Several issues have been discovered in the MySQL database server. The vulnerabilities are addressed by upgrading MySQL to the new upstream version 5.5.55, which includes additional changes, such as performance improvements, bug fixes, new features, and possibly incompatible changes. Please see the MySQL 5.5 Release Notes and Oracle's Critical Patch Update advisory for further details :

https://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-55.html http://www.oracle.com/technetwork/security-advisory/cpuapr2017-3236618 .html

For Debian 7 'Wheezy', these problems have been fixed in version 5.5.55-0+deb7u1.

We recommend that you upgrade your mysql-5.5 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of MariaDB installed on the remote host is prior to 5.5.53. It is, therefore, affected by multiple vulnerabilities as referenced in the mariadb-5-5-53-release-notes advisory.

  - Unspecified vulnerability in Oracle MySQL 5.5.52 and earlier, 5.6.33 and earlier, and 5.7.15 and earlier     allows remote administrators to affect confidentiality via vectors related to Server: Security:
    Encryption. (CVE-2016-5584)

  - The C software implementation of AES Encryption and Decryption in wolfSSL (formerly CyaSSL) before 3.9.10     makes it easier for local users to discover AES keys by leveraging cache-bank timing differences.
    (CVE-2016-7440)

  - Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Client mysqldump). Supported     versions that are affected are 5.5.54 and earlier, 5.6.35 and earlier and 5.7.17 and earlier. Difficult to     exploit vulnerability allows high privileged attacker with network access via multiple protocols to     compromise MySQL Server. Successful attacks of this vulnerability can result in takeover of MySQL Server.
    Note: CVE-2017-3600 is equivalent to CVE-2016-5483. (CVE-2017-3600)

  - Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Client mysqldump). Supported     versions that are affected are 5.5.56 and earlier, 5.6.36 and earlier and 5.7.18 and earlier. Easily     exploitable vulnerability allows low privileged attacker with network access via multiple protocols to     compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized update,     insert or delete access to some of MySQL Server accessible data. (CVE-2017-3651)

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

An update for mariadb is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

MariaDB is a multi-user, multi-threaded SQL database server that is binary compatible with MySQL.

The following packages have been upgraded to a later upstream version:
mariadb (5.5.56). (BZ#1458933)

Security Fix(es) :

* It was discovered that the mysql and mysqldump tools did not correctly handle database and table names containing newline characters. A database user with privileges to create databases or tables could cause the mysql command to execute arbitrary shell or SQL commands while restoring database backup created using the mysqldump tool. (CVE-2016-5483, CVE-2017-3600)

* 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-2016-5617, CVE-2016-6664)

* Multiple flaws were found in the way the MySQL init script handled initialization of the database data directory and permission setting on the error log file. The mysql operating system user could use these flaws to escalate their privileges to root. (CVE-2017-3265)

* It was discovered that the mysqld_safe script honored the ledir option value set in a MySQL configuration file. A user able to modify one of the MySQL configuration files could use this flaw to escalate their privileges to root. (CVE-2017-3291)

* Multiple flaws were found in the way the mysqld_safe script handled creation of error log file. The mysql operating system user could use these flaws to escalate their privileges to root. (CVE-2017-3312)

* A flaw was found in the way MySQL client library (libmysqlclient) handled prepared statements when server connection was lost. A malicious server or a man-in-the-middle attacker could possibly use this flaw to crash an application using libmysqlclient.
(CVE-2017-3302)

* This update fixes several vulnerabilities in the MariaDB database server. Information about these flaws can be found on the Oracle Critical Patch Update Advisory page, listed in the References section.

The version of MariaDB running on the remote host is 10.1.x prior to 10.1.19. It is, therefore, affected by multiple vulnerabilities :

  - An unspecified flaw exists in the Security: Encryption     subcomponent that allows an authenticated, remote     attacker to disclose sensitive information.
    (CVE-2016-5584)

  - A flaw exists in wolfSSL, specifically within the C     software version of AES Encryption and Decryption, due     to table lookups not properly considering cache-bank     access times. A local attacker can exploit this, via a     specially crafted application, to disclose AES keys.
    Note that this vulnerability does not affect MariaDB     packages included in Red Hat products since they're     built against system OpenSSL packages. (CVE-2016-7440)

  - A flaw exists in the fill_alter_inplace_info() function     in sql_table.cc that is triggered when altering     persistent virtual columns. An authenticated, remote     attacker can exploit this to crash the database,     resulting in a denial of service condition.

  - A flaw exists in the mysql_rm_table_no_locks() function     in sql_table.cc that is triggered during the handling of     CREATE OR REPLACE TABLE queries. An authenticated,     remote attacker can exploit this to crash the database,     resulting in a denial of service condition.

  - A flaw exists in the buf_page_is_checksum_valid*     functions in buf0buf.cc that is triggered during the     handling of encrypted information. An authenticated,     remote attacker can exploit this to crash the database,     resulting in a denial of service condition.

  - A flaw exists in the wsrep_replicate_myisam     functionality that is triggered when dropping MyISAM     tables. An authenticated, remote attacker can exploit     this to crash the database, resulting in a denial of     service condition.
