3. Description:

MySQL is a multi-user, multi-threaded SQL database server. It consists of
the MySQL server daemon, mysqld, and many client programs.

The following packages have been upgraded to a newer upstream version:
rh-mysql56-mysql (5.6.34).

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)

* A race condition was found in the way MySQL 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, CVE-2016-5616)

* A flaw was found in the way the mysqld_safe script handled creation of
error log file. The mysql operating system user could use this flaw to
escalate their privileges to root. (CVE-2016-6664, CVE-2016-5617)

* This update fixes several vulnerabilities in the MySQL database server.
Information about these flaws can be found on the Oracle Critical Patch
Update Advisory pages, listed in the References section. (CVE-2016-3492,
CVE-2016-5507, CVE-2016-5626, CVE-2016-5629, CVE-2016-8283)
