1. Summary:

Updated mysql packages that fix various security issues, several bugs, and
add an enhancement are now available for Red Hat Enterprise Linux 4.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

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. MySQL is a
client/server implementation consisting of a server daemon (mysqld), and
many different client programs and libraries.

MySQL did not correctly check directories used as arguments for the DATA
DIRECTORY and INDEX DIRECTORY directives. Using this flaw, an authenticated
attacker could elevate their access privileges to tables created by other
database users. Note: this attack does not work on existing tables. An
attacker can only elevate their access to another user's tables as the
tables are created. As well, the names of these created tables need to be
predicted correctly for this attack to succeed. (CVE-2008-2079)

MySQL did not require the "DROP" privilege for "RENAME TABLE" statements.
An authenticated user could use this flaw to rename arbitrary tables.
(CVE-2007-2691)

MySQL allowed an authenticated user to access a table through a previously
created MERGE table, even after the user's privileges were revoked from the
original table, which might violate intended security policy. This is
addressed by allowing the MERGE storage engine to be disabled, which can be
done by running mysqld with the "--skip-merge" option. (CVE-2006-4031)

A flaw in MySQL allowed an authenticated user to cause the MySQL daemon to
crash via crafted SQL queries. This only caused a temporary denial of
service, as the MySQL daemon is automatically restarted after the crash.
(CVE-2006-3469)

As well, these updated packages fix the following bugs:

* in the previous mysql packages, if a column name was referenced more
than once in an "ORDER BY" section of a query, a segmentation fault
occurred.

* when MySQL failed to start, the init script returned a successful (0)
exit code. When using the Red Hat Cluster Suite, this may have caused
cluster services to report a successful start, even when MySQL failed to
start. In these updated packages, the init script returns the correct exit
codes, which resolves this issue.

* it was possible to use the mysqld_safe command to specify invalid port
numbers (higher than 65536), causing invalid ports to be created, and, in
some cases, a "port number definition: unsigned short" error. In these
updated packages, when an invalid port number is specified, the default
port number is used.

* when setting "myisam_repair_threads > 1", any repair set the index
cardinality to "1", regardless of the table size.

* the MySQL init script no longer runs "chmod -R" on the entire database
directory tree during every startup.

* when running "mysqldump" with the MySQL 4.0 compatibility mode option,
"--compatible=mysql40", mysqldump created dumps that omitted the
"auto_increment" field.

As well, the MySQL init script now uses more reliable methods for
determining parameters, such as the data directory location.

Note: these updated packages upgrade MySQL to version 4.1.22. For a full
list of bug fixes and enhancements, refer to the MySQL release notes:
http://dev.mysql.com/doc/refman/4.1/en/news-4-1-22.html

All mysql users are advised to upgrade to these updated packages, which
resolve these issues and add this enhancement.
