    Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

      CVE-2023-21930:
      Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE
    (component: JSSE). Supported versions that are affected are Oracle Java SE: 8u361, 8u361-perf, 11.0.18,
    17.0.6, 20; Oracle GraalVM Enterprise Edition: 20.3.9, 21.3.5 and 22.3.1. Difficult to exploit
    vulnerability alLows unauthenticated attacker with network access via HTTPS to compromise Oracle Java SE,
    Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized
    ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Java SE, Oracle GraalVM
    Enterprise Edition. Note: This vulnerability applies to Java deployments, typically in clients running
    sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g.,
    code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also
    be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to
    the APIs. CVSS 3.1 Base Score 5.9 (Availability impacts). CVSS Vector:
    (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H).
      CVE-2023-21954:
      Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE
    (component: Libraries). Supported versions that are affected are Oracle Java SE: 8u361, 8u361-perf,
    11.0.18, 17.0.6, 20; Oracle GraalVM Enterprise Edition: 20.3.9, 21.3.5 and 22.3.1. Difficult to exploit
    vulnerability alLows unauthenticated attacker with network access via multiple protocols to compromise
    Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in
    unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition
    accessible data. Note: This vulnerability applies to Java deployments, typically in clients running
    sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g.,
    code that comes from the internet) and rely on the Java sandbox for security. This vulnerability can also
    be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to
    the APIs. CVSS 3.1 Base Score 3.7 (Integrity impacts). CVSS Vector:
    (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N).
      CVE-2023-21937:
      Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE
    (component: Networking). Supported versions that are affected are Oracle Java SE: 8u361, 8u361-perf,
    11.0.18, 17.0.6, 20; Oracle GraalVM Enterprise Edition: 20.3.9, 21.3.5 and 22.3.1. Difficult to exploit
    vulnerability alLows unauthenticated attacker with network access via multiple protocols to compromise
    Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in

    be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to
    the APIs.
      CVE-2023-21938:
      Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE
    (component: Libraries). Supported versions that are affected are Oracle Java SE: 8u361, 8u361-perf,
    11.0.18, 17.0.6, 20; Oracle GraalVM Enterprise Edition: 20.3.8, 21.3.4 and 22.3.0. Difficult to exploit
    vulnerability alLows unauthenticated attacker with network access via multiple protocols to compromise
    Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in
    unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition
    accessible data. Note: This vulnerability applies to Java deployments, typically in clients running
    sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g.,
    code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not
    apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed
    by an administrator).
      CVE-2023-21939:
      Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE
    (component: Swing). Supported versions that are affected are Oracle Java SE: 8u361, 8u361-perf, 11.0.18,
    17.0.6, 20; Oracle GraalVM Enterprise Edition: 20.3.9, 21.3.5 and 22.3.1. Easily exploitable vulnerability
    alLows unauthenticated attacker with network access via HTTP to compromise Oracle Java SE, Oracle GraalVM
    Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized update, insert or
    delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This
    vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start
    applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the
