This is exploit code for CVE-2019-5736 (and it works for both runc and LXC). The simplest way to use it is to copy the exploit code into an existing container, and run make.sh. However, you could just as easily create a bad image and run that. This affects runc versions prior to 1.0-rc6 (Docket versions less than 18.09.2).
