BUG#31611 (Security risk with BINLOG statement):

Browse Source 
Adding check that the user executing a BINLOG statement has SUPER
privileges and aborting execution of the statement with an error
otherwise.


mysql-test/r/mysqlbinlog.result:
  Result change.
mysql-test/t/mysqlbinlog.test:
  Adding test that generates a BINLOG command for inserting data into a
  table and feed the BINLOG statement into the database as an untrusted
  user. Also checking that insertion into the table fails for that user
  and that the table only contain a single line: the original one inserted.
sql/sql_binlog.cc:
  Adding a check that the executor of the BINLOG command has
  SUPER privileges and give an error and abort execution if not.
