Well, you have to look carefully, because not all uses of
`make-temp-name' are insecure.  If you create a new temporary
subdirectory that is not world-writable, and then create files inside of
there, you're fine (as, for example, gnus-uu.el appears to do). 
However, it is still probably better to use `make-temp-file' regardless,
but Gnus probably has to consider portability between Emacsen.
