Descriptions

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 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 5.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).

Una vulnerabilidad en el producto Java SE, Oracle GraalVM Enterprise Edition de Oracle Java SE (componente: Swing). Las versiones compatibles que están afectadas son Java SE: 7u311, 8u301, 11.0.12, 17; Oracle GraalVM Enterprise Edition: 20.3.3 y 21.2.0. La vulnerabilidad fácilmente explotable permite a un atacante no autenticado con acceso a la red por medio de múltiples protocolos comprometer Java SE, Oracle GraalVM Enterprise Edition. Los ataques con éxito de esta vulnerabilidad pueden resultar en una capacidad no autorizada de causar una negación parcial de servicio (DOS parcial) de Java SE, Oracle GraalVM Enterprise Edition. Nota: Esta vulnerabilidad se aplica a las implantaciones de Java, normalmente en clientes que ejecutan aplicaciones Java Web Start con sandbox o applets Java con sandbox, que cargan y ejecutan código que no es confiable (por ejemplo, código que viene de Internet) y dependen de la sandbox de Java para la seguridad. Esta vulnerabilidad también puede ser explotada al usar APIs en el Componente especificado, por ejemplo, mediante un servicio web que suministra datos a las APIs. CVSS 3.1 Puntuación Base 5.3 (impactos en la Disponibilidad). Vector CVSS: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
