Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect AIX

===============================================================================

SUMMARY:

There are multiple vulnerabilities in IBM SDK Java Technology Edition,
Versions 7, 7.1, 8 used by AIX. AIX has addressed the applicable CVEs.

===============================================================================

VULNERABILITY DETAILS:

CVEID: CVE-2022-3676
    https://vulners.com/cve/CVE-2022-3676
    https://vulners.com/cve/CVE-2022-3676
DESCRIPTION: Eclipse Openj9 could allow a remote attacker to bypass
    security restrictions, caused by improper runtime type check by the
    interface calls. By sending a specially-crafted request using 
    bytecode, an attacker could exploit this vulnerability to access or
    modify memory.
CVSS Base Score: 6.5
CVSS Temporal Score: See
    https://exchange.xforce.ibmcloud.com/vulnerabilities/239608

    https://vulners.com/cve/CVE-2021-28167
DESCRIPTION: Eclipse Openj9 could allow a remote attacker to bypass
    security restrictions, caused by a flaw in the 
    jdk.internal.reflect.ConstantPool API. By sending a specially-crafted
    request, an attacker could exploit this vulnerability to call static
    methods or access static members without running the class
    initialization method.

    https://vulners.com/cve/CVE-2022-21628
DESCRIPTION: Java SE is vulnerable to a denial of service, caused by a
    flaw in the Lightweight HTTP Server. By sending a specially-crafted
    request, a remote attacker could exploit this vulnerability to cause
    a denial of service condition.

    https://vulners.com/cve/CVE-2021-41041
    https://vulners.com/cve/CVE-2021-41041
DESCRIPTION: Eclipse Openj9 could allow a remote attacker to bypass
    security restrictions, caused by failing to throw the exception
    captured during bytecode verification when verification. By sending a
    specially-crafted request, an attacker could exploit this
    vulnerability to make unverified methods to be invoked using
    MethodHandles.

AFFECTED PRODUCTS AND VERSIONS:

    AIX 7.1, 7.2, 7.3
    VIOS 3.1

    The following fileset levels (VRMF) are vulnerable, if the
    respective Java version is installed:
    For Java7:    Less than 7.0.0.715
    For Java7.1:  Less than 7.1.0.515
    For Java8:    Less than 8.0.0.720

    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
