Ensure access to /etc/shells is configured

How it is checked

Audit method: Shell command

alt0() { s=$(stat -Lc '%a %u %g' /etc/shells 2>&1) || { echo "step1: $s"; return 1; }; set -- $s; m=$((8#$1)); [ $((m & ~0644)) -eq 0 ] && [ "$2" = 0 ] && [ "$3" = 0 ] || { echo "step1: /etc/shells is mode $1 uid $2 gid $3, want 644 or stricter, uid 0, gid 0"; return 1; }; }; if alt0; then echo compliant; fi

Expected output

compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Run the following commands to remove excess permissions, set owner, and set group on /etc/shells: # chmod u-x,go-wx /etc/shells # chown root:root /etc/shells
