Red Hat Security Advisory 2017-0184-01

Red Hat Security Advisory 2017-0184-01 - MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon and many client programs and libraries. Security Fix: 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.

3. Description:

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

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)

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 MySQL server daemon (mysqld) will be
restarted automatically.

5. Bugs fixed (https://bugzilla.redhat.com/):

1375198 - CVE-2016-6662 mysql: general_log can write to configuration files, leading to privilege escalation (CPU Oct 2016)
1378936 - CVE-2016-6663 CVE-2016-5616 mysql: race condition while setting stats during MyISAM table repair (CPU Oct 2016)
