RedHat 6.x RHSA-2000:053-02 critical: shutdown command restriction
Summary
Summary
The usermode package allows unprivileged users logged in at the systemconsole to run the halt, poweroff, reboot, and shutdown commands withoutusing the superuser's password. The halt, poweroff, and reboot abilitiesare useful, but an unprivileged user can also bring the system tosingle-user mode by running "shutdown now" with no additional flags. Thisupdate removes the "shutdown" command from the list of commandsunprivileged users can run.A previous revision of this errata notice did not include the SysVinitpackage required to install the usermode errata on Red Hat Linux 6.0 and6.1. Those packages are now included.
Solution
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
