7. The superuser wants to give Alice a permission to view all the files in the system using the more command. He does the following: s cp /bin/more/tmp/mymore $ sudo chown root /tmp/mymore sudo chmod 4700/tmp/mymore Basically, the above commands turns/tmp/mymore into a Set-UID program. Right now, because the permission is set to 4700, other users cannot execute the program. The superuser uses another command (not shown) to grant the execution permission only to Alice. We are not assuming that Alice is completely trusted. It is OK if Alice can only read other people's files, but it is not OK if Alice can gain any privilege beyond that, such as writing to other people's files. Please read the manual of the more program and find out what Alice can do to gain more privilege. (10pt)
