RHSA-2010:0825 - Moderate: mysql security update

Synopsis

Moderate: mysql security update

Type/Severity

Security Advisory Moderate

Topic

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.

Description

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.
