Fedora Update Notification
FEDORA-2021-2cb63d912a
2021-01-27 01:17:26.446133
--------------------------------------------------------------------------------

Name : sudo
Product : Fedora 33
Version : 1.9.5p2
Release : 1.fc33
URL :   https://www.sudo.ws
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.
