Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Optimizer). Supported versions that are affected are 5.7.18 and earlier. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.0 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:2886 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-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)

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

The version of MySQL installed on the remote host is version 5.7.x prior to 5.7.19 and is affected by an unspecified flaw exists that may allow an authenticated remote attacker to cause a denial of service. No further details have been provided by the vendor. (CVE-2017-3635)

Vulnerabilites also exists within the following components :

 - C API (CVE-2017-3650)
 - Charsets (CVE-2017-3648)
 - Client (CVE-2017-3651)
 - DDL (CVE-2017-3652, CVE-2017-3653)
 - DML (CVE-2017-3634, CVE-2017-3639, CVE-2017-3640, CVE-2017-3641, CVE-2017-3643, CVE-2017-3644)
 - Memcached (CVE-2017-3633)
 - Optimizer (CVE-2017-3638, CVE-2017-3642, CVE-2017-3645)

 - UDF (CVE-2017-3529)
 - X Plugin (CVE-2017-3637, CVE-2017-3646)

The version of MySQL running on the remote host is 5.7.x prior to 5.7.19. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the UDF component that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3529)

  - An unspecified flaw exists in the Memcached component     that allows an unauthenticated, remote attacker to     impact integrity and availability. (CVE-2017-3633)

  - Multiple unspecified flaws exist in the DML component     that allow an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3634,     CVE-2017-3639, CVE-2017-3640, CVE-2017-3641,     CVE-2017-3643, CVE-2017-3644, CVE-2017-10296)

  - An unspecified flaw exists in the Connector/C and C API     components that allow an authenticated, remote attacker     to cause a denial of service condition. (CVE-2017-3635)

  - Multiple unspecified flaws exist in the Optimizer     component that allow an authenticated, remote attacker     to cause a denial of service condition. (CVE-2017-3638,     CVE-2017-3642, CVE-2017-3645, CVE-2017-10279)

  - Multiple unspecified flaws exist in the Replication     component that allow an authenticated, remote attacker     to cause a denial of service condition. (CVE-2017-3647,     CVE-2017-3649)

  - An unspecified flaw exists in the Charsets component     that allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3648)

  - An unspecified flaw exists in the C API component that     allows an unauthenticated, remote attacker to disclose     sensitive information. (CVE-2017-3650)

  - An unspecified flaw exists in the Client mysqldump     component that allows an authenticated, remote attacker     to impact integrity. (CVE-2017-3651)

  - Multiple unspecified flaws exist in the DDL component     that allow an authenticated, remote attacker to impact     confidentiality and integrity. (CVE-2017-3652,     CVE-2017-3653)

  - An unspecified flaw exists in the OpenSSL Encryption     component that allows an unauthenticated, remote     attacker to cause a denial of service condition.
    (CVE-2017-3731)

  - An unspecified flaw exists in the Stored Procedure     component that allows an authenticated, remote attacker     to cause a denial of service condition. (CVE-2017-10284)

  - An unspecified flaw exists in the InnoDB component that     allows an authenticated, remote attacker to cause a     denial of service condition or to modify the contents of     the MySQL database. (CVE-2017-10365)
