Security Notes

• The linked OpenSSL library for the MySQL Commercial Server has been updated to version 1.0.2r. Issues fixed in the new OpenSSL version are described at http://www.openssl.org/news/vulnerabilities.html.

  This change does not affect the Oracle-produced MySQL Community build of MySQL Server, which uses the yaSSL library instead. (Bug #28988091)

Bugs Fixed

• Important Note: The libevent library included with the MySQL Server was upgraded to version 2.1.8. (Bug #28207237, Bug #29041505, Bug #29055011)

• InnoDB: The INDEX_LENGTH value in INFORMATION_SCHEMA.TABLES was not updated when adding an index. (Bug #19811005)

• Partitioning: An AUTO_INCREMENT key added to a partitioned table by an ALTER TABLE statement using ALGORITHM=INPLACE restarted on each partition. (Bug #92241, Bug #28573894)

• Replication: If an applier thread was stopped while it was in the process of opening a table, no error was set, which could result in a segmentation fault or assertion depending on the build type. Error handling is now correctly activated in this situation. (Bug #28864557)

• Replication: If a storage engine has the capability to log in STATEMENT format but not in ROW format, when binlog_format is set to STATEMENT, an unsafe SQL statement should be logged and a warning message should be written to the error log. However, such statements were instead not executed and an error message was written to the error log, which is the correct behavior when binlog_format is set to MIXED or ROW. The issue has now been corrected so that unsafe statements are logged with a warning as expected when binlog_format is set to STATEMENT. (Bug #28429993, Bug #73936)

• Microsoft Windows: Validity testing for the named_pipe_full_access_group system variable did not account for NULL values. (Bug #29256690)

• MySQL 5.6 did not build with maintainer mode enabled with GCC 7. (Bug #29048768)

• A damaged mysql.user table could cause a server exit. (Bug #28986737)

• mysqladmin shutdown did not wait for mysqld to shut down. (Bug #28466137, Bug #91803)

  References: This issue is a regression of: Bug #25364806.

• Some status variable values could temporarily increase before returning to their original value. (Bug #27839644, Bug #90351)

• The binary file for the udf_example user-defined function was omitted from binary distributions. (Bug #26115002, Bug #29178542)

• Compiling the InnoDB memcached plugin did not work on some platforms where MySQL was configured using -DWITH_LIBEVENT=system, for libevent version 2.0 or higher. (Bug #80073, Bug #22573379, Bug #23567441)
