Mozilla WebIDL chrome-privileged JavaScript execution via window.open
CVE-2014-1510 is a privilege-escalation vulnerability in the Web IDL implementation in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25. According to the provided description, a remote attacker can use an IDL fragment to trigger a window.open call and cause arbitrary JavaScript to execute with chrome privileges. In Mozilla terminology, chrome privileges correspond to highly privileged browser-internal execution context, making this effectively a sandbox/privilege boundary bypass from web content into privileged browser code.
