If a security boundary is crossed then yup. E.g. you can monkey with
the programs log files/config/etc. (cover up attacks/etc.) or possibly
crash the program/cause a dos (forcing it to append/process huge
files, etc.). Alternatively you can use the directory to stash files
(and typically the admin only expects /tmp/, /var/tmp/) and so on.

Basically it's a lot like /tmp/ file creation issues. They are low
level, rarely fatal, but they are security issues that need to be
addressed. I'll do separate emails for them to make tracking easier.
