CVE-2018-12388

https://notcve.org/view.php?id=CVE-2018-12388

Mozilla developers and community members reported memory safety bugs present in Firefox 62. 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 Firefox < 63. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron problemas de seguridad existentes en Firefox 62. Algunos de estos errores mostraban 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/105721 http://www.securitytracker.com/id/1041944 https://bugzilla.mozilla.org/buglist.cgi?bug_id=1472639%2C1485698%2C1301547%2C1471427%2C1379411%2C1482122%2C1486314%2C1487167 https://usn.ubuntu.com/3801-1 https://www.mozilla.org/security/advisories/mfsa2018-26 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2018-12403

If a site is loaded over a HTTPS connection but loads a favicon resource over HTTP, the mixed content warning is not displayed to users. This vulnerability affects Firefox < 63. Si se carga un sitio mediante una conexión HTTPS y, en consecuencia, se carga un recurso favicon mediante HTTP, no salta la advertencia de contenido mixto a los usuarios. Esta vulnerabilidad afecta a las versiones anteriores a la 63 de Firefox. • http://www.securityfocus.com/bid/105721 http://www.securitytracker.com/id/1041944 https://bugzilla.mozilla.org/show_bug.cgi?id=1484753 https://usn.ubuntu.com/3801-1 https://www.mozilla.org/security/advisories/mfsa2018-26 •

CVE-2018-12399

https://notcve.org/view.php?id=CVE-2018-12399

When a new protocol handler is registered, the API accepts a title argument which can be used to mislead users about which domain is registering the new protocol. This may result in the user approving a protocol handler that they otherwise would not have. This vulnerability affects Firefox < 63. Cuando se registra un nuevo manipulador de protocolos, la API acepta un argumento de títulos que puede utilizarse para engañar a los usuarios para que duden sobre el dominio que está registrando el nuevo protocolo. Esto puede provocar que el usuario apruebe un manipulador de protocolo que normalmente no tendría. • http://www.securityfocus.com/bid/105721 http://www.securitytracker.com/id/1041944 https://bugzilla.mozilla.org/show_bug.cgi?id=1490276 https://usn.ubuntu.com/3801-1 https://www.mozilla.org/security/advisories/mfsa2018-26 • CWE-287: Improper Authentication •

CVE-2018-12395 – Mozilla: WebExtension bypass of domain restrictions through header rewriting

https://notcve.org/view.php?id=CVE-2018-12395

By rewriting the Host: request headers using the webRequest API, a WebExtension can bypass domain restrictions through domain fronting. This would allow access to domains that share a host that are otherwise restricted. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63. Al reescribir las cabeceras "Host: request" que utilizan la API webRequest, WebExtensions pueden omitir las restricciones de dominio mediante la fronting del dominio. Esto permitiría el acceso a dominios, cuyo acceso es normalmente restringido, que comparten un host. • http://www.securityfocus.com/bid/105718 http://www.securitytracker.com/id/1041944 https://access.redhat.com/errata/RHSA-2018:3005 https://access.redhat.com/errata/RHSA-2018:3006 https://bugzilla.mozilla.org/show_bug.cgi?id=1467523 https://lists.debian.org/debian-lts-announce/2018/11/msg00008.html https://security.gentoo.org/glsa/201811-04 https://usn.ubuntu.com/3801-1 https://www.debian.org/security/2018/dsa-4324 https://www.mozilla.org/security/advisories/mfsa2018-26&# • CWE-284: Improper Access Control •

CVE-2018-12387 – Mozilla: stack out-of-bounds read in Array.prototype.push

https://notcve.org/view.php?id=CVE-2018-12387

A vulnerability where the JavaScript JIT compiler inlines Array.prototype.push with multiple arguments that results in the stack pointer being off by 8 bytes after a bailout. This leaks a memory address to the calling function which can be used as part of an exploit inside the sandboxed content process. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3. Vulnerabilidad por la cual el compilador JIT de JavaScript inserta Array.prototype.push con múltiples argumentos que resultan en que el puntero de la pila está fuera de su sitio por 8 bytes tras un bailout. Esto filtra una dirección de memoria a la función llamante que puede emplearse como parte de un exploit dentro del proceso de contenido en sandbox. • http://www.securityfocus.com/bid/105460 http://www.securitytracker.com/id/1041770 https://access.redhat.com/errata/RHSA-2018:2881 https://access.redhat.com/errata/RHSA-2018:2884 https://bugzilla.mozilla.org/show_bug.cgi?id=1493903 https://security.gentoo.org/glsa/201810-01 https://usn.ubuntu.com/3778-1 https://www.debian.org/security/2018/dsa-4310 https://www.mozilla.org/security/advisories/mfsa2018-24 https://access.redhat.com/security/cve/CVE-2018-12387 https:/&#x • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •
