It was xz, a software most people probably use without even knowing it as it is a library which is included in a lot of other projects. The vulnerability targeted openssh which is one of these users.
That being said: Do you also audit the dependencies of the software you're installing? I usually don't, unless a customer pays me for it. However, before I pull any dependency into one of my own projects I take a look at it's dependencies. If a library for a simple task brings tons of dependencies with it, I rather not use it.
