VULNERABILITY DETAILS:

    CVEID: CVE-2022-40609
        https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-40609
    DESCRIPTION: IBM SDK, Java Technology Edition 7.1.5.18 and 8.0.8.0 could
        allow a remote attacker to execute arbitrary code on the system,
        caused by an unsafe deserialization flaw. By sending specially-crafted
        data, an attacker could exploit this vulnerability to execute
        arbitrary code on the system. IBM X-Force ID: 236069.
    CVSS Base Score: 8.1
    CVSS Temporal Score: See
        https://exchange.xforce.ibmcloud.com/vulnerabilities/236069
        for the current score
    CVSS Environmental Score*: Undefined
    CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

    CVEID: CVE-2023-22049
        https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-22049
    DESCRIPTION: An unspecified vulnerability in Java SE related to the
        Libraries component could allow a remote attacker to cause low
        integrity impacts.
    CVSS Base Score: 3.7
    CVSS Temporal Score: See
        https://exchange.xforce.ibmcloud.com/vulnerabilities/261048
        for the current score
    CVSS Environmental Score*: Undefined
    CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)


AFFECTED PRODUCTS AND VERSIONS:

        AIX 7.2, 7.3
        VIOS 3.1

        The following fileset levels (VRMF) are vulnerable, if the
        respective Java version is installed:
        For Java8:    Less than 8.0.0.810

        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.

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