Ensure permissions on /etc/issue are configured

How it is checked

Audit method: Shell command

alt0() { command -v stat >/dev/null 2>&1 || { echo "step1: stat not installed"; return 1; }; o=$(bash -c 'stat /etc/issue' 2>&1); printf '%s\n' "$o" | tr -s ' \t' '  ' | sed 's/^ //;s/ $//' | grep -Fxq -- 'Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root)' || { echo step1: missing 'Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root)'; return 1; }; }; if alt0; then echo compliant; fi

Expected output

compliant

How it is fixed
