The vulnerability, identified as CVE-2017-1000367, was discovered by researchers at Qualys Security in Sudo's "get_process_ttyname()" function for Linux that could allow a user with Sudo privileges to run commands as root or elevate privileges to root.

Thank you Jerry  :)
I have checked and it is the version you specified.
When running Menu>Favorites>Install Updates there was an update for sudo.
