I don't think fedora is vulnerable to this, the xauth files are stored under protected /var/run/$user dirs by default, per /etc/lightdm/lightdm.conf option:
For example, on my box:
$ ls -l /var/run/lightdm
drwx------. 2 lightdm lightdm 60 Sep 10 09:58 lightdm
drwx------. 2 rdieter1 root 60 Sep 12 08:13 rdieter1
But, non-default configurations could be. I'll issue updates anyway.
