CVSS: 6.5EPSS: 1%CPEs: 45EXPL: 0CVE-2015-7702 – ntp: incomplete checks in ntp_crypto.c
https://notcve.org/view.php?id=CVE-2015-7702
The crypto_xmit function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash). NOTE: This vulnerability exists due to an incomplete fix for CVE-2014-9750. La función crypto_xmit en ntpd en NTP 4.2.x en versiones anteriores a 4.2.8p4, y 4.3.x en versiones anteriores a 4.3.77 permite que atacantes remotos provoquen una denegación de servicio. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-9750. It was found that the fix for CVE-2014-9750 was incomplete: three issues were found in the value length checks in NTP's ntp_crypto.c, where a packet with particular autokey operations that contained malicious data was not always being completely validated. • http://rhn.redhat.com/errata/RHSA-2016-0780.html http://rhn.redhat.com/errata/RHSA-2016-2583.html http://support.ntp.org/bin/view/Main/NtpBug2899 http://www.debian.org/security/2015/dsa-3388 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/77286 http://www.securitytracker.com/id/1033951 https://security.gentoo.org/glsa/201607-15 https://security.netapp.com/advisory/ntap-20171004-0001 https://access.redhat.com& • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2015-7855
The decodenetnum function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (assertion failure) via a 6 or mode 7 packet containing a long data value. La función decodenetnum en ntpd en NTP 4.2.x en versiones anteriores a 4.2.8p4, y 4.3.x en versiones anteriores a 4.3.77 permite que atacantes remotos provoquen una denegación de servicio (fallo de aserción) empleando un paquete en modo 6 o modo 7 que contiene un valor de datos largo. NTP version 4.2.8p3 suffers from a denial of service vulnerability. • https://www.exploit-db.com/exploits/40840 http://support.ntp.org/bin/view/Main/NtpBug2922 http://www.debian.org/security/2015/dsa-3388 http://www.securityfocus.com/bid/77283 http://www.securitytracker.com/id/1033951 https://bugzilla.redhat.com/show_bug.cgi?id=1274264 https://cert-portal.siemens.com/productcert/pdf/ssa-497656.pdf https://h20566.www2.hpe.com/portal/site/hpsc/public/kb/docDisplay?docId=emr_na-c05270839 https://security.gentoo.org/glsa/201607-15 https:/&# • CWE-20: Improper Input Validation •

The rate limiting feature in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to have unspecified impact via a large number of crafted requests. La funcionalidad de limitación de velocidad en NTP 4.x en versiones anteriores a la 4.2.8p4 y 4.3.x en versiones anteriores a la 4.3.77 permite que atacantes remotos provoquen errores sin especificar empleando un gran número de peticiones manipuladas. • http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00048.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016-06 • CWE-20: Improper Input Validation •
