https://notcve.org/view.php?id=CVE-2017-7803
When a page's content security policy (CSP) header contains a "sandbox" directive, other directives are ignored. This results in the incorrect enforcement of CSP. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55. Cuando la cabecera CSP (Content Security Policy) de una página contiene una directiva "sandbox", se ignoran otras directivas.

https://notcve.org/view.php?id=CVE-2017-7800
A use-after-free vulnerability can occur in WebSockets when the object holding the connection is freed before the disconnection operation is finished. This results in an exploitable crash. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.

https://notcve.org/view.php?id=CVE-2017-7802
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".
