Mozilla security researcher moz_bug_r_a4 reported that when non-priviliged XUL documents include scripts from chrome: URIs used in the browser it was possible to take advantage of the privilege level stored in the pre-compiled “fastload” file. This could allow an attacker to run arbitrary JavaScript code with chrome privileges.
