The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:2749 advisory.

    MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon, mysqld,     and many client programs.

    The following packages have been upgraded to a newer upstream version: rh-mysql56-mysql (5.6.34).

    Security Fix(es):

    * It was discovered that the MySQL logging functionality allowed writing to MySQL configuration files. An     administrative database user, or a database user with FILE privileges, could possibly use this flaw to run     arbitrary commands with root privileges on the system running the database server. (CVE-2016-6662)

    * A race condition was found in the way MySQL performed MyISAM engine table repair. A database user with     shell access to the server running mysqld could use this flaw to change permissions of arbitrary files     writable by the mysql system user. (CVE-2016-6663, CVE-2016-5616)

    * A flaw was found in the way the mysqld_safe script handled creation of error log file. The mysql     operating system user could use this flaw to escalate their privileges to root. (CVE-2016-6664,     CVE-2016-5617)

    * This update fixes several vulnerabilities in the MySQL database server. Information about these flaws     can be found on the Oracle Critical Patch Update Advisory pages, listed in the References section.
    (CVE-2016-3492, CVE-2016-5507, CVE-2016-5626, CVE-2016-5629, CVE-2016-8283)

The version of MySQL installed on the remote host is version 5.5.x prior to 5.5.53 and is affected by multiple issues :

 - 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. (CVE-2016-5584)
 - A flaw exists that may allow a local attacker with DBA permissions to gain elevated privileges. The issue is due to the program not properly restricting the ability to write to configuration files (e.g. my.cnf), combined with it loading a configuration file from specific locations that current versions do not use (e.g. /var/lib/mysql/my.cnf). This may allow an attacker to leverage specially crafted queries to use logging functionality to create new files or append custom content to existing files. By placing a custom .cnf file that MySQL will load, with a 'malloc_lib=' directive pointing to an attacker controlled 'mysql_hookandroot_lib.so' file, the attacker can cause MySQL to read the configuration file and load the malicious library the next time it starts. This can allow the attacker to gain root privileges. (CVE-2016-6662)

The version of MySQL installed on the remote host is version 5.7.x prior to 5.7.16 and is affected by multiple issues :

 - 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. (CVE-2016-5584)

MariaDB is a community-developed fork of the MySQL relational database.  The version of MariaDB installed on the remote host is 5.5.x earlier than 5.5.51, and is therefore affected by multiple vulnerabilities :

 - A denial of service vulnerability exists in the 'emb_stmt_execute()' function in file 'libmysqld/lib_sql.cc' when handling queries.  An authenticated, remote attacker can exploit this to crash the database.
 - A flaw in the 'check_log_path()' function in 'sql/sys_vars.cc' that may allow an authenticated attacker with DBA permissions to gain elevated privileges.  The issue is due to the program not properly restricting the ability to write to configuration files (e.g. my.cnf), combined with it loading a configuration file from specific locations that current versions do not use (e.g. '/var/lib/mysql/my.cnf').  This may allow an attacker to leverage specially crafted queries to use logging functionality to create new files or append custom content to existing files.  By placing a custom '.cnf' file that MySQL will load, with a 'malloc_lib=' directive pointing to an attacker controlled 'mysql_hookandroot_lib.so' file, the attacker can cause MySQL to read the configuration file and load the malicious library the next time it starts.  This can allow the attacker to gain root privileges.
 - A denial of service vulnerability exists in the 'st_select_lex_unit::cleanup()' function within file 'sql/sql_union.cc' when handling 'UNION' queries during 'JOIN' cleanup.  An authenticated, remote attacker can exploit this to crash the database.

The version of MySQL installed on the remote host is version 5.6.x prior to 5.6.34 and is affected by multiple issues :

MariaDB is a community-developed fork of the MySQL relational database. The version of MariaDB installed on the remote host is 10.0.x prior to 10.0.27, and is therefore affected by multiple DoS vulnerabilities :

 - A flaw exists in the 'emb_stmt_execute()' function in 'libmysqld/lib_sql.cc' that is triggered during the handling of queries. This may allow an authenticated attacker to crash the database.
 - A NULL pointer dereference flaw exists in the 'innobase_need_rebuild()' function that is triggered during the handling of renamed columns. This may allow an authenticated attacker to crash the database.
 - A flaw exists in the 'ha_myisam::enable_indexes()' function in 'storage/myisam/ha_myisam.cc' that is triggered during the handling of ALTER TABLE statements. This may allow an authenticated attacker to crash the database.
 - An unspecified flaw exists in the 'check_log_path()' function in 'sql/sys_vars.cc' that may allow an authenticated attacker to have an unspecified impact related to the 'general_log_file'. No further details have been provided.
 - A flaw exists in the 'Item_sum_std::val_real()' function in 'sql/item_sum.cc' that is triggered during the handling of SUM statements. This may allow an authenticated attacker to crash the database.
 - A flaw exists in the 'my_double_round()' function in 'sql/item_func.cc' that is triggered during the handling of specially crafted queries. This may allow an authenticated attacker to crash the database.
 - A denial of service vulnerability exists in the 'st_select_lex_unit::cleanup()' function within file 'sql/sql_union.cc' when handling 'UNION' queries during 'JOIN' cleanup.  An authenticated, remote attacker can exploit this to crash the database.

MariaDB is a community-developed fork of the MySQL relational database. The version of MariaDB installed on the remote host is 10.1.x earlier than 10.1.17, and is therefore affected by multiple vulnerabilities :

 - A NULL pointer dereference flaw exists in the 'innobase_need_rebuild()' function that is triggered during the handling of renamed columns. This may allow an authenticated attacker to crash the database.
 - A flaw exists in the 'ha_myisam::enable_indexes()' function in 'storage/myisam/ha_myisam.cc' that is triggered during the handling of ALTER TABLE statements. This may allow an authenticated attacker to crash the database.
 - An unspecified flaw exists in the 'check_log_path()' function in 'sql/sys_vars.cc' that may allow an authenticated attacker to have an unspecified impact related to the 'general_log_file'. No further details have been provided.
 - A flaw exists in the 'Item_sum_std::val_real()' function in 'sql/item_sum.cc' that is triggered during the handling of SUM statements. This may allow an authenticated attacker to crash the database.
 - A flaw exists in 'sql/item_subselect.cc' that is triggered during the handling of specially crafted queries for non-existent functions.  This may allow an authenticated attacker to crash the database.
 - A flaw exists in the 'Item_subselect::is_expensive()' function in 'sql/item_subselect.cc' that is triggered during the handling of optimization procedures.  This may allow an authenticated attacker to crash the database.
 - A flaw exists in the 'st_select_lex_unit::cleanup()' function in 'sql/sql_union.cc' that is triggered during the handling of 'UNION' queries during 'JOIN' cleanup.  This may allow an authenticated attacker to crash the database.
