B.54. mysql
Updated mysql packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) associated with each description below.
MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries.
- CVE-2010-3840
- The MySQL PolyFromWKB() function did not sanity check Well-Known Binary (WKB) data, which could allow a remote, authenticated attacker to crash mysqld.
- CVE-2010-3839
- 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-2010-3838
- 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-2010-3837
- 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-2010-3836
- MySQL did not properly pre-evaluate LIKE arguments in view prepare mode, possibly allowing a remote, authenticated attacker to crash mysqld.
- CVE-2010-3835
- 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-2010-3833
- 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-2010-3683
- A flaw in the way MySQL handled LOAD DATA INFILE requests allowed MySQL to send OK packets even when there were errors.
- CVE-2010-3682
- A flaw in the way MySQL processed EXPLAIN statements for some complex SELECT queries could allow a remote, authenticated attacker to crash mysqld.
- CVE-2010-3681
- 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-2010-3680
- 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-2010-3679
- 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-2010-3678
- 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-2010-3677
- 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.
Note
Note that 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:
All MySQL users should upgrade to these updated packages, which correct these issues. After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.
