6.6. Booleans for Users Executing Applications

Not allowing Linux users to execute applications (which inherit users' permissions) in their home directories and the /tmp directory, which they have write access to, helps prevent flawed or malicious applications from modifying files that users own.

Booleans are available to change this behavior, and are configured with the setsebool utility, which must be run as root. The setsebool -P command makes persistent changes. Do not use the -P option if you do not want changes to persist across reboots:

To prevent Linux users in the guest_t domain from executing applications in their home directories and /tmp:

~]# setsebool -P guest_exec_content off

To prevent Linux users in the xguest_t domain from executing applications in their home directories and /tmp:

~]# setsebool -P xguest_exec_content off

To prevent Linux users in the user_t domain from executing applications in their home directories and /tmp:

~]# setsebool -P user_exec_content off

To prevent Linux users in the staff_t domain from executing applications in their home directories and /tmp:

~]# setsebool -P staff_exec_content off

To turn the staff_exec_content boolean on and to allow Linux users in the staff_t domain to execute applications in their home directories and /tmp:

~]# setsebool -P staff_exec_content on
