backdoor in upstream xz/liblzma leading to ssh server compromise

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.

when building RPM or DEB.

Which ones? Everything I run seems to be clear.

Enterprise Linux 8	xz	Not affected

(and thus all the bug-for-bug clones)

Archlinux’s XZ was compromised as well.

No, read the link you posted:

Arch does not directly link openssh to liblzma, and thus this attack vector is not possible. You can confirm this by issuing the following command:
ldd "$(command -v sshd)"
However, out of an abundance of caution, we advise users to remove the malicious code from their system by upgrading either way.
