View as plain text  
Dear MySQL users,

MySQL Community Server 5.0.91, a new version of the popular Open Source
Database Management System, has been released.
Please note that the active maintenance of 5.0 has ended,and these
community builds are only provided because of the fixes to security bugs
# 50974, 53237, and 53371 as described below.

The release is now available in source and binary form for a number of
platforms from our archive download page at

   http://downloads.mysql.com/archives.php?p=mysql-5.0&v=5.0.91

Mirror service for MySQL server 5.0 has ended.
Also, support for some platforms with very low demand has ended.

Please bear in mind that MySQL 5.0 now receives extended support only,
and that all active development is happening on MySQL 5.1, 5.5, and
beyond. You will find the MySQL Lifecycle policy here:

    http://www.mysql.de/about/legal/lifecycle/

For your own best interest, we strongly recommend all current users of
MySQL 5.0 to upgrade to either MySQL 5.1 (current production release) or
MySQL 5.5 (pre-production release, adding new features in beta quality).

We welcome and appreciate your feedback, bug reports, bug fixes,
patches etc.:

    http://forge.mysql.com/wiki/Contributing

This section documents all changes and bugfixes that have been
applied since the last MySQL Community Server release (5.0.90).

Changes in MySQL 5.0.91 (05 May 2010)

Bugs fixed:

  * Security Fix: The server failed to check the table name
   argument of a COM_FIELD_LIST command packet for validity
   and compliance to acceptable table name standards. This
   could be exploited to bypass almost all forms of checks
   for privileges and table-level grants by providing a
   specially crafted table name argument to COM_FIELD_LIST.
   In MySQL 5.0 and above, this allowed an authenticated
   user with SELECT privileges on one table to obtain the
   field definitions of any table in all other databases and
   potentially of other MySQL instances accessible from the
   server's file system.
   Additionally, for MySQL version 5.1 and above, an
   authenticated user with DELETE or SELECT privileges on
   one table could delete or read content from any other
   table in all databases on this server, and potentially of
   other MySQL instances accessible from the server's file
   system.
   (Bug#53371: http://bugs.mysql.com/bug.php?id=53371,
   CVE-2010-1848
   (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-1848))

 * Security Fix: The server was susceptible to a
   buffer-overflow attack due to a failure to perform bounds
   checking on the table name argument of a COM_FIELD_LIST
   command packet. By sending long data for the table name,
   a buffer is overflown, which could be exploited by an
   authenticated user to inject malicious code.
   (Bug#53237: http://bugs.mysql.com/bug.php?id=53237,
   CVE-2010-1850
   (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-1850))

 * Security Fix: The server could be tricked into reading
   packets indefinitely if it received a packet larger than
   the maximum size of one packet.
   (Bug#50974: http://bugs.mysql.com/bug.php?id=50974,
   CVE-2010-1849
   (http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-1849))

 * The optimizer could attempt to evaluate the WHERE clause
   before any rows had been read, resulting in a server
   crash.
   (Bug#52177: http://bugs.mysql.com/bug.php?id=52177)

 * On Windows, LOAD_FILE() could cause a crash for some
   pathnames.
   (Bug#51893: http://bugs.mysql.com/bug.php?id=51893)

 * Use of HANDLER statements with tables that had spatial
   indexes caused a server crash.
   (Bug#51357: http://bugs.mysql.com/bug.php?id=51357)

 * With an XA transaction active, SET autocommit = 1 could
   cause side effects such as memory corruption or a server
   crash.
   (Bug#51342: http://bugs.mysql.com/bug.php?id=51342)

 * The SSL certificates in the test suite were about to
   expire. They have been updated with expiration dates in
   the year 2015.
   (Bug#50642: http://bugs.mysql.com/bug.php?id=50642)

 * For debug builds, an assertion was incorrectly raised in
   the optimizer when matching ORDER BY expressions.
   (Bug#50335: http://bugs.mysql.com/bug.php?id=50335)

 * The filesort sorting method applied to a CHAR(0) column
   could lead to a server crash.
   (Bug#49897: http://bugs.mysql.com/bug.php?id=49897)

 * sql_buffer_result had an effect on non-SELECT statements,
   contrary to the documentation.
   (Bug#49552: http://bugs.mysql.com/bug.php?id=49552)

 * EXPLAIN EXTENDED crashed trying to print column names for
   a subquery in the FROM clause when the table had gone out
   of scope.
   (Bug#49487: http://bugs.mysql.com/bug.php?id=49487)

 * mysql-test-run.pl now recognizes the
   MTR_TESTCASE_TIMEOUT, MTR_SUITE_TIMEOUT,
   MTR_SHUTDOWN_TIMEOUT, and MTR_START_TIMEOUT environment
   variables. If they are set, their values are used to set
   the --testcase-timeout, --suite-timeout,
   --shutdown-timeout, and --start-timeout options,
   respectively.
   (Bug#49210: http://bugs.mysql.com/bug.php?id=49210)

 * Certain INTERVAL expressions could cause a crash on
   64-bit systems.
   (Bug#48739: http://bugs.mysql.com/bug.php?id=48739)

 * The server crashed when it could not determine the best
   execution plan for queries involving outer joins with
   nondeterministic ON clauses such as the ones containing
   the RAND() function, a user-defined function, or a NOT
   DETERMINISTIC stored function.
   (Bug#48483: http://bugs.mysql.com/bug.php?id=48483)

 * If an outer query was invalid, a subquery might not even
   be set up. EXPLAIN EXTENDED did not expect this and
   caused a crash by trying to dereference improperly set up
   information.
   (Bug#48295: http://bugs.mysql.com/bug.php?id=48295)
