ntpd in NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (ntpd abort) by a large request data value, which triggers the ctl_getitem function to return a NULL value. Ntpd en NTP en versiones anteriores a 4.2.8p7 y 4.3.x en versiones anteriores a 4.3.92 permite a los atacantes remotos causar una denegación de servicio (ntpd abort) por un gran petición de valores de datos, lo que activa la función ctl_getitem para devolver un valor NULL. • http://support.ntp.org/bin/view/Main/NtpBug3008 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/88204 http://www.securitytracker.com/id/1035705 https://security.FreeBSD.org/advisories/FreeBSD-SA-16:16.ntp.asc https://security.gentoo.org/glsa/201607-15 https://security.netapp.com/advisory/ntap-20171004-0002 https://www.kb.cert.org/vuls/id/718152 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.5EPSS: 8%CPEs: 90EXPL: 0CVE-2015-7978 – ntp: stack exhaustion in recursive traversal of restriction list
https://notcve.org/view.php?id=CVE-2015-7978
NTP before 4.2.8p6 and 4.3.0 before 4.3.90 allows a remote attackers to cause a denial of service (stack exhaustion) via an ntpdc relist command, which triggers recursive traversal of the restriction list. NTP en versiones anteriores a 4.2.8p6 y 4.3.0 en versiones anteriores a 4.3.90 permite a atacantes remotos provocar una denegación de servicio (agotamiento de la pila) a través de un comando ntpdc relist, lo que desencadena el recorrido recursivo de la lista de restricciones. A stack-based buffer overflow flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. A remote attacker could use this flaw to crash ntpd. • http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177507.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/176434.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00038.html http://lists.opensuse.org/opensuse-security-announce&# • CWE-121: Stack-based Buffer Overflow CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2015-8158
The getresponse function in ntpq in NTP versions before 4.2.8p9 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (infinite loop) via crafted packets with incorrect values. La función getresponse en ntpq en NTP versiones anteriores a 4.2.8p9 y 4.3.x en versiones anteriores a 4.3.90 permite a los atacantes remotos causar una denegación de servicio (bucle infinito) a través de paquetes creados con valores incorrectos. A flaw was found in the way the ntpq client processed certain incoming packets in a loop in the getresponse() function. A remote attacker could potentially use this flaw to crash an ntpq client instance. • http://rhn.redhat.com/errata/RHSA-2016-2583.html http://support.ntp.org/bin/view/Main/NtpBug2948 http://www.debian.org/security/2016/dsa-3629 http://www.securityfocus.com/bid/81814 http://www.securitytracker.com/id/1034782 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03750en_us https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03766en_us https://security.FreeBSD.org/advisories/FreeBSD-SA-16:09. • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

https://notcve.org/view.php?id=CVE-2015-7979
NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service (client-server association tear down) by sending broadcast packets with invalid authentication to a broadcast client. NTP en versiones anteriores a 4.2.8p6 y 4.3.x en versiones anteriores a 4.3.90 permite a atacantes remotos causar una denegación de servicio (asociación cliente-servidor) por el envío de paquetes de difusión con autenticación no válida a un cliente transmisor. It was found that when NTP was configured in broadcast mode, a remote attacker could broadcast packets with bad authentication to all clients. The clients, upon receiving the malformed packets, would break the association with the broadcast server, causing them to become out of sync over a longer period of time. • http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177507.html http://lists.fedoraproject.org/pipermail/package-announce/2016-January/176434.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00038.html http://lists.opensuse.org/opensuse-security-announce&# • CWE-19: Data Processing Errors CWE-20: Improper Input Validation •
