Re: /dev/fb* permissions, local DoS
this is some strange
hour:/home/kr0n# cat /dev/urandom > /dev/fb0
bash: /dev/fb0: No such device
hour:/home/kr0n# ls -ls /dev/fb0
0 crw--w--w- 1 root tty 29, 0 Jul 5 14:44 /dev/fb0

So 0620 might be better, with /dev/fb in group video or a dedicated group.
that seems more reasonable.
This is on a SuSE 6.4 system BTW:
crw-rw---- 1 root video 29, 0 Mar 11 2000 /dev/fb0
this is broken IMO, it allows all members of group video to grab a
copy of the current framebuffer contents. 620 is safer.
