This is almost certainly caused by a bad configuration on your
workstation. The proper protections for thes files are listed below.
Please note that they are *not* world-readable. /bin/ps should be a
set-gid kmem program.
boom# ls -lg /dev/{kmem,drum,mem}
crw-r----- 1 root kmem 7, 0 Aug 27 19:38 /dev/drum
crw-r----- 1 root kmem 3, 1 Aug 27 19:38 /dev/kmem
crw-r----- 1 root kmem 3, 0 Aug 27 19:38 /dev/mem
boom# ls -lg /bin/ps
-rwx--s--x 1 root kmem 159744 Mar 19 09:47 /bin/ps
