My mastodon feed is full of IT security specialist talking about the xz affair where someone let a backdoor in some library.
But beside showing the two side of Free/Libre software (anybody can add a backdoor, and anybody can spot it), I have no idea how it impacts the average person. Is it a common library or something used only by specific application ? Would my home-grade router protects me ?
It actually means a lot for average people. Only because you are not able to comprehend some things, does not mean you are not affected by it. But feel free to keep on using Windows XP.
