Fedora Update Notification
FEDORA-2012-8021
2012-05-18 10:02:00
--------------------------------------------------------------------------------

Name        : sudo
Product     : Fedora 16
Version     : 1.8.3p1
Release     : 3.fc16
URL         : http://www.courtesan.com/sudo/
Summary     : Allows restricted root access for specified users
Description :
Sudo (superuser do) allows a system administrator to give certain
users (or groups of users) the ability to run some (or all) commands
as root while logging all commands and arguments. Sudo operates on a
per-command basis.  It is not a replacement for the shell.  Features
include: the ability to restrict what commands a user may run on a
per-host basis, copious logging of each command (providing a clear
audit trail of who did what), a configurable timeout of the sudo
command, and the ability to use the same configuration file (sudoers)
on many different machines.
