SV-72849r1_rule The default global umask setting must be changed for system processes.

Vulnerability discussion

The default global umask setting must be set to '022' for system processes. The setting '022' ensures that system process created files and directories will only be readable by other users and processes, not writable. This mitigates the risk that unauthorized users might be able to write to files and directories created by system processes. A more restrictive setting could potentially break the normal functionality of the system.

Check content

To view the umask setting, run the following command: umask If the setting is not '022', this is a finding.

Fix text

To set the umask setting for applications, run the following command: sudo sh -c 'echo 'umask 022' > /etc/launchd.conf'

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
