The ssl_verify_server_cert function in sql-common/client.c in Oracle MySQL 5.6.29 and earlier does not properly verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a '/CN=' string in a field in a certificate, as demonstrated by '/OU=/CN=bar.com/CN=foo.com'. (CVE-2016-2047)

Unspecified vulnerability in Oracle MySQL 5.6.29 and earlier allows remote attackers to affect confidentiality, integrity, and availability via vectors related to Pluggable Authentication. (CVE-2016-0639)

Unspecified vulnerability in Oracle MySQL 5.6.29 and earlier allows local users to affect availability via vectors related to FTS. (CVE-2016-0647)

Unspecified vulnerability in Oracle MySQL 5.6.29 and earlier allows local users to affect integrity and availability via vectors related to Federated. (CVE-2016-0642)

Unspecified vulnerability in Oracle MySQL 5.6.29 and earlier allows local users to affect confidentiality via vectors related to DML. (CVE-2016-0643)

Unspecified vulnerability in Oracle MySQL 5.6.29 and earlier allows local users to affect availability via vectors related to Security: Privileges. (CVE-2016-0666)

Unspecified vulnerability in Oracle MySQL 5.6.29 and earlier allows local users to affect availability via vectors related to PS. (CVE-2016-0648)
