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 InnoDB subcomponent     that allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2017-3257)

  - 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.
