                   Red Hat, Inc. Security Advisory

Synopsis:          Updated usermode packages.
Advisory ID:       RHSA-2000:053-02
Issue date:        2000-08-11
Updated on:        2000-08-29
Product:           Red Hat Linux
Keywords:          usermode shutdown
Cross references:  N/A

1. Topic:

Updated usermode packages are now available for Red Hat Linux 6.0, 6.1, and 6.2. Updated SysVinit packages are also available for Red Hat Linux 6.0 and 6.1.

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 using the superuser's password. The halt, poweroff, and reboot abilities are useful, but 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.

A previous revision of this errata notice did not include the SysVinit package required to install the usermode errata on Red Hat Linux 6.0 and 6.1. Those packages are now included.

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...
16694 - There is no offcial SysVinit update for 6.0, and the new usermode package you just came out with requires one newer than is available (officially).
16664 - typos in %changelog
16586 - Cannot change shell type in userinfo for either root or user
11706 - STDOUT applications fail to work with consolehelper
17050 - Gnome logout options missing after upgrade to new usermode rpm
8299 - kppp and userhelper breaks with X11 forwarding

rpm --checksig

If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command:
rpm --checksig --nogpg
