Description

Mozilla security researcher moz_bug_r_a4 reported that it was possible to use the Script object to modify XPCNativeWrappers in such a way that subsequent access by the browser chrome--such as by right-clicking to open a context menu--can cause attacker-supplied javascript to run with the same privileges as the user. This is similar to MFSA 2007-25 fixed in Firefox 2.0.0.5
