RHEL 7 : mariadb-galera (RHSA-2016:2060)

critical Nessus Plugin ID 233051

Synopsis

The remote Red Hat host is missing a security update for mariadb-galera.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:2060 advisory.

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):

* 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#1376909)

* 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#1376903)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL mariadb-galera package based on the guidance in RHSA-2016:2060.
