"The remote NewStart CGSL host, running version MAIN 4.05, has java-1.8.0-openjdk packages installed that are affected by
multiple vulnerabilities:

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Scripting). Supported
    versions that are affected are Java SE: 8u241, 11.0.6 and 14; Java SE Embedded: 8u241. Difficult to
    exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to
    compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized
    ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note: Applies to
    client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start
    applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the
    specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as
    through a web service. CVSS 3.0 Base Score 3.7 (Availability impacts). CVSS Vector:
    (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L). (CVE-2020-2754, CVE-2020-2755)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Serialization).
    Supported versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded: 8u241.
    Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple
    protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in
    unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded.

    sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying
    data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed
    Java applets, such as through a web service. CVSS 3.0 Base Score 3.7 (Availability impacts). CVSS Vector:
    (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L). (CVE-2020-2756, CVE-2020-2757)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Security). Supported
    versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded: 8u241. Difficult to

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Lightweight HTTP
    Server). Supported versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded:
    8u241. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple
    protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in
    unauthorized update, insert or delete access to some of Java SE, Java SE Embedded accessible data as well
    as unauthorized read access to a subset of Java SE, Java SE Embedded accessible data. Note: This
    vulnerability can only be exploited by supplying data to APIs in the specified Component without using
    Untrusted Java Web Start applications or Untrusted Java applets, such as through a web service. CVSS 3.0
    Base Score 4.8 (Confidentiality and Integrity impacts). CVSS Vector:
    (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N). (CVE-2020-2800)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Concurrency).
    Supported versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded: 8u241.
    Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple
    protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in
    unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded.
    Note: Applies to client and server deployment of Java. This vulnerability can be exploited through
    sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying
    data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed
    Java applets, such as through a web service. CVSS 3.0 Base Score 5.3 (Availability impacts). CVSS Vector:
    (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). (CVE-2020-2830)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Libraries). Supported
    versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded: 8u241. Difficult to
    exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to
    compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other
    than the attacker and while the vulnerability is in Java SE, Java SE Embedded, attacks may significantly
    impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE,
    Java SE Embedded. 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). CVSS 3.0 Base Score 8.3 (Confidentiality, Integrity and Availability impacts). CVSS
    Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H). (CVE-2020-2803, CVE-2020-2805)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: JSSE). Supported
    versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded: 8u241. Easily
    exploitable vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Java
    SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized ability to cause
    a partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note: Applies to client and server
    deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and
    sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component
    without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web
    service. CVSS 3.0 Base Score 5.3 (Availability impacts). CVSS Vector:
    (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). (CVE-2020-2781)
