CVE-2018-11792

In Apache Impala before 3.0.1, 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.

En Apache Impala en versiones anteriores a la 3.0.1, ALTER TABLE/VIEW RENAME requería ALTER en la tabla vieja. Esto podría suponer un riesgo potencial de seguridad, como tener ALTER en una tabla y ALL en una base de datos en concreto, que permite que un usuario mueva la tabla a una base de datos con ALL. Esto otorgará automáticamente al usuario el privilegio ALL en esa tabla debido a que se hereda el privilegios de la base de datos.
