KDE supports creating "thumbnail" pictures to represent different types of
files on the desktop and could also be vulnerable to "list a directory and
have some code executed" type bugs.
The problem with KDE is that everything seems to be run from one process that
just forks off copies of itself and mmap's executables (thus avoiding
automatic domain transitions).
I think that this is relevant to people who are writing SE Linux policy. It
does not affect Linux, yet, AFAIK... But sometimes it's best to lock down
things that look dangerous rather than waiting for proof that they are
dangerous (you never get absolute proof that anything is safe).
