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-mysql57-mysql (5.7.19).

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)
• 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)
• 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)
• 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-2017-3251, CVE-2017-3256, 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-2017-3319, CVE-2017-3320, CVE-2017-3331, CVE-2017-3450, CVE-2017-3453, CVE-2017-3454, CVE-2017-3455, CVE-2017-3456, CVE-2017-3457, CVE-2017-3458, CVE-2017-3459, CVE-2017-3460, CVE-2017-3461, CVE-2017-3462, CVE-2017-3463, CVE-2017-3464, CVE-2017-3465, CVE-2017-3467, CVE-2017-3468, CVE-2017-3529, CVE-2017-3633, CVE-2017-3634, CVE-2017-3637, CVE-2017-3638, CVE-2017-3639, CVE-2017-3640, CVE-2017-3641, CVE-2017-3642, CVE-2017-3643, CVE-2017-3644, CVE-2017-3645, CVE-2017-3646, CVE-2017-3647, CVE-2017-3648, CVE-2017-3649, CVE-2017-3650, CVE-2017-3651, CVE-2017-3652, CVE-2017-3653)

Bug Fix(es):

• Prior to this update, the scl macros were not set for the rh-mysql57-mysqld@.service file, which consequently made the service file unusable. This bug has been fixed, and rh-mysql57-mysqld@.service now works as expected. (BZ#1452511)
• 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#1452514)

Solution

After installing this update, the MySQL server daemon (mysqld) will be restarted automatically.
