Multiple security issues were discovered in MySQL and this update includes new upstream MySQL versions to fix these issues.

MySQL has been updated to 5.1.61 in Ubuntu 10.04 LTS, Ubuntu 10.10, Ubuntu 11.04 and Ubuntu 11.10. Ubuntu 8.04 LTS has been updated to MySQL 5.0.95.

In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.

Please see the following for more information :

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The MySQL PolyFromWKB() function did not sanity check Well-Known Binary (WKB) data, which could allow a remote, authenticated attacker to crash mysqld. (CVE-2010-3840)

A flaw in the way MySQL processed certain JOIN queries could allow a remote, authenticated attacker to cause excessive CPU use (up to 100%), if a stored procedure contained JOIN queries, and that procedure was executed twice in sequence. (CVE-2010-3839)

A flaw in the way MySQL processed queries that provide a mixture of numeric and longblob data types to the LEAST or GREATEST function, could allow a remote, authenticated attacker to crash mysqld.
(CVE-2010-3838)

A flaw in the way MySQL processed PREPARE statements containing both GROUP_CONCAT and the WITH ROLLUP modifier could allow a remote, authenticated attacker to crash mysqld. (CVE-2010-3837)

MySQL did not properly pre-evaluate LIKE arguments in view prepare mode, possibly allowing a remote, authenticated attacker to crash mysqld. (CVE-2010-3836)

A flaw in the way MySQL processed statements that assign a value to a user-defined variable and that also contain a logical value evaluation could allow a remote, authenticated attacker to crash mysqld.
(CVE-2010-3835)

A flaw in the way MySQL evaluated the arguments of extreme-value functions, such as LEAST and GREATEST, could allow a remote, authenticated attacker to crash mysqld. (CVE-2010-3833)

A flaw in the way MySQL handled LOAD DATA INFILE requests allowed MySQL to send OK packets even when there were errors. (CVE-2010-3683)

A flaw in the way MySQL processed EXPLAIN statements for some complex SELECT queries could allow a remote, authenticated attacker to crash mysqld. (CVE-2010-3682)

A flaw in the way MySQL processed certain alternating READ requests provided by HANDLER statements could allow a remote, authenticated attacker to crash mysqld. (CVE-2010-3681)

A flaw in the way MySQL processed CREATE TEMPORARY TABLE statements that define NULL columns when using the InnoDB storage engine, could allow a remote, authenticated attacker to crash mysqld.
(CVE-2010-3680)

A flaw in the way MySQL processed certain values provided to the BINLOG statement caused MySQL to read unassigned memory. A remote, authenticated attacker could possibly use this flaw to crash mysqld.
(CVE-2010-3679)

A flaw in the way MySQL processed SQL queries containing IN or CASE statements, when a NULL argument was provided as one of the arguments to the query, could allow a remote, authenticated attacker to crash mysqld. (CVE-2010-3678)

A flaw in the way MySQL processed JOIN queries that attempt to retrieve data from a unique SET column could allow a remote, authenticated attacker to crash mysqld. (CVE-2010-3677)

Note: CVE-2010-3840, CVE-2010-3838, CVE-2010-3837, CVE-2010-3835, CVE-2010-3833, CVE-2010-3682, CVE-2010-3681, CVE-2010-3680, CVE-2010-3678, and CVE-2010-3677 only cause a temporary denial of service, as mysqld was automatically restarted after each crash.

These updated packages upgrade MySQL to version 5.1.52. Refer to the MySQL release notes for a full list of changes :

http://dev.mysql.com/doc/refman/5.1/en/news-5-1-52.html

After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.

Multiple vulnerabilities were discovered and corrected in mysql :

  - During evaluation of arguments to extreme-value     functions (such as LEAST() and GREATEST()), type errors     did not propagate properly, causing the server to crash     (CVE-2010-3833).

  - The server could crash after materializing a derived     table that required a temporary table for grouping     (CVE-2010-3834).

  - 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 (CVE-2010-3835).

  - Pre-evaluation of LIKE predicates during view     preparation could cause a server crash (CVE-2010-3836).

  - GROUP_CONCAT() and WITH ROLLUP together could cause a     server crash (CVE-2010-3837).

  - 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     (CVE-2010-3838).

  - Queries with nested joins could cause an infinite loop     in the server when used from stored procedures and     prepared statements (CVE-2010-3839).

  - The PolyFromWKB() function could crash the server when     improper WKB data was passed to the function     (CVE-2010-3840).

The updated packages have been patched to correct these issues.

This update fixes the following security issue :

  - 676974: mysql-cluster: security issues fixed in MySQL     5.1.51

This update also fixes the following non-security issue :

  - 635645: mysql init script fails to start when SELinux is     enabled
