No, you are mistaken. There are two issues, which is quite apparent if you do
read the bugreports.

1) People modifying /etc/pam.d files and promptly forgetting it. Breaking their
system as the new file is inserted as `/etc/pam.d/system-login.pacnew`.

2) Some change introduced into the new /etc/pam.d/system-login where auxillary
files such as ~/.pam_environment can sometimes break your system.

I have no clue how the latter works.

That is concerning, but it is simply something touching those files you are
unaware of. It's however you system and it's expected that you are aware of what
does this.

There isn't. Peopel with `.pacnew` has modified their files, wittingly or not.
