We want to stop systemd from being added to docker images, because of rpm requiring systemctl.

i shut when i say - not when you say


google as example for CVE-2014-0038 and as i already explained
you: a attacker has no shell, you have two ways to force a existing
local exploit by a web-application:

A: try to get a complete script on the machine and execute it
B: find a very likely present binary and bring it to do the
   rest of the attack for you with arbitary input

if you find B it's much easier because pass unsanitized input
to a web-script calling system() with it is one thing,
find a way to create a local file with whatever input you like
and execute it finally is a complete different world and needs
much more than one security problem in the web-application

in case it don't sanitize user input, calling a already running
privileged  process and feed it with arbitary input damend

do you really pretend that never happened in the past?
and no i do not get paied to seek archives for you!
