"The version of MySQL running on the remote host is 5.6.x prior to
5.6.33. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the InnoDB subcomponent
    that allows an authenticated, remote attacker to cause a
    denial of service condition. (CVE-2016-5507)

  - A flaw exists in the check_log_path() function within
    file sql/sys_vars.cc due to inadequate restrictions on
    the ability to write to the my.cnf configuration file
    and allowing the loading of configuration files from
    path locations not used by current versions. An
    authenticated, remote attacker can exploit this issue
    by using specially crafted queries that utilize logging
    functionality to create new files or append custom
    content to existing files. This allows the attacker to
    gain root privileges by inserting a custom .cnf file
    with a 'malloc_lib=' directive pointing to specially
    crafted mysql_hookandroot_lib.so file and thereby cause
    MySQL to load a malicious library the next time it is
    started. (CVE-2016-6662)

  - An unspecified flaw exists that allows an authenticated,
    remote attacker to bypass restrictions and create the
    /var/lib/mysql/my.cnf file with custom contents without
    the FILE privilege requirement. (CVE-2016-6663)

  - A flaw exists that is related to the use of temporary
    files by REPAIR TABLE. An authenticated, remote attacker
    can exploit this to gain elevated privileges.

  - A flaw exists in InnoDB when handling an operation that
    dropped and created a full-text search table. An
    authenticated, remote attacker can exploit this to
    trigger an assertion, resulting in a denial of service
    condition.

  - A flaw exists in InnoDB when accessing full-text
    auxiliary tables while dropping the indexed table. An
    authenticated, remote attacker can exploit this to
    trigger an assertion, resulting in a denial of service
    condition.

  - A buffer overflow condition exists when handling long
    integer values in MEDIUMINT columns due to the improper
    validation of certain input. An authenticated, remote
    attacker can exploit this to cause a denial of service
    condition or the execution of arbitrary code.

  - An unspecified flaw exists due to how a prepared
    statement uses a parameter in the select list of a
    derived table that was part of a join. An authenticated,
    remote attacker can exploit this to cause a server exit,
    resulting in a denial of service condition.

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