Red Hat Security Advisory

 

Synopsis: Important: mariadb-galera security and bug fix update

Advisory ID: RHSA-2016:2077-01

Product: Red Hat Enterprise Linux OpenStack Platform

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-2077.html

Issue date: 2016-10-18

CVE Names: CVE-2016-6662

=====================================================================

 

1. Summary:

 

An update for mariadb-galera is now available for Red Hat OpenStack

Platform 8.0 (Liberty).

 

Red Hat Product Security has rated this update as having a security impact

of Important. A Common Vulnerability Scoring System (CVSS) base score,

which gives a detailed severity rating, is available for each vulnerability

from the CVE link(s) in the References section.

 

2. Relevant releases/architectures:

 

Red Hat OpenStack Platform 8.0 (Liberty) - x86_64

 

3. Description:

 

MariaDB is a multi-user, multi-threaded SQL database server that is binary

compatible with MySQL. Galera is a synchronous multi-master cluster for

MariaDB.

 

Security Fix(es):

 

* It was discovered that the MySQL logging functionality allowed writing to

MySQL configuration files. An administrative database user, or a database

user with FILE privileges, could possibly use this flaw to run arbitrary

commands with root privileges on the system running the database server.

(CVE-2016-6662)

 

Bug Fix(es):

 

* Previously, both the mariadb-server and mariadb-galera-server packages

shipped the client-facing libraries, dialog.so and mysql_clear_password.so.

As a result, the mariadb-galera-server package would fail to install

because of package conflicts. With this update, these libraries have been

moved from mariadb-galera-server to mariadb-libs, and the

mariadb-galera-server package installs successfully. (BZ#1376905)

 

* Because Red Hat Enterprise Linux 7.3 changed the return format of the

"systemctl is-enabled" command as consumed by shell scripts, the

mariadb-galera RPM package, upon installation, erroneously detected that

the MariaDB service was enabled when it was not. As a result, the Red Hat

OpenStack Platform installer, which then tried to run mariadb-galera using

Pacemaker and not systemd, failed to start Galera. With this update,

mariadb-galera's RPM installation scripts now use a different systemctl

command, correctly detecting the default MariaDB as disabled, and the

installer can succeed. (BZ#1376913)

 

4. Solution:

 

For details on how to apply this update, which includes the changes

described in this advisory, refer to:

 

https://access.redhat.com/articles/11258

 

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

restarted automatically.

 

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

 

1375198 - CVE-2016-6662 mysql: general_log can write to configuration files, leading to privilege escalation

1376905 - RHEL 7.3 upgrades fails on upgrade because of mariadb-libs package conflict.

1376913 - mysqld service prevents haproxy to get started and deployment fails
