      "value": "A use-after-free vulnerability can occur when the SMIL animation controller incorrectly registers with the refresh driver twice when only a single registration is expected. When a registration is later freed with the removal of the animation controller element, the refresh driver incorrectly leaves a dangling pointer to the driver's observer array. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66."

      "value": "Una vulnerabilidad de uso despu\u00e9s de liberaci\u00f3n de memoria puede darse cuando el controlador de animaci\u00f3n SMIL registra incorrectamente con el controlador de actualizaci\u00f3n dos veces cuando s\u00f3lo se espera un \u00fanico registro. Cuando se libera un registro con la eliminaci\u00f3n del elemento de controlador de animaci\u00f3n, el controlador de actualizaci\u00f3n deja incorrectamente un puntero pendiente en la matriz de observadores del controlador. Esta vulnerabilidad afecta a Thunderbird, versiones anteriores a 60.6, Firefox ESR, versiones anteriores a 60.6 y Firefox. versiones anteriores a 66."
