It was found that the MySQL client library permitted but did not require a client to use SSL/TLS when establishing a secure connection to a MySQL server using the '--ssl' option. A man-in-the-middle attacker could use this flaw to strip the SSL/TLS protection from a connection between a client and a server. (CVE-2015-3152)

(CVE-2015-0501, CVE-2015-2568, CVE-2015-0499, CVE-2015-2571, CVE-2015-0433, CVE-2015-0441, CVE-2015-0505, CVE-2015-2573, CVE-2015-2582, CVE-2015-2620, CVE-2015-2643, CVE-2015-2648, CVE-2015-4737, CVE-2015-4752, CVE-2015-4757)

After installing this update, the MariaDB server daemon (mysqld) will be restarted automatically.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Unspecified vulnerability in Oracle MySQL Server 5.5.43 and earlier and 5.6.23 and earlier allows remote     authenticated users to affect confidentiality via unknown vectors related to Server : Security :
    Privileges. (CVE-2015-2620)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2674-1 advisory.

    Multiple security issues were discovered in MySQL and this update includes new upstream MySQL versions to     fix these issues.

    MySQL has been updated to 5.5.44 in Ubuntu 12.04 LTS, Ubuntu 14.04 LTS and Ubuntu 14.10. Ubuntu 15.04 has     been updated to MySQL 5.6.25.

    In addition to security fixes, the updated packages contain bug fixes, new features, and possibly     incompatible changes.

    Please see the following for more information:
    http://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-44.html     http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-25.html     http://www.oracle.com/technetwork/topics/security/cpujul2015-2367936.html

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

MySQL was updated to version 5.5.45, fixing bugs and security issues.

A list of all changes can be found on :

To fix the 'BACKRONYM' security issue (CVE-2015-3152) the behaviour of the SSL options was changed slightly to meet expectations: Now using '--ssl-verify-server-cert' and '--ssl[-*]' implies that the ssl connection is required. The mysql client will now print an error if ssl is required, but the server can not handle a ssl connection [bnc#924663], [bnc#928962], [CVE-2015-3152]

Additional bugs fixed :

  - fix rc.mysql-multi script to start instances after     restart properly [bnc#934401].

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