Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: X Plugin). Supported versions that are affected are 5.7.16 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: X Plugin). Supported versions     that are affected are 5.7.16 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. (CVE-2017-3646)

Note that Nessus relies on the presence of the package as reported by the vendor.

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.

    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)

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.

Please reference CVE/URL list for details

The version of MySQL running on the remote host is 5.7.x prior to 5.7.17. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the Security: Encryption     subcomponent that allows an authenticated, remote     attacker to cause a denial of service condition.
    (CVE-2016-8318)

  - An unspecified flaw exists in the Replication     subcomponent that allows an authenticated, remote     attacker to cause a denial of service condition.
    (CVE-2016-8327)

  - Multiple unspecified flaws exist in the Optimizer     subcomponent that allow an authenticated, remote     attacker to cause a denial of service condition.
    (CVE-2017-3238, CVE-2017-3251)

  - An unspecified flaw exists in the DML subcomponent that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3244)

  - An unspecified flaw exists in the Replication     subcomponent that allows an authenticated, remote     attacker to cause a denial of service condition.
    (CVE-2017-3256)

  - An unspecified flaw exists in the DDL subcomponent that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3258)

  - An unspecified flaw exists in the Packaging subcomponent     that allows a local attacker to impact confidentiality     and availability. (CVE-2017-3265)

  - An unspecified flaw exists in the DDL subcomponent that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3273)

  - Multiple unspecified flaws exist in the Packaging     subcomponent that allow a local attacker to gain     elevated privileges. (CVE-2017-3291, CVE-2017-3312)

  - An unspecified flaw exists in the MyISAM subcomponent     that allows a local attacker to disclose sensitive     information. (CVE-2017-3313)

  - An unspecified flaw exists in the Logging subcomponent     that allows a local attacker to cause a denial of     service condition. (CVE-2017-3317)

  - An unspecified flaw exists in the Error Handling     subcomponent that allows a local attacker to disclose     sensitive information. (CVE-2017-3318)

  - An unspecified flaw exists in the X Plugin subcomponent     that allows an authenticated, remote attacker to     disclose sensitive information. (CVE-2017-3319)

  - An unspecified flaw exists in the Security: Encryption     subcomponent that allows an authenticated, remote     attacker to disclose sensitive information.
    (CVE-2017-3320)

  - An unspecified flaw exists in the X Plugin subcomponent     that allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3646)

  - A local privilege escalation vulnerability exists in the     mysqld_safe component due to unsafe use of the 'rm' and     'chown' commands. A local attacker can exploit this to     gain elevated privileges.

  - An unspecified flaw exists in the mysqld_safe component     that allows an authenticated, remote attacker to have an     unspecified impact.

  - An overflow condition exists in the Optimizer component     due to improper validation of user-supplied input when     handling nested expressions. An authenticated, remote     attacker can exploit this to cause a stack-based buffer     overflow, resulting in a denial of service condition.

  - An unspecified flaw exists when handling a CREATE TABLE     query with a DATA DIRECTORY clause. An authenticated,     remote attacker can exploit this to gain elevated     privileges.
