Unspecified vulnerability in Oracle MySQL 5.6.20 and earlier allows remote authenticated users to affect availability via unknown vectors related to Types.

The version of MySQL installed on the remote host is version 5.6.x prior to 5.6.27 and is affected by multiple unspecified flaws related the following subcomponents :
 - Security:Firewall (CVE-2015-4766)
 - Security:Privileges (CVE-2015-4791)
 - Server Optimizer (CVE-2015-4800)
 - Server Partition (CVE-2015-4833)
 - DML (CVE-2015-4862, CVE-2015-4905)
 - InnoDB (CVE-2015-4866, CVE-2015-4895)
 - Replication (CVE-2015-4890)
 - libmysqld (CVE-2015-4904)
 - Memcached (CVE-2015-4910)

These flaws may allow an authenticated attacker to cause a denial of service.

Addditionally, an unspecified vulnerability flaw allows remote authenticated users to affect availability via unknown vectors related to Types.  No further detailes have been provided by the vendor about these vulnerabilities.

The mysql package was updated to version 5.5.46 to fixs several security and non security issues.

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.

MySQL was updated to 5.6.27 to fix security issues and bugs.

The following vulnerabilities were fixed as part of the upstream release [boo#951391]: CVE-2015-1793, CVE-2015-0286, CVE-2015-0288, CVE-2015-1789, CVE-2015-4730, CVE-2015-4766, CVE-2015-4792, CVE-2015-4800, CVE-2015-4802, CVE-2015-4815, CVE-2015-4816, CVE-2015-4819, CVE-2015-4826, CVE-2015-4830, CVE-2015-4833, CVE-2015-4836, CVE-2015-4858, CVE-2015-4861, CVE-2015-4862, CVE-2015-4864, CVE-2015-4866, CVE-2015-4870, CVE-2015-4879, CVE-2015-4890, CVE-2015-4895, CVE-2015-4904, CVE-2015-4905, CVE-2015-4910, CVE-2015-4913

Details on these and other changes can be found at:
http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-27.html

The following security relevant changes are included additionally :

  - CVE-2015-3152: MySQL lacked SSL enforcement. 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 [boo#924663], [boo#928962]

The version of Oracle MySQL installed on the remote host is 5.6.x prior to 5.6.21. It is, therefore, affected by a unspecified denial of service vulnerability in the Types subcomponent, which can be exploited by an authenticated, remote attacker.

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2781-1 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 5.5.46 in Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Ubuntu 15.04 and Ubuntu 15.10     have been updated to MySQL 5.6.27.

    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-5-5-45.html     http://dev.mysql.com/doc/relnotes/mysql/5.5/en/news-5-5-46.html     http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-26.html     http://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-27.html     http://www.oracle.com/technetwork/topics/security/cpuoct2015-2367953.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.

The version of MySQL running on the remote host is 5.6.x prior to 5.6.27. It is, therefore, potentially affected by the following vulnerabilities :

  - A certificate validation bypass vulnerability exists in     the Security:Encryption subcomponent due to a flaw in     the X509_verify_cert() function in x509_vfy.c that is     triggered when locating alternate certificate chains     when the first attempt to build such a chain fails. A     remote attacker can exploit this, by using a valid leaf     certificate as a certificate authority (CA), to issue     invalid certificates that will bypass authentication.
    (CVE-2015-1793)

  - An unspecified flaw exists in the Client Programs     subcomponent. A local attacker can exploit this to gain     elevated privileges. (CVE-2015-4819)

  - An unspecified flaw exists in the Types subcomponent.
    An authenticated, remote attacker can exploit this to     gain access to sensitive information. (CVE-2015-4826)

  - An unspecified flaws exist in the Security:Privileges     subcomponent. An authenticated, remote attacker can     exploit these to impact integrity. (CVE-2015-4830,     CVE-2015-4864)

  - An unspecified flaw exists in the DLM subcomponent.
    An authenticated, remote attacker can exploit this to     impact integrity. (CVE-2015-4879)

  - An unspecified flaw exists in the Server Security     Encryption subcomponent that allows an authenticated,     remote attacker to disclose sensitive information.
    (CVE-2015-7744)

Additionally, unspecified denial of service vulnerabilities can also exist in the following MySQL subcomponents :

  - DDL (CVE-2015-4815)

  - DML (CVE-2015-4858, CVE-2015-4862, CVE-2015-4905,     CVE-2015-4913)

  - InnoDB (CVE-2015-4861, CVE-2015-4866, CVE-2015-4895)

  - libmysqld (CVE-2015-4904)

  - Memcached (CVE-2015-4910)

  - Optimizer (CVE-2015-4800)

  - Parser (CVE-2015-4870)

  - Partition (CVE-2015-4792, CVE-2015-4802, CVE-2015-4833)

  - Query (CVE-2015-4807)

  - Replication (CVE-2015-4890)

  - Security : Firewall (CVE-2015-4766)

  - Server : General (CVE-2016-0605)

  - Security : Privileges (CVE-2015-4791)

  - SP (CVE-2015-4836)

  - Types (CVE-2015-4730)
