Package: kfm
Version: 1.1.2

kfmsu2 calls "xhost +local:", which is insecure.

I suggest setting the XAUTHORITY environment for root to that of the user's to 
securely give root access to the display:

Remove "xhost +local:" and change su:

su - root -c "XAUTHORITY=$HOME/.Xauthority; DISPLAY=$DISPLAY; \
    export XAUTHORITY DISPLAY; $kfm -sw >/dev/null"

I am using both Debian Slink and Redhat 6.0 with updates.
