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 •

https://notcve.org/view.php?id=CVE-2018-18559
In the Linux kernel through 4.19, a use-after-free can occur due to a race condition between fanout_add from setsockopt and bind on an AF_PACKET socket. This issue exists because of the 15fe076edea787807a7cdc168df832544b58eba6 incomplete fix for a race condition. The code mishandles a certain multithreaded case involving a packet_do_bind unregister action followed by a packet_notifier register action. Later, packet_release operates on only one of the two applicable linked lists. The attacker can achieve Program Counter control. • https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2019:0163 https://access.redhat.com/errata/RHSA-2019:0188 https://access.redhat.com/errata/RHSA-2019:1170 https://access.redhat.com/errata/RHSA-2019:1190 https://access.redhat.com/errata/RHSA-2019:3967 https://access.redhat.com/errata/RHSA-2019:4159 https://access.redhat.com/errata/RHSA-2020:0174 https://blogs.securiteam.com/index.php/archives/3731 https://access.redhat.com/security/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

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.

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 •
