Red Hat Security Advisory 2016-2595-02 - 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. Security Fix: 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.

3. Description:

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. (CVE-2016-3492,
CVE-2016-5612, CVE-2016-5616, CVE-2016-5624, CVE-2016-5626, CVE-2016-5629,
CVE-2016-8283)

Additional Changes:

For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.3 Release Notes linked from the References section.

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/):

1138843 - dialog.so and mysql_clear_password.so should be in mariadb-libs package
1241623 - /usr/lib/tmpfiles.d/mariadb.conf is overwritten when mariadb package is updated
1300621 - Duplicate key with auto increment
1335863 - non-daemon ELF binaries are compiled as PIE, but without full RELRO
1375198 - CVE-2016-6662 mysql: general_log can write to configuration files, leading to privilege escalation
1378936 - CVE-2016-6663 mysql: race condition while setting stats during MyISAM table repair
