ALMALINUX9.2:CLSA-2026:1785501342 advisory.

  - Vulnerability in the Java SE product of Oracle Java SE (component: JSSE). Supported versions that are
    affected are Java SE: 11.0.5 and 13.0.1. Difficult to exploit vulnerability allows unauthenticated
    attacker with network access via HTTPS to compromise Java SE. Successful attacks of this vulnerability can
    result in unauthorized update, insert or delete access to some of Java SE accessible data as well as
    unauthorized read access to a subset of Java SE accessible data. Note: This vulnerability applies to Java
    deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets
    (in Java SE 8), 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. (CVE-2020-2655)

  - Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component:
    JSSE). Supported versions that are affected are Java SE: 7u311, 8u301, 11.0.12; Oracle GraalVM Enterprise
    Edition: 20.3.3 and 21.2.0. Difficult to exploit vulnerability allows unauthenticated attacker with
    network access via TLS to compromise Java SE, Oracle GraalVM Enterprise Edition. Successful attacks of
    this vulnerability can result in unauthorized access to critical data or complete access to all 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. (CVE-2021-35550)

  - Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component:
    Swing). Supported versions that are affected are Java SE: 7u311, 8u301, 11.0.12, 17; Oracle GraalVM
    Enterprise Edition: 20.3.3 and 21.2.0. Easily exploitable vulnerability allows unauthenticated attacker
    with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise Edition.
    Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of
    service (partial DOS) of 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 does not apply to Java deployments, typically in servers, that
    load and run only trusted code (e.g., code installed by an administrator). (CVE-2021-35556)

  - Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component:
    Swing). Supported versions that are affected are Java SE: 7u311, 8u301, 11.0.12, 17; Oracle GraalVM
    Enterprise Edition: 20.3.3 and 21.2.0. Easily exploitable vulnerability allows unauthenticated attacker
    with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise Edition.
    Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of

    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. (CVE-2021-35559)

  - Vulnerability in the Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component:
    Utility). Supported versions that are affected are Java SE: 7u311, 8u301, 11.0.12, 17; Oracle GraalVM
    Enterprise Edition: 20.3.3 and 21.2.0. Easily exploitable vulnerability allows unauthenticated attacker
    with network access via multiple protocols to compromise Java SE, Oracle GraalVM Enterprise Edition.
    Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of

    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. (CVE-2021-35561)
