Recently Red Hat fixed an important vulnerability in sudo: https://access.redhat.com/security/cve/cve-2017-1000367
From the description:
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.
I wonder what the regular user should do to “use this flaw”? Is it a simple operation?
