10.5: Share any files between users on the same Mac
Also, this hint doesn't give other users "permission to execute arbitrary code in your user space." Any code they might execute is run as themselves, not as you.
Perhaps you have this confused with the setuid and setgid bits, which do allow a user to run code as if they were someone else.
10.5: Share any files between users on the same Mac
what I meant was they can place any script they like in your user directory and execute it. what happens if someone wrote a script like
from a script located in your pictures folder. it probably wouldn't work, but if it did it would delete your home directory. again, what advantage do you get out of granting execute privileges that makes opening the door to this kind of thing acceptable?
10.5: Share any files between users on the same Mac
This hint describes using the ACLs to set permissions on a folder inside /Users/Shared, not a user's home folder (/Users/username). A bash script such as the one you mention would only affect the Shared folder, not anyone's home folder. |
