                   Red Hat, Inc. Security Advisory



Synopsis:          Updated usermode packages.

Advisory ID:       RHSA-2000:053-01

Issue date:        2000-08-11

---------------------------------------------------------------------



1. Topic:



Updated usermode packages are now available for Red Hat Linux 6.0, 6.1, and

6.2.



2. Relevant releases/architectures:



Red Hat Linux 6.0 - i386, alpha, sparc

Red Hat Linux 6.1 - i386, alpha, sparc

Red Hat Linux 6.2 - i386, alpha, sparc

Red Hat Linux 6.2E - i386, alpha, sparc



3. Problem description:



The usermode package allows unprivileged users logged in at the system

console to run the halt, poweroff, reboot, and shutdown commands without

needing to know the superuser's password.  While being able to halt,

poweroff, and reboot is a desirable thing, an unprivileged user can also

bring the system to single-user mode by running "shutdown now" with no

additional flags.  This update removes the "shutdown" command from the list

of commands unprivileged users can run.



4. Solution:



For each RPM for your particular architecture, run:



rpm -Fvh [filename]



where filename is the name of the RPM.



5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):



13768 - Auth dialogs show "Picture of a key" text instead of graphic

13616 - Missing icon.

12433 - /usr/sbin/userhelper not stripped

11006 - kppp either doesn't display locally or remotely

9746 - Local user can go into single mode only with shutdown now...
