Description

This module attempts to gain root privileges by blindly injecting into
the session user's running shell processes and executing commands by
calling `system()`, in the hope that the process has valid cached sudo
tokens with root privileges.

The system must have gdb installed and permit ptrace.

This module has been tested successfully on:

Debian 9.8 (x64); and
CentOS 7.4.1708 (x64).
