COMMAND

    /dev/hd[abcd]

SYSTEMS AFFECTED

    RedHat 6.0

PROBLEM

    Salvatore Sanfilippo found following.  Another permission  problem
    in  RedHat  6.0  like  the  previous  one  is  the  cdrom   device
    /dev/hd[abcd].   It's  world   readable  (think  about   backups).
    Anyway  if   you  are   RedHat   6.0   user  check   your   /dev/*
    permissions/owners.

SOLUTION

    In fstab change permissions.
