Wouldn't that allow them to run anything as root? Because if s/he
can run an editor as root, that editor can fork off new processes.
Wouldn't it be better to change the mode of /etc/hosts to allow
group editing, create a 'hosts' group, 'chgrp hosts /etc/hosts', and
then add the allowed user(s) to the hosts group?
You still have to worry about concurrent editing, whatever route
you take.

You could always do
chmod a+rw /etc/hosts.
Not terribly safe if you do not trust all of your users.

This appears to have almost exactly the same effect as chmod 765
/etc/hosts.
Why have you chosen permissions of 765, though?
This is equivalent to "u=rwx,g=rw,o=rx", which sets executable permission
for the owner and everyone not in the file's group permissions. I think
other people's suggestions of chmod 664 ("ug=rw,o=r") are better,
putting permitted editors of the hosts file into an editors group,
and ensuring the file has that same group membership.

Yes you are right. My thought was put the hosts file into a directory
with ugo=rwx permissions to reduce the number of sudoers. The actual
permissions were demonstrative, ie, not well thought out.
