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]
