CVSS: 7.8EPSS: 89%CPEs: 12EXPL: 1CVE-2017-14495 – Dnsmasq < 2.78 - Lack of free() Denial of Service
https://notcve.org/view.php?id=CVE-2017-14495
Memory leak in dnsmasq before 2.78, when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service (memory consumption) via vectors involving DNS response creation. Una fuga de memoria en las versiones anteriores a la 2.78 de dnsmasq, cuando están especificadas las opciones --add-mac, --add-cpe-id o --add-subnet, permite que los atacantes remotos provoquen una denegación de servicio (consumo de memoria) mediante vectores relacionados con la creación de respuestas DNS. A memory exhaustion flaw was found in dnsmasq in the EDNS0 code. An attacker could send crafted DNS packets which would trigger memory allocations which would never be freed, leading to unbounded memory consumption and eventually a crash. This issue only affected configurations using one of the options: add-mac, add-cpe-id, or add-subnet. • https://www.exploit-db.com/exploits/42945 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=51eadb692a5123b9838e5a68ecace3ac579a3a45 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.securityfocu • CWE-400: Uncontrolled Resource Consumption CWE-772: Missing Release of Resource after Effective Lifetime •

Integer underflow in the add_pseudoheader function in dnsmasq before 2.78 , when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service via a crafted DNS request. Un desbordamiento inferior de enteros en las versiones anteriores a la 2.78 de dnsmasq, cuando están especificadas las opciones --add-mac, --add-cpe-id o --add-subnet, permite que los atacantes remotos provoquen una denegación de servicio mediante una petición DNS manipulada.

https://notcve.org/view.php?id=CVE-2017-8932
A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by submitting crafted points and observing failures to the derive correct output. This leads to a full key recovery attack against static ECDH, as used in popular JWT libraries. Un error en la implementación de la biblioteca estándar ScalarMult de curve P-256 para arquitecturas amd64 en Go anterior a versión 1.7.6 y 1.8.x anterior a versión 1.8.2, causa resultados incorrectos para ser generados por puntos de entrada específicos. Se puede montar un ataque adaptativo para extraer progresivamente la entrada scalar hacia ScalarMult mediante el envío de puntos creados y observando fallos para la salida correcta derivada. • http://lists.opensuse.org/opensuse-updates/2017-06/msg00079.html http://lists.opensuse.org/opensuse-updates/2017-06/msg00080.html https://access.redhat.com/errata/RHSA-2017:1859 https://bugzilla.redhat.com/show_bug.cgi?id=1455191 https://github.com/golang/go/commit/9294fa2749ffee7edbbb817a0ef9fe633136fa9c https://github.com/golang/go/issues/20040 https://go-review.googlesource.com/c/41070 https://groups.google.com/d/msg/golang-announce/B5ww0iFt1_Q/TgUFJV14BgAJ https://lists.fedoraproject.org&# • CWE-682: Incorrect Calculation •

https://notcve.org/view.php?id=CVE-2017-1000366
glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier. Glibc contiene una vulnerabilidad que permite que los valores LD_LIBRARY_PATH especialmente creados para manipular la región heap/stack de la memoria, generando entonces un alias, lo que podría conllevar a la ejecución del código arbitrario. Tenga en cuenta que se han realizado cambios de refuerzo adicionales en glibc para evitar la manipulación del stack y heap de la memoria de almacenamiento dinámico, pero estos problemas no se pueden explotar directamente, por lo que no se les ha otorgado un CVE. • https://www.exploit-db.com/exploits/42276 https://www.exploit-db.com/exploits/42274 https://www.exploit-db.com/exploits/42275 http://packetstormsecurity.com/files/154361/Cisco-Device-Hardcoded-Credentials-GNU-glibc-BusyBox.html http://seclists.org/fulldisclosure/2019/Sep/7 http://www.debian.org/security/2017/dsa-3887 http://www.securityfocus.com/bid/99127 http://www.securitytracker.com/id/1038712 https://access.redhat.com/errata/RHSA-2017:1479 https://access.redhat.com/errata/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
