The developer page about:memory has a Measure function for exploring what object types the browser has allocated and their sizes. When this function was invoked we incorrectly called the sizeof function, instead of using the API method that checks for invalid pointers. This vulnerability affects Firefox < 86.
La página del desarrollador about:memory presenta una función Measure para explorar qué tipos de objetos ha asignado el navegador y sus tamaños. Cuando esta función era invocada, llamamos incorrectamente a la función sizeof, en lugar de usar el método API que comprueba punteros no válidos. Esta vulnerabilidad afecta a Firefox versiones anteriores a 86
Multiple vulnerabilities have been found in Mozilla Firefox, the worst of which could result in the arbitrary execution of code. Versions less than 88.0 are affected.
