Once again, Linux proving that is not better than Windows in terms of security and that its attack surface is just as nasty if not worse.

>tl;dr
New Ubuntu version that has made the change to systemd a while back has a security flaw in login screen that can let anyone access your files, olders versions that use upstart are obviously not affected.

>Canonical has already pushed out a update that temporarily disables Ubuntu guest session logins (so if you noticed it was missing, that’s why).

Enjoy your shitty wannabe Windows registry linux faggots. Real Unix systems like MacOS or *BSD don't have this problem.

What's next? a keylogger hidden in pulseaudio?

Fuck off. If you want to use GNOME, you must have it. If you install a distro that isn't Gentoo, Slack, or Devuan you'll get it by default and most people won't bother changing it.

Wrong.
AppArmor is considered only *after* passing the standard Unix file permissions, so no one has access to your files unless you open them up to the world yourself.
Also, you have to physically access the machine to log in as guest. If an attacker has physical access, you are beyond fucked anyway.

I'd just like to interject for a moment. What you're referring to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called "Linux", and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.

There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called "Linux" distributions are really distributions of GNU/Linux.

Sure it's optional if you're fine with a completely mute experience, it's only optional in the sense that you can run firefox without it. But since they removed ALSA compatability you get no sound at all if you don't have pulseaudio installed.
