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 •

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') •

ntpd in NTP 4.x before 4.2.8p8, when autokey is enabled, allows remote attackers to cause a denial of service (peer-variable clearing and association outage) by sending (1) a spoofed crypto-NAK packet or (2) a packet with an incorrect MAC value at a certain time. ntpd en NTP 4.x en versiones anteriores a 4.2.8p8, cuando está habilitada la autoclave, permite a atacantes remotos provocar una denegación de servicio (limpiando el par variable y corte de asociación) enviando (1) un paquete crypto-NAK manipulado o (2) un paquete con un valor MAC incorrecto en un momento determinado. • http://bugs.ntp.org/3043 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') •

ntpd in NTP before 4.2.8p8 allows remote attackers to cause a denial of service (daemon crash) via a crypto-NAK packet. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-1547. ntpd en NTP en versiones anteriores a 4.2.8p8 permite a atacantes remotos provocar una denegación de servicio (caída del demonio) a través de un paquete crypto-NAK. NOTA: esta vulnerabilidad existe debido a una solución incorrecta para CVE-2016-1547. • http://bugs.ntp.org/3046 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00018.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://support.ntp.org/bin/view/Main/NtpBug3046 http://support.ntp.org/bin/view/Main/SecurityNot • CWE-476: NULL Pointer Dereference •
