COMMAND
	    /dev
SYSTEMS AFFECTED
	    NetBSD, FreeBSD -current, OpenBSD
PROBLEM
	    Hubert Feyrer  found following.   In {Free,Net,Open}BSD,  any user
	    can mount a filesystem as long as he owns the mountpoint, and  has
	    appropriate access to the device  to mount from.  Almost!  For the
	    cd9660 filesystem (and  at least on  NetBSD, the filecorefs)  this
	    second  check  was  not  performed,  and  any user was able to and
	    access a CDROM whether /dev/cd0a was accessible to him or not.
SOLUTION
	    This  was  fixed  in  NetBSD  on  19980905  by Charles Hannum, the
	    problem is still present  in Free- and OpenBSD  as of the time  of
	    this writing.
	    Note that in OpenBSD only  the superuser may mount filesystems  by
	    default.  This can be changed by setting the kern.usermount sysctl
	    to 1.   The same  goes for  FreeBSD.   Also, the  problem is  only
	    relevant for FreeBSD-current,  not -stable or  the releases -  ie,
	    2.2.* does not seem vulnerable.
