  - An error in propagating the type errors, which allows remote attackers
  to cause a denial of service via crafted arguments to extreme-value functions
  such as 'LEAST' or 'GREATEST'.

  - An unspecified error in vectors related to materializing a derived table
  that required a temporary table for grouping and user variable
  assignments.

  - An error in handling prepared statements that uses GROUP_CONCAT with the
  WITH ROLLUP modifier.

  - An error in handling a query that uses the GREATEST or LEAST function
  with a mixed list of numeric and LONGBLOB arguments.");
