Is chmod 132 Safe?
Critical Risk
- Anyone on the system can modify or replace this file.
- Every member of the group can modify this file.
- Even the owner cannot modify this file without changing permissions first.
- Scripts need read permission to run; only compiled binaries can be executed without it.
- Unusual: a lower class has permissions the class above it lacks.
Common Use Cases
132 is uncommon in standard Linux setups. The closest widely used permission is chmod 500.
