Fedora 32: 2020-03-16 Critical: sudo Buffer Overflow Fix

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.
