Accessing XBL compilation scope via valueOf.call()
moz_bug_r_a4 discovered that the compilation scope of privileged built-in
XBL bindings was not fully protected from web content and could be accessed
by calling valueOf.call() and valueOf.apply() on a method of that binding.
giving it the privileges of the binding which would allow an attacker to
install malware such as viruses and password sniffers.
shutdown reported an alternate way to get to XBL compilation scope by
inserting an XBL method into the DOM's document.body prototype chain.
This issue also affects FC4
These issues have been resolved in FEDORA-2006-411 for FC5 and FEDORA-2006-410
