CVSS: 6.1EPSS: 1%CPEs: 7EXPL: 1CVE-2019-11717 – Mozilla: Caret character improperly escaped in origins
https://notcve.org/view.php?id=CVE-2019-11717
A vulnerability exists where the caret ("^") character is improperly escaped constructing some URIs due to it being used as a separator, allowing for possible spoofing of origin attributes. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8. Se presenta una vulnerabilidad en la que el carácter de intercalación ("^") se escapa inapropiadamente al construir algunos URI debido a que se utiliza como separador, lo que permite la posible suplantación de atributos de origen. Esta vulnerabilidad afecta a Firefox ESR anterior a versión 60.8, Firefox anterior a versión 68 y Thunderbird anterior a versión 60.8. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00073.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html https://bugzilla.mozilla.org/show_bug.cgi?id=1548306 https://lists.debian.org/debian-lts-announce/2019/08/msg00001.html https:/ • CWE-116: Improper Encoding or Escaping of Output CWE-138: Improper Neutralization of Special Elements •
CVSS: 8.3EPSS: 0%CPEs: 7EXPL: 2CVE-2019-9811 – Mozilla Firefox Language Pack XUL Injection Sandbox Escape Vulnerability
https://notcve.org/view.php?id=CVE-2019-9811
As part of a winning Pwn2Own entry, a researcher demonstrated a sandbox escape by installing a malicious language pack and then opening a browser feature that used the compromised translation. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8. Como parte de una entrada Pwn2Own ganadora, un investigador demostró un escape del sandbox mediante la instalación de un paquete de idioma malicioso y luego abriendo una funcionalidad del navegador que usaba la traducción comprometida. Esta vulnerabilidad afecta a Firefox ESR anterior a versión 60.8, Firefox anterior a versión 68 y Thunderbird anterior a versión 60.8. This vulnerability allows remote attackers to escape the sandbox on affected installations of Mozilla Firefox. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00073.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1538007 https://bugzilla.mozilla.org/show_bug.cgi?id=1539598 https://bugzilla.mozil • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-807: Reliance on Untrusted Inputs in a Security Decision •

https://notcve.org/view.php?id=CVE-2017-13704
In dnsmasq before 2.78, if the DNS packet size does not match the expected size, the size parameter in a memset call gets a negative value. As it is an unsigned value, memset ends up writing up to 0xffffffff zero's (0xffffffffffffffff in 64 bit platforms), making dnsmasq crash. En las versiones anteriores a la 2.78 de dnsmasq, si el tamaño del paquete DNS no coincide con el tamaño esperado, el parámetro size en una llamada memset obtiene un valor negativo. Como es un valor sin signo, memset acaba escribiendo hasta 0xffffffff ceros (0xffffffffffffffff en plataformas de 64 bits), haciendo que dnsmasq se cierre de manera inesperada. • http://thekelleys.org.uk/dnsmasq/CHANGELOG http://thekelleys.org.uk/gitweb/?p=dnsmasq.git%3Ba=commit%3Bh=63437ffbb58837b214b4b92cb1c54bc5f3279928 http://www.securityfocus.com/bid/101085 http://www.securityfocus.com/bid/101977 http://www.securitytracker.com/id/1039474 https://access.redhat.com/security/vulnerabilities/3199382 https://cert-portal.siemens.com/productcert/pdf/ssa-689071.pdf https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4TK6DWC53WSU6633EVZL7H4PCWBYHMHK https:& • CWE-20: Improper Input Validation •
CVSS: 9.8EPSS: 92%CPEs: 12EXPL: 1CVE-2017-14492 – Dnsmasq < 2.78 - Heap Overflow
https://notcve.org/view.php?id=CVE-2017-14492
Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted IPv6 router advertisement request. Un desbordamiento de búfer basado en memoria dinámica (heap) en dnsmasq en versiones anteriores a la 2.78 permite a los atacantes provocar una denegación de servicio (cierre inesperado) o ejecutar código arbitrario mediante una petición manipulada de anuncio de router IPv6. A heap buffer overflow was discovered in dnsmasq in the IPv6 router advertisement (RA) handling code. An attacker on the local network segment could send crafted RAs to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. This issue only affected configurations using one of these options: enable-ra, ra-only, slaac, ra-names, ra-advrouter, or ra-stateless. • https://www.exploit-db.com/exploits/42942 http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00006.html http://nvidia.custhelp.com/app/answers/detail/a_id/4561 http://thekelleys.org.uk/dnsmasq/CHANGELOG http://thekelleys.org.uk/gitweb/?p=dnsmasq.git%3Ba=commit%3Bh=24036ea507862c7b7898b68289c8130f85599c10 http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2017-005.txt http://www.debian.org/security/2017/dsa-3989 http://www.securityfocus.com/bid/101085 http://www.securitytrac • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2017-14494
dnsmasq before 2.78, when configured as a relay, allows remote attackers to obtain sensitive memory information via vectors involving handling DHCPv6 forwarded requests. Las versiones anteriores a la 2.78 de dnsmasq, cuando se configuran como retransmisor, permiten que los atacantes remotos obtengan información sensible de la memoria mediante vectores relacionados con la gestión de peticiones DHCPv6 reenviadas. An information leak was found in dnsmasq in the DHCPv6 relay code. An attacker on the local network could send crafted DHCPv6 packets to dnsmasq causing it to forward the contents of process memory, potentially leaking sensitive data. Dnsmasq versions prior to 2.78 suffer from an information leak vulnerability. • https://www.exploit-db.com/exploits/42944 http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00006.html http://nvidia.custhelp.com/app/answers/detail/a_id/4561 http://thekelleys.org.uk/dnsmasq/CHANGELOG http://thekelleys.org.uk/gitweb/?p=dnsmasq.git%3Ba=commit%3Bh=33e3f1029c9ec6c63e430ff51063a6301d4b2262 http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2017-005.txt http://www.debian.org/security/2017/dsa-3989 http://www.securityfocus.com/bid/101085 http://www.securitytrac • CWE-125: Out-of-bounds Read CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
