Functionality added or changed:
* The time zone tables available at
http://dev.mysql.com/downloads/timezones.html have been
updated. These tables can be used on systems such as Windows or
HP-UX that do not include zoneinfo files. (Bug#40230)
Bugs fixed:
* Security Fix: During evaluation of arguments to extreme-value
functions (such as LEAST() and GREATEST()), type errors did not
propagate properly, causing the server to crash. (Bug#55826,
CVE-2010-3833)
* Security Fix: The server could crash after materializing a derived
table that required a temporary table for grouping. (Bug#55568,
CVE-2010-3834)
* Security Fix: A user-variable assignment expression that is
evaluated in a logical expression context can be precalculated in a
temporary table for GROUP BY. However, when the expression value is
used after creation of the temporary table, it was re-evaluated, not
read from the table and a server crash resulted. (Bug#55564,
CVE-2010-3835)
* Security Fix: Joins involving a table with a unique SET column could
cause a server crash. (Bug#54575, CVE-2010-3677)
* Security Fix: Pre-evaluation of LIKE predicates during view
preparation could cause a server crash. (Bug#54568, CVE-2010-3836)
* Security Fix: GROUP_CONCAT() and WITH ROLLUP together could cause a
server crash. (Bug#54476, CVE-2010-3837)
* Security Fix: Queries could cause a server crash if the GREATEST()
or LEAST() function had a mixed list of numeric and LONGBLOB
arguments, and the result of such a function was processed using an
intermediate temporary table. (Bug#54461, CVE-2010-3838)
* Security Fix: Using EXPLAIN with queries of the form SELECT
... UNION ... ORDER BY (SELECT ... WHERE ...) could cause a server
crash. (Bug#52711, CVE-2010-3682)
* InnoDB Storage Engine: Creating or dropping a table with 1023
transactions active caused an assertion failure. (Bug#49238)
* The make_binary_distribution target to make could fail on some
platforms because the lines generated were too long for the
shell. (Bug#54590)
* A client could supply data in chunks to a prepared statement
parameter other than of type TEXT or BLOB using the
mysql_stmt_send_long_data() C API function (or
COM_STMT_SEND_LONG_DATA command). This led to a crash because other
data types are not valid for long data. (Bug#54041)
* Builds of the embedded mysqld would fail due to a missing element of
the struct NET. (Bug#53908, Bug#53912)
* The definition of the MY_INIT macro in my_sys.h included an
extraneous semicolon, which could cause compilation
failure. (Bug#53906)
* If the remote server for a FEDERATED table could not be accessed,
queries for the INFORMATION_SCHEMA.TABLES table failed. (Bug#35333)
* mysqld could fail during execution when using SSL. (Bug#34236)
* Threads that were calculating the estimated number of records for a
range scan did not respond to the KILL statement. That is, if a
range join type is possible (even if not selected by the optimizer
as a join type of choice and thus not shown by EXPLAIN), the query
in the statistics state (shown by the SHOW PROCESSLIST) did not
respond to the KILL statement. (Bug#25421)
