Descriptions
Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: Networking). Supported versions that are affected are Java SE: 7u231, 8u221, 11.0.4 and 13; Java SE Embedded: 8u221. 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: 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. 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).
Vulnerabilidad en el producto Java SE, Java SE Embedded de Oracle Java SE (componente: Networking). Las versiones compatibles que están afectadas son en Java SE: 7u231, 8u221, 11.0.4 y 13; en Java SE Embedded: 8u221. Una vulnerabilidad difícil de explotar permite a un atacante no autenticado con acceso a la red por medio de múltiples protocolos comprometer a Java SE, Java SE Embedded. Los ataques con éxito de esta vulnerabilidad pueden resultar en una capacidad no autorizada para causar una denegación de servicio parcial (DOS parcial) de Java SE, Java SE Embedded. Nota: Esta vulnerabilidad aplica a las implementaciones de Java, generalmente en clientes que ejecutan aplicaciones de Java Web Start en sandbox o applets de Java en sandbox (en Java SE 8), que cargan y ejecutan código no confiable (por ejemplo, código proveniente del Internet) y dependen del sandbox de Java para la seguridad. Esta vulnerabilidad también puede ser explotada mediante el uso de la API en el componente especificado, por ejemplo, por medio de un servicio web que suministra datos a las API. CVSS 3.0 Puntuación Base 3.7 (Impactos de la Disponibilidad). Vector CVSS: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L).
Jan Jancar, Petr Svenda, and Vladimir Sedlacek discovered that a side- channel vulnerability existed in the ECDSA implementation in OpenJDK. An Attacker could use this to expose sensitive information. It was discovered that the Socket implementation in OpenJDK did not properly restrict the creation of subclasses with a custom Socket implementation. An attacker could use this to specially create a Java class that could possibly bypass Java sandbox restrictions. Various other issues were also addressed.
