====================================================================
1. Summary:

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

The Red Hat Security Response Team has rated this update as having
important 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:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, 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.

A buffer overflow flaw was found in the way MySQL handled the parameters of
the MySQL COM_FIELD_LIST network protocol command (this command is sent
when a client uses the MySQL mysql_list_fields() client library function).
An authenticated database user could send a request with an excessively
long table name to cause a temporary denial of service (mysqld crash) or,
potentially, execute arbitrary code with the privileges of the database
server. (CVE-2010-1850)

A directory traversal flaw was found in the way MySQL handled the
parameters of the MySQL COM_FIELD_LIST network protocol command. An
authenticated database user 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)

A flaw was discovered in the way MySQL handled symbolic links to tables
created using the DATA DIRECTORY and INDEX DIRECTORY directives in CREATE
TABLE statements. An attacker with CREATE and DROP table privileges, and
shell access to the database server, could use this flaw to remove data and
index files of tables created by other database users using the MyISAM
storage engine. (CVE-2010-1626)

All MySQL users are advised to upgrade to these updated packages, which
contain backported patches to resolve 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
