CVSS: 10.0EPSS: 30%CPEs: 54EXPL: 3CVE-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 •

Xen PV guest before Xen 4.3 checked access permissions to MMIO ranges only after accessing them, allowing host PCI device space memory reads, leading to information disclosure. This is an error in the get_user function. NOTE: the upstream Xen Project considers versions before 4.5.x to be EOL. Xen PV guest anterior a Xen 4.3 chequea los permisos de acceso a los rangos MMIO sólo después de acceder a ellos, lo que permite leer en un dispositivo de memoria PCI, dando lugar a la divulgación de información. Se trata de un error en la función get_user. • http://lists.opensuse.org/opensuse-security-announce/2017-05/msg00005.html http://www.securityfocus.com/bid/98314 https://bugzilla.suse.com/show_bug.cgi?id=1033948 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 7.5EPSS: 2%CPEs: 104EXPL: 0CVE-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&#x • CWE-476: NULL Pointer Dereference •

ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (ephemeral-association demobilization) by sending a spoofed crypto-NAK packet with incorrect authentication data at a certain time. ntpd en NTP 4.x en versiones anteriores a 4.2.8p8 permite a atacantes remotos provocar una denegación de servicio (desmovilización de asociación efímera) mediante el envío de un paquete crypto-NAK falsificado con datos de autenticación incorrectos en un momento determinado. • http://bugs.ntp.org/3045 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00040.html http://lists.opensuse.org/ • CWE-287: Improper Authentication •

The process_packet function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service (peer-variable modification) by sending spoofed packets from many source IP addresses in a certain scenario, as demonstrated by triggering an incorrect leap indication. La función process_packet en ntp_proto.c en ntpd en NTP 4.x en versiones anteriores a 4.2.8p8 permite a atacantes remotos provocar una denegación de servicio (modificación de par variable) enviando paquetes falsificados desde muchas direcciones IP de origen en un determinado escenario, según lo demostrado desencadenando una indicación de salto incorrecta. • http://bugs.ntp.org/3044 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00040.html http://lists.opensuse.org/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
