Crypto-NAK packets in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to bypass authentication. Los paquetes Crypto-NAK 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 permiten que atacantes remotos eludan la autenticación. • http://support.ntp.org/bin/view/Main/NtpBug2941 http://www.debian.org/security/2015/dsa-3388 http://www.securityfocus.com/bid/77287 http://www.securitytracker.com/id/1033951 https://bugzilla.redhat.com/show_bug.cgi?id=1274265 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/201604-03 https://security.gentoo.org/glsa/201607-15 https:/& • CWE-287: Improper Authentication •
CVSS: 7.5EPSS: 6%CPEs: 45EXPL: 0CVE-2015-7701 – ntp: slow memory leak in CRYPTO_ASSOC
https://notcve.org/view.php?id=CVE-2015-7701
Memory leak in the CRYPTO_ASSOC 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 (memory consumption). Una fuga de memoria en la función CRYPTO_ASSOC 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 (consumo de memoria). A memory leak flaw was found in ntpd's CRYPTO_ASSOC. If ntpd was configured to use autokey authentication, an attacker could send packets to ntpd that would, after several days of ongoing attack, cause it to run out of memory. • 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/NtpBug2909 http://www.debian.org/security/2015/dsa-3388 http://www.oracle.com/technetwork/topics/security/linuxbulletinapr2016-2952096.html http://www.securityfocus.com/bid/77281 http://www.securitytracker.com/id/1033951 https://bugzilla.redhat.com/show_bug.cgi?id=1274255 https://security.gentoo.org/glsa/201607-15 https://security.netapp.com • CWE-401: Missing Release of Memory after Effective Lifetime CWE-772: Missing Release of Resource after Effective Lifetime •
CVSS: 7.5EPSS: 81%CPEs: 58EXPL: 0CVE-2015-7704 – ntp: disabling synchronization via crafted KoD packet
https://notcve.org/view.php?id=CVE-2015-7704
The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages. El cliente ntpd en NTP 4.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 empleando una serie de mensajes "KOD" manipulados. It was discovered that ntpd as a client did not correctly check timestamps in Kiss-of-Death packets. A remote attacker could use this flaw to send a crafted Kiss-of-Death packet to an ntpd client that would increase the client's polling interval value, and effectively disable synchronization with the server. • http://bugs.ntp.org/show_bug.cgi?id=2901 http://rhn.redhat.com/errata/RHSA-2015-1930.html http://rhn.redhat.com/errata/RHSA-2015-2520.html http://support.ntp.org/bin/view/Main/NtpBug2901 http://support.ntp.org/bin/view/Main/SecurityNotice#October_2015_NTP_4_2_8p4_Securit http://www.debian.org/security/2015/dsa-3388 http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html http://www.securityfocus.com/bid/77280 http://www.securitytracker.com/id/1 • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2015-7691
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) via crafted packets containing particular autokey operations. 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 empleando paquetes manipulados que contengan operaciones de autoclave específicas. 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/77274 http://www.securitytracker.com/id/1033951 https://bugzilla.redhat.com/show_bug.cgi?id=1274254 https://security.gentoo.org/glsa/201607-15 https://security.netapp.com • CWE-20: Improper Input Validation •
