    https://vulners.com/cve/CVE-2019-11775
DESCRIPTION: Eclipse OpenJ9 could allow a local attacker to gain elevated
    privileges on the system, caused by an error where the loop versioner
    fails to privatize a value that is pulled out of the loop by 
    versioning. An attacker could exploit this vulnerability to corrupt
    memory and trigger an out-of-array-bounds and perform invalid actions.

AFFECTED PRODUCTS AND VERSIONS:

    AIX 7.1, 7.2
    VIOS 2.2, 3.1

    The following fileset levels (VRMF) are vulnerable, if the
    respective Java version is installed:
    For Java7:    Less than 7.0.0.650
    For Java7.1:  Less than 7.1.0.450
    For Java8:    Less than 8.0.0.540

    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
