Descriptions
A use-after-free vulnerability can occur when manipulating the DOM during the resize event of an image element. If these elements have been freed due to a lack of strong references, a potentially exploitable crash may occur when the freed elements are accessed. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.
Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada cuando se manipula el DOM durante el evento de redimensionamiento de un elemento "image".

Esta vulnerabilidad afecta a las versiones anteriores a la 52.3 de Thunderbird, las versiones anteriores a la 52.3 de Firefox ESR y las versiones anteriores a la 55 de Firefox.
