Yes, this sshd attack vector isn’t possible. However, they haven’t decomposed the exploit and we don’t know the extent of the attack. The reporter of the issue just scratched the surface. If you are using Arch, you should run pacman right now to downgrade.
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)"

No, just update. It’s already fixed. Thats the point of rolling release.
