Microsoft Edge JSON.parse Information Leak

Microsoft Edge JSON.parse Information Leak
Posted Dec 2, 2016
Authored by Google Security Research, natashenka

Microsoft Edge has an information leak in JSON.parse. If this function is called with a reviver, and the reviver modifies the output object to contain a native array, the Walk function assumes that this array is a Var array, and writes pointers to it. These pointers can then be read out of the array by script.
