VULNERABILITY DETAILS

My Mac (OS X 10.9.5) with Chrome 50 crashed on a page reload. On restart I was requested if I wanted to submit the bug to Apple. The exception mentioned "BSD process name corresponding to current thread: Google Chrome".

I would not have been extra concerned except that I am now missing iTerm2.app.

I verified the disk and there are not any problems. 

Maybe it is a long shot... but it is a strange coincidence that the iTerm2.app is missing after the crash and the disk does not have any corruption.


VERSION
Chrome Version: 50 stable
Operating System: OS X 10.9.5 updated

REPRODUCTION CASE
I cannot recreate the problem
