Description Doran Moppert 2020-01-07 22:36:15 UTC
During the initialization of a new content process, a pointer offset can be manipulated leading to memory corruption and a potentially exploitable crash in the parent process. 

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