AFFECTED PRODUCTS AND VERSIONS:

        AIX 7.2, 7.3
        VIOS 3.1, 4.1

        The following fileset levels (VRMF) are vulnerable, if the
        respective Java version is installed:
        For Java8:    Less than 8.0.0.820

        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:

        IBM strongly recommends addressing the vulnerability now.
