Unspecified vulnerability in Oracle MySQL 5.7.12 and earlier allows remote administrators to affect availability via vectors related to Server: Optimizer.

The version of MySQL installed on the remote host is 5.5.x prior to 5.5.50, 5.6.x prior to 5.6.31, or 5.7.x prior to 5.7.13. It is therefore affected by vulnerabilities in the following components :

 - Connection
 - Data Manipulation Language
 - Encryption
 - Full-Text Search
 - InnoDB
 - Optimizer
 - Parser
 - Privileges
 - Row-Based Replication
 - Replication
 - Types

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3040-1 advisory.

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

    MySQL has been updated to 5.5.50 in Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Ubuntu 15.10 has been updated     to MySQL 5.6.31. Ubuntu 16.04 LTS has been updated to MySQL 5.7.13.

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

    Please see the following for more information:

Oracle reports :

The quarterly Critical Patch Update contains 22 new security fixes for Oracle MySQL 5.5.49, 5.6.30, 5.7.13 and earlier

The version of MySQL running on the remote host is 5.7.x prior to 5.7.13. It is, therefore, affected by multiple vulnerabilities :

  - A heap buffer overflow condition exists in the     EVP_EncodeUpdate() function within file     crypto/evp/encode.c that is triggered when handling     a large amount of input data. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition. (CVE-2016-2105)

  - Multiple unspecified flaws exist in the Optimizer     subcomponent that allow an authenticated, remote     attacker to cause a denial of service condition.
    (CVE-2016-3424, CVE-2016-3440, CVE-2016-3501,     CVE-2016-3518)

  - An unspecified flaw exists in the Security: Encryption     subcomponent that allows an unauthenticated, remote     attacker to disclose sensitive information.
    (CVE-2016-3452)

  - Multiple unspecified flaws exist in the InnoDB     subcomponent that allow an authenticated, remote     attacker to cause a denial of service condition.
    (CVE-2016-3459, CVE-2016-5436)

  - An unspecified flaw exists in the Parser subcomponent     that allows a local attacker to gain elevated     privileges. (CVE-2016-3477)

  - An unspecified flaw exists in the FTS subcomponent that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2016-3486)

  - An unspecified flaw exists in the Types subcomponent     that allows an authenticated, remote attacker to cause     a denial of service condition. (CVE-2016-3521)

  - An unspecified flaw exists in the InnoDB subcomponent     that allows an authenticated, remote attacker to impact     integrity and confidentiality. (CVE-2016-3588)

  - Multiple unspecified flaws exist in the Security:
    Encryption subcomponent that allow an authenticated,     remote attacker to cause a denial of service condition.
    (CVE-2016-3614, CVE-2016-5442)

  - An unspecified flaw exists in the DML subcomponent that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2016-3615)

  - An unspecified flaw exists in the Log subcomponent that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2016-5437)

  - An unspecified flaw exists in the Privileges     subcomponent that allows an authenticated, remote     attacker to cause a denial of service condition.
    (CVE-2016-5439)

  - An unspecified flaw exists in the RBR subcomponent that     allows an authenticated, remote attacker to cause a     denial of service condition. (CVE-2016-5440)

  - An unspecified flaw exists in the Replication     subcomponent that allows an authenticated, remote     attacker to cause a denial of service condition.
    (CVE-2016-5441)

  - An unspecified flaw exists in the Connection     subcomponent that allows a local attacker to cause a     denial of service condition. (CVE-2016-5443)

  - An unspecified flaw exists in the Connection     subcomponent that allows an unauthenticated, remote     attacker to disclose sensitive information.
    (CVE-2016-5444)

  - An unspecified flaw exists in the InnoDB Plugin     subcomponent that allows an authenticated, remote     attacker to impact integrity. (CVE-2016-8288)

  - Multiple flaws exist in InnoDB that are triggered when     handling specially crafted 'ALTER TABLE' operations. An     authenticated, remote attacker can exploit these issues     to crash the database, resulting in a denial of service     condition.

  - Multiple overflow conditions exist due to improper     validation of user-supplied input. An authenticated,     remote attacker can exploit these issues to cause a     denial of service condition or the execution of     arbitrary code.

  - A NULL pointer dereference flaw exists in a parser     structure that is triggered during the validation of     stored procedure names. An authenticated, remote     attacker can exploit this to crash the database,     resulting in a denial of service condition.

  - Multiple overflow conditions exist in the InnoDB     memcached plugin due to improper validation of     user-supplied input. An authenticated, remote attacker     can exploit these issues to cause a denial of service     condition or the execution of arbitrary code.

  - An unspecified flaw exists that is triggered when     invoking Enterprise Encryption functions in multiple     threads simultaneously or after creating and dropping     them. An authenticated, remote attacker can exploit this     to crash the database, resulting in a denial of service     condition.

  - An unspecified flaw exists that is triggered when     handling a 'SELECT ... GROUP BY ... FOR UPDATE' query     executed with a loose index scan. An authenticated,     remote attacker can exploit this to crash the database,     resulting in a denial of service condition.

  - An unspecified flaw exists that is triggered when     performing a 'FLUSH TABLES' operation on a table with a     discarded tablespace. An authenticated, remote attacker     can exploit this to crash the database, resulting in a     denial of service condition.

  - A flaw exists in InnoDB that is triggered when     performing an 'OPTIMIZE TABLE' operation on a table with     a full-text index. An authenticated, remote attacker can     exploit this to crash the database, resulting in a     denial of service condition.

  - An unspecified flaw exists that is triggered when     performing an UPDATE operation on a generated virtual     BLOB column. An authenticated, remote attacker can     exploit this to crash the database, resulting in a     denial of service condition.

  - An unspecified flaw exists that is triggered when     performing a 'SHOW CREATE TABLE' operation on a table     with a generated column. An authenticated, remote     attacker can exploit this to crash the database,     resulting in a denial of service condition.
