Multiple security issues were discovered in MySQL and this update includes new upstream MySQL versions to fix these issues.

MySQL has been updated to 5.5.54 in Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Ubuntu 16.04 LTS and Ubuntu 16.10 have been updated to MySQL 5.7.17.

In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.

Please see the following for more information:

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Oracle reports :

No further details have been provided in the Critical Patch Update

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.

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

The remote host is affected by the vulnerability described in GLSA-201702-17 (MySQL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in MySQL. Please review       the CVE identifiers referenced below for details.
  Impact :

    An attacker could possibly escalate privileges, gain access to critical       data or complete access to all MySQL server accessible data, or cause a       Denial of Service condition via unspecified vectors.
  Workaround :
