Re: SECURITY PROBLEM: autofs [all versions]
anytime someone has physical access to the machine...
you already have a security problem.... ( my definition )
i am not sure that you can get physical access as root
from the options shown in /etc/auto.misc.... but if oyu
are correct....wow...wonder how many people tried it...
and only now surfaces ???
I always disable those "system defined options" anyway...
and use my own automated servers:/directories
there was lots of discussion the past couple weeks of what
needs to be in /etc/auto.master and /etc/auto.misc
and automaps from NIS and which to read first and functions
supported or not...
- newest supported feature is ldap in autofs
( sounds like time to update this thing soon -- past due )
- and nope....hpa is the maintainer/creator of autofs...
