CVSS: 8.6EPSS: 0%CPEs: 18EXPL: 0CVE-2018-5129 – Mozilla: Out-of-bounds write with malformed IPC messages (MFSA 2018-07)
https://notcve.org/view.php?id=CVE-2018-5129
A lack of parameter validation on IPC messages results in a potential out-of-bounds write through malformed IPC messages. This can potentially allow for sandbox escape through memory corruption in the parent process. This vulnerability affects Thunderbird < 52.7, Firefox ESR < 52.7, and Firefox < 59. La falta de validación de parámetros en los mensajes IPC resulta en una potencial escritura fuera de límites a través de mensajes IPC mal formados. Esto puede permitir un escape de sandbox mediante la corrupción de memoria en el proceso padre. • http://www.securityfocus.com/bid/103388 http://www.securitytracker.com/id/1040514 https://access.redhat.com/errata/RHSA-2018:0526 https://access.redhat.com/errata/RHSA-2018:0527 https://access.redhat.com/errata/RHSA-2018:0647 https://access.redhat.com/errata/RHSA-2018:0648 https://bugzilla.mozilla.org/show_bug.cgi?id=1428947 https://lists.debian.org/debian-lts-announce/2018/03/msg00010.html https://lists.debian.org/debian-lts-announce/2018/03/msg00029.html https://securi • CWE-787: Out-of-bounds Write •

A shared worker created from a "data:" URL in one tab can be shared by another tab with a different origin, bypassing the same-origin policy. This vulnerability affects Firefox < 59. Un worker compartido creado a partir de una URL "data:" en una pestaña puede ser compartido por otra pestaña con un origen diferente, evitando la política de mismo origen. Esta vulnerabilidad afecta a las versiones anteriores a la 59 de Firefox. • http://www.securityfocus.com/bid/103386 http://www.securitytracker.com/id/1040514 https://bugzilla.mozilla.org/show_bug.cgi?id=1419166 https://usn.ubuntu.com/3596-1 https://www.mozilla.org/security/advisories/mfsa2018-06 • CWE-20: Improper Input Validation •
CVSS: 6.1EPSS: 0%CPEs: 17EXPL: 0CVE-2018-5131 – Mozilla: Fetch API improperly returns cached copies of no-store/no-cache resources (MFSA 2018-07)
https://notcve.org/view.php?id=CVE-2018-5131
Under certain circumstances the "fetch()" API can return transient local copies of resources that were sent with a "no-store" or "no-cache" cache header instead of downloading a copy from the network as it should. This can result in previously stored, locally cached data of a website being accessible to users if they share a common profile while browsing. This vulnerability affects Firefox ESR < 52.7 and Firefox < 59. Bajo ciertas circunstancias, la API "fetch()" puede devolver copias locales transitorias de recursos que se enviaron con una cabecera de caché "no-store" o "no-cache" en lugar de descargar una copia de la red, que es lo recomendado. Esto puede dar lugar a que los usuarios puedan acceder a los datos almacenados previamente y almacenados en la caché local de un sitio web si comparten un perfil común durante la navegación. • http://www.securityfocus.com/bid/103388 http://www.securitytracker.com/id/1040514 https://access.redhat.com/errata/RHSA-2018:0526 https://access.redhat.com/errata/RHSA-2018:0527 https://bugzilla.mozilla.org/show_bug.cgi?id=1440775 https://lists.debian.org/debian-lts-announce/2018/03/msg00010.html https://security.gentoo.org/glsa/201810-01 https://usn.ubuntu.com/3596-1 https://www.debian.org/security/2018/dsa-4139 https://www.mozilla.org/security/advisories/mfsa2018-06&# • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •

WebExtensions may use "view-source:" URLs to view local "file:" URL content, as well as content stored in "about:cache", bypassing restrictions that only allow WebExtensions to view specific content. This vulnerability affects Firefox < 59. WebExtensions puede usar URL "view-source:" para visualizar contenido de URL"file:" local, así como el contenido almacenado en "about:cache", omitiendo las restricciones que solo permiten a WebExtensions visualizar contenido específico. Esta vulnerabilidad afecta a las versiones anteriores a la 59 de Firefox. • http://www.securityfocus.com/bid/103386 http://www.securitytracker.com/id/1040514 https://bugzilla.mozilla.org/show_bug.cgi?id=1429379 https://usn.ubuntu.com/3596-1 https://www.mozilla.org/security/advisories/mfsa2018-06 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

URLs using "javascript:" have the protocol removed when pasted into the addressbar to protect users from cross-site scripting (XSS) attacks, but if a tab character is embedded in the "javascript:" URL the protocol is not removed and the script will execute. This could allow users to be socially engineered to run an XSS attack against themselves. This vulnerability affects Firefox < 59. Las URL que utilizan "javascript:" eliminan el protocolo cuando se pega en la barra de direcciones para proteger a los usuarios de ataques Cross-Site Scripting (XSS), pero si hay un carácter de tabulación incrustado en la URL "javascript:", el protocolo no se elimina y el script se ejecutará. Esto podría permitir que se realice ingeniería social sobre los usuarios para ejecutar un ataque Cross-Site Scripting (XSS) contra ellos mismos. • http://www.securityfocus.com/bid/103386 http://www.securitytracker.com/id/1040514 https://bugzilla.mozilla.org/show_bug.cgi?id=1422643 https://usn.ubuntu.com/3596-1 https://www.mozilla.org/security/advisories/mfsa2018-06 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
