some sys tables available to all users?

Hello,

I created a new user which I intend to only have SELECT privs on a view of a table on another schema. I then just granted this user create session and select to the view. However, when I do a SELECT owner, table_name
  FROM all_tables;

I see more than I expected to. As this supposedly limited user, I can do selects on sys.system_privilege_map, sys.audit_actions, etc. I also use TOAD and notice this user can also see some of the TOAD user's tables such as toad_plan_table.

Is this normal? Is this safe?

TIA,
