Descriptions

Vulnerability in the Java SE component of Oracle Java SE (subcomponent: 2D). Supported versions that are affected are Java SE: 7u211 and 8u202. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks of this vulnerability can result in takeover of Java SE. 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 8.1 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).

Se presente una vulnerabilidad en el componente Java SE de Oracle Java SE (subcomponente: 2D). Las versiones compatibles que se ven afectadas son Java SE: versión 7u211 y versión 8u202. Una vulnerabilidad difícil de explotar permite que un atacante no autenticado con acceso a la red por medio de múltiples protocolos comprometa a Java SE. Los ataques con éxito de esta vulnerabilidad pueden conllevar a la adquisición de Java SE. Nota: esta vulnerabilidad se aplica a las implementaciones de Java, generalmente en clientes que ejecutan aplicaciones en espacio aislado (sandboxed) Java Web Start o en applets de Java (en Java SE 8), que cargan y ejecutan código no confiable (por ejemplo, código que proviene de Internet) y se basan en Java sandbox para seguridad. Esta vulnerabilidad no se aplica a las implementaciones de Java, normalmente en servidores, que cargan y ejecutan solo código de confianza (por ejemplo, código instalado por un administrador). CVSS versión 3.0 Base Score versión 8.1 (Impactos de confidencialidad, integridad y disponibilidad). Vector CVSS: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H).

A heap corruption was observed in Oracle Java Runtime Environment version 8u202 (latest at the time of this writing) while fuzz-testing the processing of TrueType, implemented in a proprietary t2k library.
