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 later upstream version:
rh-mysql56-mysql (5.6.37).

Security Fix(es):

* An integer overflow flaw leading to a buffer overflow was found in the
way MySQL parsed connection handshake packets. An unauthenticated remote
attacker with access to the MySQL port could use this flaw to crash the
mysqld daemon. (CVE-2017-3599)

* It was discovered that the mysql and mysqldump tools did not correctly
handle database and table names containing newline characters. A database
user with privileges to create databases or tables could cause the mysql
command to execute arbitrary shell or SQL commands while restoring database
backup created using the mysqldump tool. (CVE-2016-5483, CVE-2017-3600)

* Multiple flaws were found in the way the MySQL init script handled
initialization of the database data directory and permission setting on the
error log file. The mysql operating system user could use these flaws to
escalate their privileges to root. (CVE-2017-3265)

* It was discovered that the mysqld_safe script honored the ledir option
value set in a MySQL configuration file. A user able to modify one of the
MySQL configuration files could use this flaw to escalate their privileges
to root. (CVE-2017-3291)

* It was discovered that the MySQL client command line tools only checked
after authentication whether server supported SSL. A man-in-the-middle
attacker could use this flaw to hijack client’s authentication to the
server even if the client was configured to require SSL connection.
(CVE-2017-3305)

* Multiple flaws were found in the way the mysqld_safe script handled
creation of error log file. The mysql operating system user could use these
flaws to escalate their privileges to root. (CVE-2017-3312)

* A flaw was found in the way MySQL client library (libmysqlclient) handled
prepared statements when server connection was lost. A malicious server or
a man-in-the-middle attacker could possibly use this flaw to crash an
application using libmysqlclient. (CVE-2017-3302)

* 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-2016-8327,
CVE-2017-3238, CVE-2017-3244, CVE-2017-3257, CVE-2017-3258, CVE-2017-3273,
CVE-2017-3308, CVE-2017-3309, CVE-2017-3313, CVE-2017-3317, CVE-2017-3318,
CVE-2017-3450, CVE-2017-3452, CVE-2017-3453, CVE-2017-3456, CVE-2017-3461,
CVE-2017-3462, CVE-2017-3463, CVE-2017-3464, CVE-2017-3633, CVE-2017-3634,
CVE-2017-3636, CVE-2017-3641, CVE-2017-3647, CVE-2017-3648, CVE-2017-3649,
CVE-2017-3651, CVE-2017-3652, CVE-2017-3653)

Red Hat would like to thank Pali Rohár for reporting CVE-2017-3305.

Bug Fix(es):

* Previously, the md5() function was blocked by MySQL in FIPS mode because
the MD5 hash algorithm is considered insecure. Consequently, the mysqld
daemon failed with error messages when FIPS mode was enabled. With this
update, md5() is allowed in FIPS mode for non-security operations. Note
that users are able to use md5() for security purposes but such usage is
not supported by Red Hat. (BZ#1452469)

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.
