https://notcve.org/view.php?id=CVE-2017-7779
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. Algunos de estos errores mostraron evidencias de corrupción de memoria y se entiende que, con el suficiente esfuerzo, algunos de estos podrían explotarse para ejecutar código arbitrario. • http://www.securityfocus.com/bid/100201 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/buglist.cgi?bug_id=1354443%2C1368576%2C1366903%2C1369913%2C1371424%2C1346590%2C1371890%2C1372985%2C1362924%2C1368105%2C1369994%2C1371283%2C1368362%2C1378826%2C1380426%2C1368030%2C1373220%2C1321384%2C1383002 https://security.gentoo.org/glsa/201803-14 https://www.debian.org/security/2017/dsa-3928 https://www.deb • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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. La vulnerabilidad afecta a Thunderbird en versiones anteriores a la 52.3, Firefox ESR en versiones anteriores a la 52.3 y Firefox en versiones anteriores a la 55. • http://www.securityfocus.com/bid/100240 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=1365875 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-20: Improper Input Validation CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
