Descriptions

Hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an object's address can be discovered through hash codes, and also allows for data leakage of an object's content using these hash codes. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.

Los códigos hasheados de objetos JavaScript se comparten entre páginas. Esto permite fugas de puntero debido a que se puede descubrir la dirección de un objeto por medio de los códigos hash y, además, permite el filtrado de datos del contenido de un objeto mediante estos códigos de hash. La vulnerabilidad afecta a Thunderbird en versiones anteriores a la 45.7, Firefox ESR en versiones anteriores a la 45.7 y Firefox en versiones anteriores a la 51.
