Descriptions

Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: JAXP). Supported versions that are affected are Java SE: 6u141, 7u131 and 8u121; Java SE Embedded: 8u121; JRockit: R28.3.13. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Java SE, Java SE Embedded, JRockit. Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. CVSS 3.0 Base Score 5.9 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H).

Vulnerabilidad en el componente Java SE, Java SE Embedded, JRockit de Oracle Java SE (subcomponente: JAXP). Versiones compatibles que son afectadas son Java SE: 6u141, 7u131 y 8u121; Java SE Embedded: 8u121; JRockit: R28.3.13. Vulnerabilidad dificil de explotar permite autenticado atacante con acceso a la red a través de múltiples protocolos para comprometer Java SE, Java SE Embedded, JRockit. Los ataques exitosos de esta vulnerabilidad pueden resultar en una habilidad no autorizada para causar un bloqueo o un bloqueo repetible con frecuencia (DOS completo) de Java SE, Java SE Embedded, JRockit. Nota: Se aplica a la implementación de cliente y servidor de Java. Esta vulnerabilidad puede ser explotada a través de aplicaciones de Java Web Start y de Java. También se puede explotar mediante el suministro de datos a las API en el Componente especificado sin utilizar aplicaciones de Java Web Start en modo recinto de seguridad o complementos de Java protegidos, como a través de un servicio web.. CVSS 3.0 Base Score 5.9 (Impactos de disponibilidad). Vector CVSS: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H).

It was found that the JAXP component of OpenJDK failed to correctly enforce parse tree size limits when parsing XML document. An attacker able to make a Java application parse a specially crafted XML document could use this flaw to make it consume an excessive amount of CPU and memory.
