The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:2130 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: mysql55-mysql (5.5.52).

    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)

    * This update fixes several vulnerabilities in the MySQL database server. Information about these flaws     can be found on the Oracle Critical Patch Update Advisory page, listed in the References section.
    (CVE-2016-3492, CVE-2016-5612, CVE-2016-5616, CVE-2016-5617, CVE-2016-5624, CVE-2016-5626, CVE-2016-5629,     CVE-2016-8283)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

遠端主機上安裝的 MySQL 5.5.x 版比 5.5.53 舊。因此，會受到多個弱點影響：- Optimizer 子元件中存在一個不明缺陷，會允許經驗證的遠端攻擊者造成拒絕服務情形。(CVE-2016-3492) - Security:Encryption 子元件中存在一個不明缺陷，經驗證的遠端攻擊者可藉以洩漏敏感資訊。(CVE-2016-5584) - MyISAM 子元件中存在一個不明缺陷，本機攻擊者可藉以取得提升的權限。(CVE-2016-5616) - Error Handling 子元件中存在一個不明缺陷，本機攻擊者可藉以取得提升的權限。(CVE-2016-5617) - GIS 子元件中存在一個不明缺陷，經驗證的遠端攻擊者可藉以造成拒絕服務情形。(CVE-2016-5626) - Federated 子元件中存在一個不明缺陷，經驗證的遠端攻擊者可藉以造成拒絕服務情形。(CVE-2016-5629) - 檔案 sql/sys_vars.cc 內的 check_log_path() 函式中存在一個缺陷，這是因為對於寫入至 my.cnf 組態檔案的能力限制不充分所致，其允許從非由目前版本使用的路徑位置載入組態檔案。經驗證的遠端攻擊者可惡意利用此問題，透過使用特製的查詢，利用記錄功能來建立新檔案或將自訂內容附加至現有檔案。這允許攻擊者插入使「malloc_lib=」指示詞指向特製 mysql_hookandroot_lib.so 檔案的自訂 .cnf 檔案，進而造成 MySQL 在下次啟動時載入惡意程式庫，來取得 root 權限。(CVE-2016-6662) - wolfSSL 中存在一個缺陷，尤其是在 AES 加密和解密的 C 軟體版本中，這是因為表格查詢未正確考量快取記憶庫存取時間所致。本機攻擊者可加以惡意利用，透過特製的應用程式洩漏 AES 金鑰。(CVE-2016-7440) - Types 子元件中存在一個不明缺陷，經驗證的遠端攻擊者可藉以造成拒絕服務情形。(CVE-2016-8283) 請注意，Nessus 並未測試這些問題，而是僅依據應用程式自我報告的版本號碼。

The version of MySQL installed on the remote host is version 5.5.x prior to 5.5.52 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.
 - An overflow condition exists that is triggered as certain input is not properly validated when handling long integer values in 'MEDIUMINT' columns.  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.
 - 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 Types 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.
 - A flaw exists in InnoDB that is triggered when accessing full-text search auxiliary tables while dropping the indexed table.  This may allow an authenticated attacker to trigger an assertion and cause a denial of service.
 - An overflow condition exists that is triggered as certain input is not properly validated when handling long integer values in 'MEDIUMINT' columns.  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 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 InnoDB 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 Types 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 MySQL installed on the remote host is version 5.7.x prior to 5.7.15 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.
 - A flaw exists in InnoDB that is triggered when accessing full-text search auxiliary tables while dropping the indexed table.  This may allow an authenticated attacker to trigger an assertion and cause a denial of service.
 - An overflow condition exists that is triggered as certain input is not properly validated when handling long integer values in 'MEDIUMINT' columns.  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 in the 'validate_password' plugin that is triggered as rejected passwords are logged in plaintext on the error log.  This may allow a local attacker to gain access to passwords that did not meet the password policy, but may potentially be very close to the password ultimately chosen and accepted.
 - A flaw exists in InnoDB that is triggered during the handling of an 'ALTER TABLE ... ENCRYPTION=Y, ALGORITHM=COPY' operation on a table residing in the system tablespace.  This may allow an authenticated attacker to crash the server.
 - 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. (CVE-2016-3492)
 - An unspecified flaw exists related to the InnoDB subcomponent. This may allow an authenticated remote attacker to cause a denial of service. No further details have been provided by the vendor. (CVE-2016-5507)
