When was the last time you've checked your OS vulnerability?

Everybody are talking about the sudo security vulnerability found yesterday, (CVE-2019-14287)
Because none-root users can get root privilege using sudo -u#-1 on the command line.
If sudo is enabled on you system, check your sudo version: sudo -V
The bug is fixed in sudo 1.8.28.
