripting is disabled, but is potentially a risk in browser or browser-like contexts.
