CVE-2019-11716
https://notcve.org/view.php?id=CVE-2019-11716
Until explicitly accessed by script, window.globalThis is not enumerable and, as a result, is not visible to code such as Object.getOwnPropertyNames(window). Sites that deploy a sandboxing that depends on enumerating and freezing access to the window object may miss this, allowing their sandboxes to be bypassed. This vulnerability affects Firefox < 68. Hasta que se acceda de forma explícita mediante un script, window.globalThis no es enumerable y, como resultado, no es visible para código tal y como Object.getOwnPropertyNames(window). Los sitios que implementan un sandbox que depende de la enumeración y la congelación del acceso al objeto de la ventana pueden pasarlo por alto, lo que permite que se eludan sus sandbox. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1552632 https://security.gentoo.org/glsa/201908-12 https://www.mozilla.org/security/advisories/mfsa2019-21 • CWE-20: Improper Input Validation •
CVE-2019-11711 – Mozilla: Script injection within domain through inner window reuse
https://notcve.org/view.php?id=CVE-2019-11711
When an inner window is reused, it does not consider the use of document.domain for cross-origin protections. If pages on different subdomains ever cooperatively use document.domain, then either page can abuse this to inject script into arbitrary pages on the other subdomain, even those that did not use document.domain to relax their origin security. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8. Cuando se reutiliza una ventana interior, no se considera el uso de document.domain para las protecciones de origen cruzado. Si las páginas en diferentes subdominios alguna vez usan cooperativamente document.domain, entonces cualquiera de las páginas puede abusar de esto para inyectar el script en páginas arbitrarias en el otro subdominio, incluso aquellas que no usaron document.domain para mitigar la seguridad de su origen. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00073.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html https://bugzilla.mozilla.org/show_bug.cgi?id=1552541 https://lists.debian.org/debian-lts-announce/2019/08/msg00001.html https:/ • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •
CVE-2019-11712 – Mozilla: Cross-origin POST requests can be made with NPAPI plugins by following 308 redirects
https://notcve.org/view.php?id=CVE-2019-11712
POST requests made by NPAPI plugins, such as Flash, that receive a status 308 redirect response can bypass CORS requirements. This can allow an attacker to perform Cross-Site Request Forgery (CSRF) attacks. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8. Las peticiones POST realizadas por complementos de NPAPI, tal y como Flash, que reciben una respuesta de redireccionamiento del estado 308 pueden pasar por alto los requerimientos de CORS. Esto puede permitir a un atacante realizar ataques de tipo Cross-Site Request Forgery (CSRF). • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00073.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html https://bugzilla.mozilla.org/show_bug.cgi?id=1543804 https://lists.debian.org/debian-lts-announce/2019/08/msg00001.html https:/ • CWE-352: Cross-Site Request Forgery (CSRF) CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
CVE-2019-11713 – Mozilla: Use-after-free with HTTP/2 cached stream
https://notcve.org/view.php?id=CVE-2019-11713
A use-after-free vulnerability can occur in HTTP/2 when a cached HTTP/2 stream is closed while still in use, resulting in a potentially exploitable crash. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8. Puede ocurrir una vulnerabilidad de uso de la memoria previamente liberada en HTTP/2 cuando una transmisión HTTP/2 almacenada en caché se cierra cuando aún está en uso, lo que resulta en un bloqueo potencialmente explotable. Esta vulnerabilidad afecta a Firefox ESR anterior a versión 60.8, Firefox anterior a versión 68 y Thunderbird anterior a versión 60.8. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00073.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html https://bugzilla.mozilla.org/show_bug.cgi?id=1528481 https://lists.debian.org/debian-lts-announce/2019/08/msg00001.html https:/ • CWE-416: Use After Free •
CVE-2019-11730 – Mozilla: Same-origin policy treats all files in a directory as having the same-origin
https://notcve.org/view.php?id=CVE-2019-11730
A vulnerability exists where if a user opens a locally saved HTML file, this file can use file: URIs to access other files in the same directory or sub-directories if the names are known or guessed. The Fetch API can then be used to read the contents of any files stored in these directories and they may uploaded to a server. It was demonstrated that in combination with a popular Android messaging app, if a malicious HTML attachment is sent to a user and they opened that attachment in Firefox, due to that app's predictable pattern for locally-saved file names, it is possible to read attachments the victim received from other correspondents. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8. Se presenta una vulnerabilidad donde, si un usuario abre un archivo HTML guardado localmente, este archivo puede usar URIs file: para acceder a otros archivos en el mismo directorio o subdirectorios si los nombres son conocidos o adivinados. • https://github.com/alidnf/CVE-2019-11730 http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00073.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html https://bugzilla.mozilla.org/show_bug.cgi?id=1558299 https://lists.debian.org/debian& • CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
