(Red Hat Issues Fix) MySQL Multiple Flaws Let Remote Authenticated Users Deny Service
SecurityTracker Alert ID:  1024677
SecurityTracker URL:  http://securitytracker.com/id/1024677
CVE Reference:   CVE-2010-3840   (Links to External Site)
Date:  Nov 3 2010
Impact:   Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 5.1.51
Description:   Multiple vulnerabilities were reported in MySQL. A remote authenticated user can cause denial of service conditions.

A remote authenticated user can send specially crafted data to cause the target service to crash.

Errors in the evaluation of arguments to extreme-value functions (e.g., LEAST(), GREATEST()) can trigger a crash.

A derived table that requires a temporary table for grouping can trigger a crash.

When a user-variable assignment expression is used in certain situations, a crash may occur.

A pre-evaluation of LIKE predicates during view preparation can trigger a crash.

A GROUP_CONCAT() and WITH ROLLUP function (called together) can trigger a crash.

A request including the GREATEST() or LEAST() functions with a mixed list of numeric and LONGBLOB arguments can trigger a crash when the results of such a function is processed using an intermediate temporary table.

Queries with nested joins from stored procedures and prepared statements can cause the system to enter an infinite loop.

Specially crafted WKB data can cause the PolyFromWKB() function to crash.
Impact:   A remote authenticated user can cause the target service to crash or enter an infinite loop.
Solution:   Red Hat has issued a fix for CVE-2010-3840.

The Red Hat advisory is available at:

=====================================================================
                   Red Hat Security Advisory

Synopsis:          Moderate: mysql security update
Advisory ID:       RHSA-2010:0824-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2010-0824.html
Issue date:        2010-11-03
CVE Names:         CVE-2010-1848 CVE-2010-3681 CVE-2010-3840 
=====================================================================

1. Summary:

Updated mysql packages that fix three security issues are now available for
Red Hat Enterprise Linux 4.

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. 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 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 directory traversal flaw was found in the way MySQL handled the
parameters of the MySQL COM_FIELD_LIST network protocol command. A remote,
authenticated attacker could use this flaw to obtain descriptions of the
fields of an arbitrary table using a request with a specially-crafted
table name. (CVE-2010-1848)

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259

5. Bugs fixed (http://bugzilla.redhat.com/):

592079 - CVE-2010-1848 mysql: multiple insufficient table name checks
628680 - CVE-2010-3681 MySQL: mysqld DoS (assertion failure) by alternate reads from two indexes on a table using the HANDLER interface (MySQL bug #54007)
640865 - CVE-2010-3840 MySQL: crash when loading data into geometry function PolyFromWKB() (MySQL Bug#51875)
