Actually - there's a very simple work-around, based upon the age old "chicken
and egg principle":
In order to exploit this bug, you need to have ALTER privileges on the
mysql.user table.
Just grant that privilege only to a trusted *local* account (say 'root') and
you're home free. Make sure only trusted persons know that password and don't
store it anywhere digitally (remember to remove ~/.mysql_history after
changing the password).
