Re: [Xen-users] XCP: Insecure Distro ?
Well, you are right from the multi-user point of view regarding the
passwd file, but XCP is designed as appliance, xe utility or something
speaking xapi is a way of interfacing it, no user other than root should
access dom0.
Updates - question of stability, i hope you do not want to risk reload
of all your VM`s due to libc changes or something like that :). You
need to update what? Xen hypervisor? Openvswitch, xapi toolstack?
Everything should be locked down on lower levels (network access to
dom0, physical access to appliances).
Try to change the point of view and stop looking at it as a standard
multiuser linux enviroment.

Hello mailing list!
I have been working with XCP a little bit, and I have the impression
that this distro is insecure. First, it does not look like update
repositories are enabled inside /etc/yum.repos.d, although I'm from an
apt background so I may be misinterpreting that. Where will my
security updates come from?
Next, it appears that the root password hash is directly stored inside
/etc/passwd, which is set to world-readable! There does not appear to
be an /etc/shadow file at all.
Unfortunately I am dropping the distro entirely due to security
concerns, I hope that these problems can be fixed.
