It and your proposed solution leaves the system in an unpatched state where there are known exploits. It doesn't fix it, it makes it worse.

Here is a list of 72 known exploits your "fix" re-introduces.
https://www.ubuntu.com/usn/
You'll notice that the exploit you're concerned about is still on that list. So your solution doesn't fix the problem it just adds 71 more in addition to the heavy work of re-establishing the system configuration after an FFR. Which in the case of some computers requires manually editing config files just to get the internet functional, raid drivers running and don't get me started on 3D graphics.

I am not sure I follow you. What are you talking about here?

I have said in my article that if the solution is fixed, only then download he latest release. I was also implying but forgot to say that the latest "stable" release should be downloaded, if that is a more accurate explanation, i will edit it in the article.

Other than that how is it actually more risky to update than to leave the current flawed version on the PC?

Just for the record , I am not using Ubuntu. I was referring to Debian mostly.
