The true flaw here is monoculture.
'System administrator Andrew Ayer has discovered a potentially
critical bug in systemd which can bring a vulnerable Linux server to
its knees with one command. "After running this command, PID 1 is hung
in the pause system call. You can no longer start and stop daemons.
inetd-style services no longer accept connections. You cannot cleanly
reboot the system." According to the bug report, Debian, Ubuntu, and
CentOS are among the distros susceptible to various levels of resource
exhaustion. The bug, which has existed for more than two years, does
not require root access to exploit.'
