    Summary: Improper Handling of Exceptional Conditions and Origin Validation Error in Eclipse Paho Java client library

    Details: In the Eclipse Paho Java client library version 1.2.0, when connecting to an MQTT server using TLS and setting a host name verifier, the result of that verification is not checked. This could allow one MQTT server to impersonate another and provide the client library with incorrect information.
