Buffer overflow in the password management functionality in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote authenticated users to cause a denial of service (daemon crash) or possibly execute arbitrary code via a crafted key file. Un desbordamiento de búfer en la funcionalidad de gestión de contraseñas en NTP 4.2.x en versiones anteriores a la 4.2.8p4, y 4.3.x en versiones anteriores a la 4.3.77 permite que usuarios remotos autenticados provoquen una denegación de servicio o la posibilidad de ejecutar código arbitrario empleando un archivo de claves manipulado. • http://support.ntp.org/bin/view/Main/NtpBug2921 http://www.securityfocus.com/bid/77277 http://www.securitytracker.com/id/1033951 https://bugzilla.redhat.com/show_bug.cgi?id=1274263 https://security.gentoo.org/glsa/201607-15 https://security.netapp.com/advisory/ntap-20171004-0001 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2015-7691 – ntp: incomplete checks in ntp_crypto.c
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 •
