If you’re using xz version 5.6.0 or 5.6.1, please upgrade asap, especially if you’re using a rolling-release distro like Arch or its derivatives. Arch has rolled out the patched version a few hours ago.
Gentoo just reverted back to the last tar signed by another author than the one seeming responsible for the backdoor. The person has been on the project for years, so one should keep up to date and possibly revert even further back than just from 5.6.*. Gentoo just reverted to 5.4.2.

Backdoor only gets inserted when building RPM or DEB. So while updating frequently is a good idea, it won’t change anything for Arch users today.
Which ones? Everything I run seems to be clear.
