Reproducable in devel on 13th Jan 2006.


Comment 4 Nils Philippsen 2006-03-07 12:22:12 UTC
This will have to wait until after FC5 is out as s-c-users uses libuser which
uses /etc/libuser.conf (and not /etc/login.defs) which doesn't provide means to
set the home directory mode.

Comment 6 Miloslav Trmač 2006-03-07 14:02:45 UTC
libuser currently hardcodes mode 0700.

I personally consider the default permissions of 0750 on home directories
created by adduser a security issue (if not in the application, at minimum in
the default configuration); useradd did use 0700 in the past (using an RH
patch to the default configuration, IIRC), why was it changed?

#160644 doesn't really explain anything, neither does the lack of an upstream
answer in the thread at #160644c2;  security should trump upstream defaults
IMHO.  I must have overlooked some important reason for the status quo...

As I recall, firstboot is now using luseradd to add users only because luseradd
uses mode 0700.

Comment 7 Need Real Name 2006-03-07 14:09:10 UTC
off-topic, but you'd probably be horrified to see what debian does:
world readable /home/username AND /root/. ugh.

Comment 8 Peter Vrabec 2006-03-07 15:38:44 UTC
Finally, I changed shadow-utils to use mode 0700 by default.
