As Ruslan Ermilov wrote: > All you need to do is to change the ownership on catpages holding > directories back to ``man'', and install man(1) setuid ``man''. ...until the next "make installworld". That's why i'm asking for a knob in /etc/make.conf. setuidperl can get its suid bit `sticky' by the same way. > But because it was proven to be insecure in many ways (the most > important leak is a customized environment), I don't like the idea > of even putting the required knobs back to src/. But all that can be compromised is user "man", isn't it? I don't care much about this. Get me right, it's OK by me to put a big warning above that knob into /etc/defaults/make.conf. But for sites less concerned about security (like my home computer), compromising the "man" account by the only other user on my machine (that's my wife :) isn't anything i would care much about. Even though the machine is pretty fast, i prefer the cached catpages for efficiency. (setuid root binaries are a totally different matter, since they might always serve as a target by a potential intruder. But i don't think such an intruder would gain much by breaking a setuid man man(1), and then replace all my catpages. ;-) > > I hope man(1) > > is smart enough to handle that situation, and would reformat > > the more recent man source instead of displaying the stale > > catpage then. > Yes, man(1) handles this.
