CVSS: 7.1EPSS: 0%CPEs: 15EXPL: 0CVE-2018-12397 – Mozilla: WebExtension local file permission check bypass
https://notcve.org/view.php?id=CVE-2018-12397
A WebExtension can request access to local files without the warning prompt stating that the extension will "Access your data for all websites" being displayed to the user. This allows extensions to run content scripts in local pages without permission warnings when a local file is opened. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63. WebExtensions pueden solicitar el acceso a archivos locales sin que salte un aviso de advertencia en el que consta que la extensión accederá a sus datos para todo sitio web, mostrándose así al usuario. Esto permite que las extensiones ejecuten scripts de contenido en páginas locales sin advertencias de permisos al abrir un archivo local. • 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=1487478 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-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-862: Missing Authorization •
CVSS: 7.5EPSS: 0%CPEs: 15EXPL: 0CVE-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 •
CVSS: 6.5EPSS: 0%CPEs: 11EXPL: 1CVE-2018-18520 – elfutils: eu-size cannot handle recursive ar files
https://notcve.org/view.php?id=CVE-2018-18520
An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174. Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file. Existe una desreferencia de dirección de memoria inválida en la función elf_end en elfutils hasta la versión v0.174. Aunque se supone que eu-size soporta archivos ar dentro de archivos ar, handle_ar en size.c cierra el archivo ar externo antes de gestionar todas la entradas internas. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00052.html https://access.redhat.com/errata/RHSA-2019:2197 https://lists.debian.org/debian-lts-announce/2019/02/msg00036.html https://lists.debian.org/debian-lts-announce/2021/10/msg00030.html https://sourceware.org/bugzilla/show_bug.cgi?id=23787 https://sourceware.org/ml/elfutils-devel/2018-q4/msg00057.html https://usn.ubuntu.com/4012-1 https://access.redhat.com/security/cve/CVE-2018-18520 https://bugzilla.redh • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2018-18521
Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled. Vulnerabilidades de división entre cero en la función arlib_add_symbols() en arlib.c en elfutils 0.174 permiten que los atacantes remotos provoquen una denegación de servicio (cierre inesperado de la aplicación) con un archivo ELF manipulado, tal y como queda demostrado con eu-ranlib. Esto se debe a que se gestiona de manera incorrecta un sh_entsize con valor cero. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00052.html https://access.redhat.com/errata/RHSA-2019:2197 https://lists.debian.org/debian-lts-announce/2019/02/msg00036.html https://lists.debian.org/debian-lts-announce/2021/10/msg00030.html https://sourceware.org/bugzilla/show_bug.cgi?id=23786 https://sourceware.org/ml/elfutils-devel/2018-q4/msg00055.html https://usn.ubuntu.com/4012-1 https://access.redhat.com/security/cve/CVE-2018-18521 https://bugzilla.redh • CWE-369: Divide By Zero •
