This may allow an authenticated attacker to cause a buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
 - A flaw exists that is triggered during the handling of prepared statements that use a parameter in the select list of a derived table that was part of a join.  This may allow an authenticated attacker to crash the server.
 - An unspecified flaw exists related to the Error Handling subcomponent. This may allow a local attacker to gain elevated privileges. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the MyISAM subcomponent. This may allow a local attacker to gain elevated privileges. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the DML subcomponent. This may allow an authenticated remote attacker to cause a denial of service. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the GIS subcomponent. This may allow an authenticated remote attacker to cause a denial of service. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the Optimizer subcomponent. This may allow an authenticated remote attacker to cause a denial of service. No further details have been provided by the vendor.

The version of MariaDB installed on the remote host is 10.0.x prior to 10.0.28, and is affected by multiple vulnerabilities :

 - An unspecified flaw may allow an authenticated attacker to bypass restrictions and create the '/var/lib/mysql/my.cnf' file with custom contents without the FILE privilege requirement.
 - A flaw in the C software version of AES Encryption and Decryption is triggered as table lookups do not properly consider cache-bank access times. This may allow a local user to disclose AES keys via a specially crafted application.
 - An unspecified flaw exists related to the MyISAM subcomponent. This may allow a local attacker to gain elevated privileges. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the DML subcomponent. This may allow an authenticated remote attacker to cause a denial of service. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the GIS subcomponent. This may allow an authenticated remote attacker to cause a denial of service. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the Optimizer subcomponent. This may allow an authenticated remote attacker to cause a denial of service. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the Federated subcomponent. This may allow an authenticated remote attacker to cause a denial of service. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the Security: Encryption subcomponent. This may allow an authenticated remote attacker to disclose potentially sensitive information. No further details have been provided by the vendor.
 - An unspecified flaw exists related to the Types subcomponent. This may allow an authenticated remote attacker to cause a denial of service. No further details have been provided by the vendor.
 - A flaw exists in the 'fill_alter_inplace_info()' function in 'sql/sql_table.cc' that is triggered when altering persistent virtual columns. This may allow an authenticated attacker to crash the database.
 - A flaw exists in the 'mysql_rm_table_no_locks()' function in 'sql/sql_table.cc' that is triggered during the handling of 'CREATE OR REPLACE TABLE' queries. This may allow an authenticated attacker to crash the database.
 - A flaw exists in 'scripts/mysqld_safe.sh' that is triggered when handling arguments to 'malloc-lib'.  This may allow a local attacker to potentially gain elevated privileges.  Note that CVE-2016-6664 is reportedly a duplicate assignment of CVE-2016-5617, which was assigned to this issue's manifestation in Oracle MySQL.

The version of MySQL installed on the remote host is version 5.6.x prior to 5.6.33 and is affected by multiple issues :

 - A flaw exists related to the way 'REPAIR TABLE' uses temporary files.  This may allow an authenticated attacker to gain elevated privileges.
 - A flaw exists in InnoDB that is triggered during the handling of an operation that dropped and created a full-text search table. This may allow an authenticated attacker to trigger an assertion and cause a denial of service.
