Check Text (C-271811r1092145_chk)
Verify that OL 9 configures the "/etc/passwd-" file to have a mode of "0644" or less permissive with the following command:
$ stat -c "%a %n" /etc/passwd-
644 /etc/passwd-
If a value of "0644" or less permissive is not returned, this is a finding.
Fix Text (F-75768r1092144_fix)
Change the mode of the file "/etc/passwd-" to "0644" by running the following command:
$ sudo chmod 0644 /etc/passwd-
