The upstream release tarballs for xz version 5.6.0 and 5.6.1 contain malicious code which adds a backdoor.

ArchLinux and most rolling release distro are affected.

Debian Testing/Sid/Experimental are affected, Debian Stable ISN'T AFFECTED.

Short summary by the ArchLinux team: https://archlinux.org/news/the-xz-package-has-been-backdoored/

Your distro should have a blog post/message to tell you what to do, either update (if they provide an updated version) or downgrade to a known-good version.
