Descriptions

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: 11.0.17, 17.0.5, 19.0.1; Oracle GraalVM Enterprise Edition: 20.3.8, 21.3.4 and 22.3.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via DTLS to compromise Oracle 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 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 does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 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).

Vulnerabilidad en el producto Oracle Java SE, Oracle GraalVM Enterprise Edition de Oracle Java SE (componente: JSSE). Las versiones compatibles que se ven afectadas son Oracle Java SE: 11.0.17, 17.0.5, 19.0.1; Oracle GraalVM Enterprise Edition: 20.3.8, 21.3.4 y 22.3.0. Una vulnerabilidad fácilmente explotable permite que un atacante no autenticado con acceso a la red a través de DTLS comprometa Oracle Java SE, Oracle GraalVM Enterprise Edition. Los ataques exitosos de esta vulnerabilidad pueden resultar en una capacidad no autorizada para causar una denegación de servicio parcial (DOS parcial) de Oracle Java SE, Oracle GraalVM Enterprise Edition. Nota: Esta vulnerabilidad se aplica a implementaciones de Java, generalmente en clientes que ejecutan aplicaciones Java Web Start en espacio aislado o subprogramas de Java en espacio aislado, que cargan y ejecutan código que no es de confianza (por ejemplo, código que proviene de Internet) y dependen del entorno limitado de Java para su seguridad. Esta vulnerabilidad no se aplica a implementaciones de Java, normalmente en servidores, que cargan y ejecutan sólo código confiable (por ejemplo, código instalado por un administrador). 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).
