Description Doran Moppert 2019-05-22 01:42:54 UTC

A vulnerability exists in the Windows sandbox where an uninitialized value in memory can be leaked to a renderer from a broker when making a call to access an otherwise unavailable file. This results in the potential leaking of information stored at that memory location. 

*Note: this issue only occurs on Windows. Other operating systems are unaffected.*
