Changes in MySQL 5.5.52 (2016-09-06)

Bugs Fixed
----------
Replication: mysqlbinlog --read-from-remote-server log1 log2 was opening a new \ 
connection for log2 without freeing the connection used for log1. Thanks to \ 
Laurynas Biveinis for the contribution. (Bug 81675, Bug 23540182)

For mysqld_safe, the argument to --malloc-lib now must be one of the directories \ 
/usr/lib, /usr/lib64, /usr/lib/i386-linux-gnu, or /usr/lib/x86_64-linux-gnu. In \ 
addition, the --mysqld and --mysqld-version options can be used only on the \ 
command line and not in an option file. (Bug 24464380)

It was possible to write log files ending with .ini or .cnf that later could be \ 
parsed as option files. The general query log and slow query log can no longer \ 
be written to a file ending with .ini or .cnf. (Bug 24388753)

Privilege escalation was possible by exploiting the way REPAIR TABLE used \ 
temporary files. (Bug 24388746)

Certain internal character-handling functions could fail to handle a too-large \ 
character and cause a server exit. (Bug 23296299)

A blank server name in CREATE SERVER statements produced a server exit rather \ 
than an error. (Bug 23295288)

The optimizer failed to check a function return value for an area calculation, \ 
leading to a server exit. (Bug 23280059)

A prepared statement that used a parameter in the select list of a derived table \ 
that was part of a join could cause a server exit. (Bug 22392374, Bug 24380263)

MEDIUMINT columns used in operations with long integer values could result in \ 
buffer overflow. (Bug 19984392)

EINTR handling in the client library has been fixed so that interrupted read and \ 
write calls are retried. Previously, EINTR was ignored. (Bug 82019, Bug \ 
23703570)

Bugs Fixed

Replication: When using statement-based or mixed binary logging format with \ 
--read-only=ON, it was not possible to modify temporary tables.

MySQL Server upgrades performed using RPM packages failed when upgrading from \ 
MySQL 5.1 Community to MySQL 5.5 Community or MySQL 5.1 Commercial to MySQL 5.5 \ 
Commercial.

A buffer overflow in the regex library was fixed.

Certain arguments to NAME_CONST() could cause a server exit.

Installing MySQL from a yum or zypper repository resulted in /var/log/mysqld.log \ 
being created with incorrect user and group permissions.

If a stored function updated a view for which the view table had a trigger \ 
defined that updated another table, it could fail and report an error that an \ 
existing table did not exist.

If an INSTALL PLUGIN statement contained invalid UTF-8 characters in the shared \ 
library name, it caused the server to hang (or to raise an assertion in debug \ 
builds).

For multibyte character sets, LOAD DATA could fail to allocate space correctly \ 
and ignore input rows as a result.

Changes 5.5.0:

Functionality Added or Changed

The version of the tcmalloc library included in MySQL distributions was very \ 
old. It has been removed and is no longer included with MySQL.

Bugs Fixed

INSERT with ON DUPLICATE KEY UPDATE and REPLACE on a table with a foreign key \ 
constraint defined failed with an incorrect “duplicate entry” error \ 
rather than a foreign key constraint violation error.

Setting sort_buffer_size to a very large value could cause some operations to \ 
fail with an out-of-memory error.

Several potential buffer overflow issues were corrected.

If the CA certificate as given to the --ssl-ca option had an invalid path, yaSSL \ 
returned an error message different from OpenSSL. Now both return SSL connection \ 
error: SSL_CTX_set_default_verify_paths failed.

Some string functions returned one or a combination of their parameters as their \ 
result. If one of the parameters had a non-ASCII character set, the result \ 
string had the same character set, resulting in incorrect behavior when an ASCII \ 
string was expected.

A null pointer dereference of a parser structure could occur during stored \ 
procedure name validation.

mysqld_multi displayed misleading error messages when it was unable to execute \ 
my_print_defaults.

Log message:
Remove the stability entity, it has no meaning outside of an official context.

Log message:
Change the service_bundle name to "export" to reduce diffs between the
original manifest.xml file and the output from "svccfg export".

Log message:
Add or fix manpath entries to use the correct path.

Changes 5.5.49:

Security Notes
--------------
MySQL client programs now support an --ssl-mode option that enables you to \ 
specify the security state of the connection to the server. The default value is \ 
DISABLED (establish an unencrypted connection). --ssl-mode=REQUIRED) can be \ 
specified to require a secure connection, or fail if a secure connection cannot \ 
be obtained.

These clients support --ssl-mode: mysql, mysqladmin, mysqlcheck, mysqldump, \ 
mysqlimport, mysqlshow, mysqlpump, mysqlslap, mysqltest, mysql_upgrade.

For more information, see Command Options for Secure Connections.

Bugs Fixed

Log message:
Bump PKGREVISION for security/openssl ABI bump.

Log message:
Changes 5.5.48:
* yaSSL was upgraded to version 2.3.9. This upgrade corrects an issue in which \ 
yaSSL handled only cases of zero or one leading zeros for the key agreement \ 
instead of potentially any number, which in rare cases could cause connections \ 
to fail when using DHE cipher suites.
* The Valgrind function signature in mysql-test/valgrind.supp was upgraded for \ 
Valgrind 3.11.
* Bugs Fixed

Log message:
Changes 5.5.47:
MySQL Server RPM packages now contain a conflict indicator for MySQL Connector \ 
C, such that an error occurs when installing MySQL Server if MySQL Connector C \ 
is also installed. To install MySQL Server, remove any MySQL Connector C \ 
packages first.

mysql_upgrade now attempts to print more informative errors than FATAL ERROR: \ 
Upgrade failed.

These client programs now support the --enable-cleartext-plugin option: \ 
mysqlcheck, mysqldump, mysqlimport, mysqlshow. This option enables the \ 
mysql_clear_password cleartext authentication plugin. (See The Cleartext \ 
Client-Side Authentication Plugin.)
