OVERVIEW

        Multiple vulnerabilities have been identified in Apache Impala prior
        to version 3.0.1. [1]


IMPACT

        Apache have provided the following details regarding the vulnerabilities:
        
        "CVE-2018-11785:
        - Missing authorization check in Apache Impala allows a
        Kerberos-authenticated but unauthorized user to inject random data into a
        running query, leading to wrong results for a query
        
        CVE-2018-11792 (IMPALA-7502):
        - ALTER TABLE/VIEW RENAME required ALTER on the old
        table. This may pose a potential security risk, such as having ALTER on a
        table and ALL on a particular database allows a user to move the table to a
        database with ALL, which will automatically grant that user with ALL
        privilege on that table due to the privilege inherited from the database
        " [1]


MITIGATION

        Apache recommends upgrading to the latest version of Apache Impala 
        to address these issues. [1]
