CVE-2017-14491 – Dnsmasq < 2.78 - 2-byte Heap Overflow
https://notcve.org/view.php?id=CVE-2017-14491
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 DNS response. 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 utilizando una respuesta DNS manipulada. A heap buffer overflow was found in dnsmasq in the code responsible for building DNS replies. An attacker could send crafted DNS packets to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. Dnsmasq versions prior to 2.78 suffer from a 2-byte heap-based overflow vulnerability. • https://www.exploit-db.com/exploits/42941 https://github.com/skyformat99/dnsmasq-2.4.1-fix-CVE-2017-14491 http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00006.html http://nvidia.custhelp.com/app/answers/detail/a_id/4560 http://nvidia.custhelp.com/a • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2016-5285 – nss: Missing NULL check in PK11_SignWithSymKey / ssl3_ComputeRecordMACConstantTime causes server crash
https://notcve.org/view.php?id=CVE-2016-5285
A Null pointer dereference vulnerability exists in Mozilla Network Security Services due to a missing NULL check in PK11_SignWithSymKey / ssl3_ComputeRecordMACConstantTime, which could let a remote malicious user cause a Denial of Service. Existe una vulnerabilidad de desreferencia de puntero nulo en Mozilla Network Security Services debido a una falta de verificación NULL en PK11_SignWithSymKey / ssl3_ComputeRecordMACConstantTime, lo que podría permitir que un usuario malintencionado remoto cause una Denegación de servicio. A NULL pointer dereference flaw was found in the way NSS handled invalid Diffie-Hellman keys. A remote client could use this flaw to crash a TLS/SSL server using NSS. • http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00049.html http://rhn.redhat.com/errata/RHSA-2016-2779.html http://www.securityfocus.com/bid/94349 http://www.ubuntu.com/usn/USN-3163-1 https://bto.bluecoat.com/security-advisory/sa137 https://bugzilla.mozilla.org/show_bug.cgi?id=1306103 https://security.gentoo.org/glsa • CWE-476: NULL Pointer Dereference •
CVE-2016-2776 – ISC BIND 9 - Denial of Service
https://notcve.org/view.php?id=CVE-2016-2776
buffer.c in named in ISC BIND 9 before 9.9.9-P3, 9.10.x before 9.10.4-P3, and 9.11.x before 9.11.0rc3 does not properly construct responses, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted query. buffer.c en named en ISC BIND 9 en versiones anteriores a 9.9.9-P3, 9.10.x en versiones anteriores a 9.10.4-P3 y 9.11.x en versiones anteriores a 9.11.0rc3 no construye respuestas adecuadamente, lo que permite a atacantes remotos provocar una denegación de servicio (fallo de aserción y salida de demonio) a través de una consulta manipulada. A denial of service flaw was found in the way BIND constructed a response to a query that met certain criteria. A remote attacker could use this flaw to make named exit unexpectedly with an assertion failure via a specially crafted DNS request packet. A defect in the rendering of messages into packets can cause named to exit with an assertion failure in buffer.c while constructing a response to a query that meets certain criteria. This assertion can be triggered even if the apparent source address isnt allowed to make queries. • https://www.exploit-db.com/exploits/40453 https://github.com/infobyte/CVE-2016-2776 http://rhn.redhat.com/errata/RHSA-2016-1944.html http://rhn.redhat.com/errata/RHSA-2016-1945.html http://rhn.redhat.com/errata/RHSA-2016-2099.html http://www.oracle.com/technetwork/topics/security/bulletinoct2016-3090566.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.oracle.com/technetwork/topics/security/ovmbulletinoct2016-3090547.html http://www.securityf • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •
CVE-2016-2182 – openssl: Out-of-bounds write caused by unchecked errors in BN_bn2dec()
https://notcve.org/view.php?id=CVE-2016-2182
The BN_bn2dec function in crypto/bn/bn_print.c in OpenSSL before 1.1.0 does not properly validate division results, which allows remote attackers to cause a denial of service (out-of-bounds write and application crash) or possibly have unspecified other impact via unknown vectors. La función BN_bn2dec en crypto/bn/bn_print.c en OpenSSL en versiones anteriores a 1.1.0 no valida adecuadamente resultados de la división, lo que permite a atacantes remotos provocar una denegación de servicio (escritura fuera de límites y caída de la aplicación) o tener otro posible impacto no especificado a través de vectores desconocidos. An out of bounds write flaw was discovered in the OpenSSL BN_bn2dec() function. An attacker able to make an application using OpenSSL to process a large BIGNUM could cause the application to crash or, possibly, execute arbitrary code. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759 http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.h • CWE-391: Unchecked Error Condition CWE-787: Out-of-bounds Write •
