Description Huzaifa S. Sidhpurwala 2011-02-04 04:35:38 EST
Daniel Kozlowski reported that a JavaScript Worker could be 
used to keep a reference to an object that could be freed during 
garbage collection. Subsequent calls through this deleted 
reference could cause attacker-controlled memory to be executed 
on a victim's computer.
