Reference the CERT Advisory of October 1, 1990, CA-90:06: Problem #2 DESCRIPTION: On NeXT computers running Release 1.0 or 1.0a that also have publicly accessible printers, users can gain extra permissions via a combination of bugs. The file 'newnpd' contains the new version of the NeXT Printer Driver. To install it (from the CERT Advisory; do this as root): # /bin/mv /usr/lib/NextPrinter/npd /usr/lib/NextPrinter/npd.old # /bin/mv newnpd /usr/lib/NextPrinter/npd (In the above command, "newnpd" is the npd binary that you obtained from your NeXT support center.) # /etc/chown root /usr/lib/NextPrinter/npd # /etc/chmod 6755 /usr/lib/NextPrinter/npd
