Description Huzaifa S. Sidhpurwala 2011-06-20 06:41:00 UTC

Security researcher Martin Barbella reported that under certain conditions,
viewing a XUL document while JavaScript caused deleted memory to be accessed.
This flaw could potentially be used by an attacker to crash a victim's 
browser and run arbitrary code on their computer.
