Updated mysql packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries.

It was found that the MySQL PolyFromWKB() function did not sanity check Well-Known Binary (WKB) data. A remote, authenticated attacker could use specially crafted WKB data to crash mysqld. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2010-3840)

A flaw was found in the way MySQL processed certain JOIN queries. If a stored procedure contained JOIN queries, and that procedure was executed twice in sequence, it could cause an infinite loop, leading to excessive CPU use (up to 100%). A remote, authenticated attacker could use this flaw to cause a denial of service. (CVE-2010-3839)

A flaw was found in the way MySQL processed queries that provide a mixture of numeric and longblob data types to the LEAST or GREATEST function. A remote, authenticated attacker could use this flaw to crash mysqld. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2010-3838)

A flaw was found in the way MySQL processed PREPARE statements containing both GROUP_CONCAT and the WITH ROLLUP modifier. A remote, authenticated attacker could use this flaw to crash mysqld. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2010-3837)

It was found that MySQL did not properly pre-evaluate LIKE arguments in view prepare mode. A remote, authenticated attacker could possibly use this flaw to crash mysqld. (CVE-2010-3836)

A flaw was found in the way MySQL processed statements that assign a value to a user-defined variable and that also contain a logical value evaluation. A remote, authenticated attacker could use this flaw to crash mysqld. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2010-3835)

A flaw was found in the way MySQL evaluated the arguments of extreme-value functions, such as LEAST and GREATEST. A remote, authenticated attacker could use this flaw to crash mysqld. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2010-3833)

A flaw was found in the way MySQL processed EXPLAIN statements for some complex SELECT queries. A remote, authenticated attacker could use this flaw to crash mysqld. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2010-3682)

A flaw was found in the way MySQL processed certain alternating READ requests provided by HANDLER statements. A remote, authenticated attacker could use this flaw to provide such requests, causing mysqld to crash. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2010-3681)

A flaw was found in the way MySQL processed CREATE TEMPORARY TABLE statements that define NULL columns when using the InnoDB storage engine. A remote, authenticated attacker could use this flaw to crash mysqld. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2010-3680)

A flaw was found in the way MySQL processed JOIN queries that attempt to retrieve data from a unique SET column. A remote, authenticated attacker could use this flaw to crash mysqld. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash. (CVE-2010-3677)

All MySQL users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.

Several vulnerabilities have been discovered in the MySQL database server. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2010-3677     It was discovered that MySQL allows remote authenticated     users to cause a denial of service (mysqld daemon crash)     via a join query that uses a table with a unique SET     column.

  - CVE-2010-3680     It was discovered that MySQL allows remote authenticated     users to cause a denial of service (mysqld daemon crash)     by creating temporary tables while using InnoDB, which     triggers an assertion failure.

  - CVE-2010-3681     It was discovered that MySQL allows remote authenticated     users to cause a denial of service (mysqld daemon crash)     by using the HANDLER interface and performing 'alternate     reads from two indexes on a table,' which triggers an     assertion failure.

  - CVE-2010-3682     It was discovered that MySQL incorrectly handled use of     EXPLAIN with certain queries. An authenticated user     could crash the server.

  - CVE-2010-3833     It was discovered that MySQL incorrectly handled     propagation during evaluation of arguments to     extreme-value functions. An authenticated user could     crash the server.

  - CVE-2010-3834     It was discovered that MySQL incorrectly handled     materializing a derived table that required a temporary     table for grouping. An authenticated user could crash     the server.

  - CVE-2010-3835     It was discovered that MySQL incorrectly handled certain     user-variable assignment expressions that are evaluated     in a logical expression context. An authenticated user     could crash the server.

  - CVE-2010-3836     It was discovered that MySQL incorrectly handled     pre-evaluation of LIKE predicates during view     preparation. An authenticated user could crash the     server.

  - CVE-2010-3837     It was discovered that MySQL incorrectly handled using     GROUP_CONCAT() and WITH ROLLUP together. An     authenticated user could crash the server.

  - CVE-2010-3838     It was discovered that MySQL incorrectly handled certain     queries using a mixed list of numeric and LONGBLOB     arguments to the GREATEST() or LEAST() functions. An     authenticated user could crash the server.

  - CVE-2010-3840     It was discovered that MySQL incorrectly handled     improper WKB data passed to the PolyFromWKB() function.
    An authenticated user could crash the server.

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
