On this, Free is better too, as the corrections are patched and distributed faster than on closed source. I know the failure has passed upon on 10 years, but now almost all distros are patching those system
It’s a good thing to stumble upon that kind of article but as a rather newbie it’s always a disappointment to not find in the article any info on how you check the sudo version or update 
I know it’s basic info and most of the audience here don’t need that. I kind of guess what I have to do but a 3 lines reminder wouldn’t hurt.
I found the infos elsewhere and the thing now is when I try to update terminal is telling me sudo is already the latest version (1.9.1-1ubuntu1.1) but in the article the recommended version is sudo-1.9.5p2 
(Pop OS 20.10)
I’m running a LinuxLite distro atm on a vm, and it seems that it’s patched. Did you run the latest updates for your distro? It should be fixed by now.
It’s unfortunate that it took about 10 years to get fixed, but better late then never i suppose.
I think it is telling you that because it is the latest version in your versions repository. I would hope that you will see an update very soon.
Oh. I saw the check ( sudoedit -s /) but hadn’t realised people used distributions without first learning how to update the system.
Anyway, having updated recently I passed that test over a week ago now anyway. If I hadn’t, and didn’t know how to, then I’d ask in the forum for my distribution…
You raise a good point about mentioning how to check for current version. I will keep that in mind in future articles. Thank you for the feedback.
Well that was a nice snarky reply 
First thing I tried was sudo update but as nothing was updating I wondered how to check sudo version, which bring us to my reply here.
I could have gone to Pop os forum but I saw the article here and this forum is generally welcoming 
You’re welcome, I know it’s not always easy to be complete or figure out what is not evident for others 
You thought my reply was snarky?
No not you, not at all 
look at who I was replying in the upper right
That was intended to ben2talk. I tried to quote each time but apparently discourse removed automatically the quotes

Hey buddy the back slash is \ , the forward slash is /. 
Others:
To check the sudo version you can do a: sudo -V or sudo --version for RedHat and Ubuntu. You can also do a: man sudo on either platform and it will tell you that as well.

@ITGuyEric good to know you’re human too and I appreciated the heads up back when you posted.
