MITIGATION

        Oracle states:
        
        "Due to the threat posed by a successful attack, Oracle
        strongly recommends that customers apply CPU fixes as soon
        as possible. Until you apply the CPU fixes, it may be
        possible to reduce the risk of successful attack by blocking
        network protocols required by an attack. For attacks that
        require certain privileges or access to certain packages,
        removing the privileges or the ability to access the
        packages from users that do not need the privileges may help
        reduce the risk of successful attack. Both approaches may
        break application functionality, so Oracle strongly
        recommends that customers test changes on non-production
        systems. Neither approach should be considered a long-term
        solution as neither corrects the underlying problem." [1]
