Description Doran Moppert 2019-05-22 01:46:54 UTC
A race condition is present in the crash generation server used to generate data for the crash reporter. This issue can lead to a use-after-free in the main process, resulting in a potentially exploitable crash and a sandbox escape. 

*Note: this vulnerability only affects Windows. Other operating systems are unaffected.*
