Description Huzaifa S. Sidhpurwala 2011-02-04 09:31:42 UTC 
Security researcher Christian Holler reported that the JavaScript 
engine's internal mapping of string values contained an error in 
cases where the number of values being stored was above 64K. 
In such cases an offset pointer was manually moved forwards and 
backwards to access the larger address space. 

If an exception was thrown between the time that the offset pointer 
was moved forward and the time it was reset, then the exception 
object would be read from an invalid memory address, potentially 
executing attacker-controlled memory.
