Descriptions

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: Security). Supported versions that are affected are Java SE: 11.0.3 and 12.0.1. 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. Successful attacks of this vulnerability can result in 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 3.1 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).

Una vulnerabilidad en el componente Java SE de Java SE de Oracle (subcomponente: Security). Las versiones compatibles que están afectadas son Java SE: 11.0.3 y 12.0.1. 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 distinta al atacante. Los ataques con éxito de esta vulnerabilidad pueden resultar en un acceso de lectura no autorizado a un subconjunto de datos accesibles de Java SE. Nota: Esta vulnerabilidad se aplica a las implementaciones Java, normalmente en clientes que ejecutan aplicaciones Java Web Start en sandbox o applets Java en sandbox (en Java SE versión 8), que cargan y ejecutan código no confiable (por ejemplo, código que proviene de Internet) y confían en el sandbox de Java por seguridad. Esta vulnerabilidad no se aplica a las implementaciones Java, normalmente en servidores, que cargan y ejecutan solo código confiable (por ejemplo, código instalado mediante un administrador). CVSS 3.0 Puntuación Base 3.1 (Impactos de confidencialidad). Vector CVSS: (CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:N/A:N).
