Descriptions

XStream is a Java library to serialize objects to XML and back again. In XStream before version 1.4.16, there is a vulnerability which may allow a remote attacker to occupy a thread that consumes maximum CPU time and will never return. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.16.

XStream es una biblioteca de Java para serializar objetos a XML y viceversa. En XStream anterior a la versión 1.4.16, se presenta una vulnerabilidad que puede permitir que un atacante remoto ocupe un hilo que consume el máximo tiempo de CPU y nunca regresará. Ningún usuario está afectado, si siguió la recomendación de configurar el framework de seguridad de XStream con una lista blanca limitada a los tipos mínimos requeridos. Si confía en la lista negra predeterminada de XStream del Framework de Seguridad, tendrá que usar al menos la versión 1.4.16
