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 •
CVE-2018-5143
https://notcve.org/view.php?id=CVE-2018-5143
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') •
CVE-2018-5135
https://notcve.org/view.php?id=CVE-2018-5135
WebExtensions can bypass normal restrictions in some circumstances and use "browser.tabs.executeScript" to inject scripts into contexts where this should not be allowed, such as pages from other WebExtensions or unprivileged "about:" pages. This vulnerability affects Firefox < 59. WebExtensions puede omitir las restricciones normales en algunas circunstancias y utilizar "browser.tabs.executeScript" para inyectar secuencias de comandos en contextos en los que esto no debería permitirse, como páginas de otros WebExtensions o páginas "about:" no privilegiadas. 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=1431371 https://usn.ubuntu.com/3596-1 https://www.mozilla.org/security/advisories/mfsa2018-06 • CWE-862: Missing Authorization •
CVE-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 •
CVE-2018-5125 – Mozilla: Memory safety bugs fixed in Firefox 59 and Firefox ESR 52.7 (MFSA 2018-07)
https://notcve.org/view.php?id=CVE-2018-5125
Memory safety bugs were reported in Firefox 58 and Firefox ESR 52.6. 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 < 52.7, Firefox ESR < 52.7, and Firefox < 59. Se han informado de errores de seguridad de memoria en Firefox 58 y Firefox ESR 52.6. Algunos de estos errores mostraron evidencias de corrupción de memoria y se cree que, con el esfuerzo necesario, se podrían explotar para ejecutar código arbitrario. • 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/buglist.cgi?bug_id=1416529%2C1434580%2C1434384%2C1437450%2C1437507%2C1426988%2C1438425%2C1324042%2C1437087%2C1443865%2C1425520 https://lists.debian.org/debian-lts-announce/2018/03/msg00010.html https: • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
