RHEL 6 / 7 : rh-mysql56-mysql (RHSA-2017:2787)

medium Nessus Plugin ID 210269

Synopsis

The remote Red Hat host is missing one or more security updates for rh-mysql56-mysql.

Description

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2787 advisory.

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 Rohr 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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL rh-mysql56-mysql package based on the guidance in RHSA-2017:2787.
