"An update for mariadb is now available for Red Hat Enterprise Linux 7.

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.

MariaDB is a multi-user, multi-threaded SQL database server that is
binary compatible with MySQL.

The following packages have been upgraded to a newer upstream version:
mariadb (5.5.52). (BZ#1304516, BZ#1377974)

Security Fix(es) :

* It was discovered that the MariaDB logging functionality allowed
writing to MariaDB 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)

* A race condition was found in the way MariaDB performed MyISAM
engine table repair. A database user with shell access to the server
running mysqld could use this flaw to change permissions of arbitrary
files writable by the mysql system user. (CVE-2016-6663)

* This update fixes several vulnerabilities in the MariaDB database
server. Information about these flaws can be found on the Oracle
Critical Patch Update Advisory page, listed in the References section.
