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.
