Descriptions
Oracle Java SE before 7 Update 6, and OpenJDK 7 before 7u6 build 12 and 8 before build 39, computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.
Oracle Java SE anteriores a 7 Update 6, y OpenJDK 7 anteriores a 7u6 build 12 y 8 anteriores a build 39, calculan los valores de hash sin restringir la posibilidad de provocar colisiones hash previsibles, lo que permite a atacantes dependientes de contexto provocar una denegación de servicio (consumo de CPU) a través de la manipulación de una entrada para la aplicación que mantiene la tabla de valores hash.
