The version of MySQL 5.0 installed on the remote host is earlier than 5.0.88. It is, therefore, potentially affected by the following vulnerabilities :

  - MySQL clients linked against OpenSSL are vulnerable     to man-in-the-middle attacks. (Bug #47320)

  - The GeomFromWKB() function can be manipulated     to cause a denial of service. (Bug #47780)

  - Specially crafted SELECT statements containing sub-     queries in the WHERE clause can cause the server     to crash. (Bug #48291)

  - It is possible to bypass access restrictions when the     data directory contains a symbolic link to a different     file system. (Bug #39277)

Updated mysql packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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 fix for the CVE-2009-4030 issue, a flaw in the way MySQL checked the paths used as arguments for the DATA DIRECTORY and INDEX DIRECTORY directives when the 'datadir' option was configured with a relative path, was incorrectly removed when the mysql packages in Red Hat Enterprise Linux 5 were updated to version 5.0.95 via RHSA-2012:0127. An authenticated attacker could use this flaw to bypass the restriction preventing the use of subdirectories of the MySQL data directory being used as DATA DIRECTORY and INDEX DIRECTORY paths. This update re-applies the fix for CVE-2009-4030.
(CVE-2012-4452)

Note: If the use of the DATA DIRECTORY and INDEX DIRECTORY directives were disabled as described in RHSA-2010:0109 (by adding 'symbolic-links=0' to the '[mysqld]' section of the 'my.cnf' configuration file), users were not vulnerable to this issue.

This issue was discovered by Karel Volny of the Red Hat Quality Engineering team.

This update also fixes the following bugs :

* Prior to this update, the log file path in the logrotate script did not behave as expected. As a consequence, the logrotate function failed to rotate the '/var/log/mysqld.log' file. This update modifies the logrotate script to allow rotating the mysqld.log file.
(BZ#647223)

* Prior to this update, the mysqld daemon could fail when using the EXPLAIN flag in prepared statement mode. This update modifies the underlying code to handle the EXPLAIN flag as expected. (BZ#654000)

* Prior to this update, the mysqld init script could wrongly report that mysql server startup failed when the server was actually started.
This update modifies the init script to report the status of the mysqld server as expected. (BZ#703476)

* Prior to this update, the '--enable-profiling' option was by default disabled. This update enables the profiling feature. (BZ#806365)

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.

The version of MySQL installed may be affected by a symlink-related restriction bypass vulnerability due to a CVE-2009-4030 regression fix being removed in a RedHat 5.0.95 package. 

Note that this flaw has no impact if the default basedir and datadir configuration values are unchanged.

The remote MiracleLinux 3 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2013-78:01 advisory.

    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. The base package     contains the MySQL client programs, the client shared libraries, and generic MySQL files.
    Security issues fixed with this release:
     CVE-2012-4452     MySQL 5.0.88, and possibly other versions and platforms, allows local users to bypass certain privilege     checks by calling CREATE TABLE on a MyISAM table with modified (1) DATA DIRECTORY or (2) INDEX DIRECTORY     arguments that are originally associated with pathnames without symlinks, and that can point to tables     created at a future time at which a pathname is modified to contain a symlink to a subdirectory of the     MySQL data home directory, related to incorrect calculation of the mysql_unpacked_real_data_home value.
    NOTE: this vulnerability exists because of a CVE-2009-4030 regression, which was not omitted in other     packages and versions such as MySQL 5.0.95.
    Fixed bugs:
     Previously, because the log file path in the logrotate script behaved unexpectedly, the logrotate     function failed to rotate the /var/log/mysqld.log file. This has been fixed.
     Previously, mysqld sometimes failed when using the EXPLAIN flag in prepared statement mode. This has been     fixed.
     Previously, the mysqld init script sometimes reported that mysql server startup had failed when it was     actually started. This has been fixed.
     Previously, the --enable-profiling option was disabled by default; it is now enabled.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
