Using library routines
A trusted command must never
use an untrusted library routine.
This restriction means that a trusted command
must never use a library routine that has an
untrusted call anywhere in its calling sequence,
nor a library routine
that causes an untrusted command to be executed.
The information derived
from the untrusted command might
influence the behavior of the trusted command,
or the command might give away
extraordinary access to the untrusted command;
neither action is acceptable.
