It was found that the MySQL client library permitted but did not require a client to use SSL/TLS when establishing a secure connection to a MySQL server using the '--ssl' option. A man-in-the-middle attacker could use this flaw to strip the SSL/TLS protection from a connection between a client and a server. (CVE-2015-3152)

(CVE-2015-0501, CVE-2015-2568, CVE-2015-0499, CVE-2015-2571, CVE-2015-0433, CVE-2015-0441, CVE-2015-0505, CVE-2015-2573, CVE-2015-2582, CVE-2015-2620, CVE-2015-2643, CVE-2015-2648, CVE-2015-4737, CVE-2015-4752, CVE-2015-4757)

After installing this update, the MariaDB server daemon (mysqld) will be restarted automatically.

The MySQL Community Server edition was updated to 5.6.26, fixing security issues and bugs.

All changes:

  - Fixed CVEs: CVE-2015-2617, CVE-2015-2648, CVE-2015-2611,     CVE-2015-2582 CVE-2015-4752, CVE-2015-4756,     CVE-2015-2643, CVE-2015-4772 CVE-2015-4761,     CVE-2015-4757, CVE-2015-4737, CVE-2015-4771     CVE-2015-4769, CVE-2015-2639, CVE-2015-2620,     CVE-2015-2641 CVE-2015-2661, CVE-2015-4767

  - disable Performance Schema by default. Since MySQL 5.6.6     upstream enabled Performance Schema by default which     results in increased memory usage. The added option     disable Performance Schema again in order to decrease     MySQL memory usage [bnc#852477].

  - install INFO_BIN and INFO_SRC, noticed in MDEV-6912

  - remove superfluous '--group' parameter from     mysql-systemd-helper

  - make -devel package installable in the presence of     LibreSSL

  - cleanup after the update-message if it was displayed

  - add 'exec' to mysql-systemd-helper to shutdown     mysql/mariadb cleanly [bnc#943096]

The version of MariaDB installed on the remote host is prior to 10.0.20. It is, therefore, affected by multiple vulnerabilities as referenced in the 10.0.20 advisory.

  - Oracle MySQL before 5.7.3, Oracle MySQL Connector/C (aka libmysqlclient) before 6.1.3, and MariaDB before     5.5.44 use the --ssl option to mean that SSL is optional, which allows man-in-the-middle attackers to     spoof servers via a cleartext-downgrade attack, aka a BACKRONYM attack. (CVE-2015-3152)

  - Unspecified vulnerability in Oracle MySQL Server 5.5.43 and earlier and 5.6.24 and earlier allows remote     authenticated users to affect availability via vectors related to GIS. (CVE-2015-2582)

  - Unspecified vulnerability in Oracle MySQL Server 5.5.43 and earlier and 5.6.23 and earlier allows remote     authenticated users to affect confidentiality via unknown vectors related to Server : Security :
    Privileges. (CVE-2015-2620)

  - Unspecified vulnerability in Oracle MySQL Server 5.5.43 and earlier and 5.6.24 and earlier allows remote     authenticated users to affect availability via unknown vectors related to Server : Optimizer.
    (CVE-2015-2643)

  - Unspecified vulnerability in Oracle MySQL Server 5.5.43 and earlier and 5.6.24 and earlier allows remote     authenticated users to affect availability via vectors related to DML. (CVE-2015-2648)

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

Several issues have been discovered in the MySQL database server. The vulnerabilities are addressed by upgrading MySQL to the new upstream version 5.5.44. Please see the MySQL 5.5 Release Notes and Oracle's Critical Patch Update advisory for further details :

Updated mysql55-mysql packages that fix several security issues are now available for Red Hat Enterprise Linux 5.

Red Hat Product Security 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.

MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon (mysqld) and many client programs and libraries.

This update fixes several vulnerabilities in the MySQL database server. Information about these flaws can be found on the Oracle Critical Patch Update Advisory pages, listed in the References section. (CVE-2014-6568, CVE-2015-0374, CVE-2015-0381, CVE-2015-0382, CVE-2015-0391, CVE-2015-0411, CVE-2015-0432, CVE-2015-0433, CVE-2015-0441, CVE-2015-0499, CVE-2015-0501, CVE-2015-0505, CVE-2015-2568, CVE-2015-2571, CVE-2015-2573, CVE-2015-2582, CVE-2015-2620, CVE-2015-2643, CVE-2015-2648, CVE-2015-4737, CVE-2015-4752, CVE-2015-4757)

These updated packages upgrade MySQL to version 5.5.45. Refer to the MySQL Release Notes listed in the References section for a complete list of changes.

All MySQL users should upgrade to these updated packages, which correct these issues. After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.
