AFFECTED PRODUCTS AND VERSIONS:

    AIX 7.1, 7.2
    VIOS 2.2.x

    The following fileset levels (VRMF) are vulnerable, if the
    respective Java version is installed:
    For Java7:    Less than 7.0.0.645
    For Java7.1:  Less than 7.1.0.445
    For Java8:    Less than 8.0.0.535

    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.
