Descriptions

Vulnerability in the Java SE product of Oracle Java SE (component: Javadoc). Supported versions that are affected are Java SE: 7u231, 8u221, 11.0.4 and 13. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, attacks may significantly impact additional products. 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 does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.0 Base Score 4.7 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N).

Una vulnerabilidad en el producto Java SE de Oracle Java SE (componente: Javadoc). Las versiones compatibles que están afectadas son en Java SE: 7u231, 8u221, 11.0.4 y 13. 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. Los ataques con éxito requieren la interacción humana de otra persona diferente del atacante y, aunque la vulnerabilidad se encuentre en Java SE, los ataques pueden impactar significativamente a productos adicionales. Los ataques con éxito de esta vulnerabilidad pueden resultar en actualizar, insertar o eliminar de forma no autorizada el acceso a algunos de los datos accesibles de Java SE, así como también el acceso de lectura no autorizado a un subconjunto de datos accesibles de Java SE. 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 no aplica a las implementaciones de Java, generalmente en servidores, que cargan y ejecutan solo código confiable (por ejemplo, código instalado por un administrador). CVSS 3.0 Puntuación Base 4.7 (Impactos de la Confidencialidad e Integridad). Vector CVSS: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N).

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.
