From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

That attack surface is not vanishing. It's would be relocating the same attack surface to something that might have an xz library in memory.

The attack surface is there either way, this is just functionality repackaged that existed already before (systemd-run, which is calling into PID1)
all compression libraries (actually most libraries at this point) are dlopened on demand (which was planned even before the attack, which is speculated that the attack was accelerated in timeline because he was on a timer before the change was released)

As Microsoft and Poettering intended.
