Details

Check Text ( C-42497r1_chk )
Check the modes of local initialization files.

Procedure:
# for HOMEDIR in $(cut -d: -f6 /etc/passwd); do find ${HOMEDIR} ! -fstype nfs -type f -name '\.*' \( -perm -0002 -o -perm -0020 \); done

If local initialization files are more permissive than 0740 or the .dt directory is more permissive than 0755 or the .dtprofile file is more permissive than 0755, this is a finding.
Fix Text (F-38550r1_fix)
Ensure user startup files have permissions of 0740 or more restrictive. Examine each user’s home directory and verify all file names beginning with “.” have access permissions of 0740 or more restrictive. If they do not, use the chmod command to correct the vulnerability.

Procedure:
# chmod 0740 .filename

Note: The period is part of the file name and is required.
OR
# for HOMEDIR in $(cut -d: -f6 /etc/passwd); do FILES=$(find ${HOMEDIR} ! -fstype nfs -type f -name '\.*' \( -perm -0002 -o -perm -0020 \) ); for INIFILE in ${FILES}; do chmod 600 ${INIFILE}; done; done
