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
For Java8: Less than 8.0.0.625
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.
