DESCRIPTION:
Some vulnerabilities have been reported in MariaDB, which can be
exploited by malicious users to cause a DoS (Denial of Service).

1) A NULL pointer dereference error within the
"test_if_skip_sort_order()" function (sql_select.cc) when executing
subqueries can be exploited to crash the service via a specially
crafted query.

2) An error exists within the "select_describe()" function
(sql/sql_select.cc) when handling certain subqueries, which frees
certain currently used tables and can be exploited to cause a crash
via a specially crafted query.

3) An error when handling the query cache when running parallel
queries can be exploited to cause a crash via specially crafted
queries run in parallel.

The vulnerabilities are reported in version 5.5.25. Other versions
may also be affected.

SOLUTION:
Fixed in development version 5.5.27.

PROVIDED AND/OR DISCOVERED BY:
1, 2) Reported by the vendor.
3) jbergstroem in a bug report
