3. Description:

The sudo packages contain the sudo utility which allows system
administrators to provide certain users with the permission to execute
privileged commands, which are used for system management purposes, without
having to log in as root.

Security Fix(es):

* It was found that the original fix for CVE-2017-1000367 was incomplete. A
flaw was found in the way sudo parsed tty information from the process
status file in the proc filesystem. A local user with privileges to execute
commands via sudo could use this flaw to escalate their privileges to root.
(CVE-2017-1000368)
