mysql security update

CentOS Errata and Security Advisory CESA-2010:0825

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.
