MySQL 5.6.x < 5.6.33 Multiple Vulnerabilities

Synopsis
The remote database server is affected by multiple vulnerabilities.Description
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.
