ALMALINUX9.2:CLSA-2026:1777645704 advisory.

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Libraries). Supported
    versions that are affected are Java SE: 8u251, 11.0.7 and 14.0.1; Java SE Embedded: 8u251. 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: 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. (CVE-2020-14556)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: JSSE). Supported
    versions that are affected are Java SE: 7u261, 8u251, 11.0.7 and 14.0.1; Java SE Embedded: 8u251.
    Difficult to exploit vulnerability allows unauthenticated attacker with network access via TLS to
    compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized
    read access to a subset of Java SE, Java SE Embedded accessible data. 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. (CVE-2020-14577)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Libraries). Supported
    versions that are affected are Java SE: 7u261 and 8u251; Java SE Embedded: 8u251. 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. (CVE-2020-14578, CVE-2020-14579)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: 2D). Supported
    versions that are affected are Java SE: 8u251, 11.0.7 and 14.0.1; Java SE Embedded: 8u251. 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
    read access to a subset of Java SE, Java SE Embedded accessible data. 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. (CVE-2020-14581)

  - Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Libraries). Supported
    versions that are affected are Java SE: 7u261, 8u251, 11.0.7 and 14.0.1; Java SE Embedded: 8u251.
    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). (CVE-2020-14583)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
