AFFECTED PRODUCTS AND VERSIONS:

        AIX 7.1, 7.2
        VIOS 3.1

        The following fileset levels (VRMF) are vulnerable, if the
        respective Java version is installed:
        For Java7:    Less than 7.0.0.680
        For Java7.1:  Less than 7.1.0.480

        Note: To find out whether the affected Java filesets are installed
        on your systems, refer to the lslpp command found in AIX user's guide.

        Example:  lslpp -L | grep -i java


REMEDIATION:

        Note: Recommended remediation is to always install the most recent
        Java package available for the respective Java version.
