Comment 3 Stefan Cornelius 2017-05-11 08:41:35 UTC
The division by zero (which is hardly a security issue already) is caused by passing the zero/0 as a command line parameter. I can't think of a reasonable scenario where this would be any different from shooting yourself in the foot. Thus, I'm not convinced of the security impact.
