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". Si estos elementos se han liberado por la flta de referencias robustas, podría ocurrir un cierre inesperado potencialmente explotable cuando se acceden a los elementos liberados. • http://www.securityfocus.com/bid/100202 http://www.securitytracker.com/id/1039124 https://access.redhat.com/errata/RHSA-2017:2456 https://access.redhat.com/errata/RHSA-2017:2534 https://bugzilla.mozilla.org/show_bug.cgi?id=1378147 https://security.gentoo.org/glsa/201803-14 https://www.debian.org/security/2017/dsa-3928 https://www.debian.org/security/2017/dsa-3968 https://www.mozilla.org/security/advisories/mfsa2017-18 https://www.mozilla.org/security/advisories/mfsa2017-19 • CWE-416: Use After Free •

A use-after-free vulnerability can occur when an editor DOM node is deleted prematurely during tree traversal while still bound to the document. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.

Memory safety bugs were reported in Firefox 54, Firefox ESR 52.2, and Thunderbird 52.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55. Se han reportado errores de seguridad de memoria en Firefox 54, Firefox ESR 52.2, y Thunderbird 52.2.

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-2017-7791
On pages containing an iframe, the "data:" protocol can be used to create a modal alert that will render over arbitrary domains following page navigation, spoofing of the origin of the modal alert from the iframe content. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55. En las páginas que contienen un iframe, el protocolo "data:" se puede emplear para crear una alerta modal que se representará sobre dominios arbitrarios siguiendo la navegación, suplantando el origen de la alerta modal del contenido iframe.
