  script_set_attribute(attribute:"description", value:
"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)");
