CVE-2015-5219 – ntp: infinite loop in sntp processing crafted packet
https://notcve.org/view.php?id=CVE-2015-5219
The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet. La función ULOGTOD en el archivo ntp.d en SNTP en versiones anteriores a la 4.2.7p366 no realiza apropiadamente las conversiones de tipo de un valor de precisión a uno doble, lo que permite a los atacantes remotos causar una denegación de servicio (bucle infinito) por medio de un paquete NTP creado. It was discovered that the sntp utility could become unresponsive due to being caught in an infinite loop when processing a crafted NTP packet. • http://aix.software.ibm.com/aix/efixes/security/ntp_advisory4.asc http://bk1.ntp.org/ntp-dev/?PAGE=patch&REV=51786731Gr4-NOrTBC_a_uXO4wuGhg http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169167.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/166992.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00048.html http://lists.opensuse.org/opensuse-updates • CWE-704: Incorrect Type Conversion or Cast CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2015-5300 – ntp: MITM attacker can force ntpd to make a step larger than the panic threshold
https://notcve.org/view.php?id=CVE-2015-5300
The panic_gate check in NTP before 4.2.8p5 is only re-enabled after the first change to the system clock that was greater than 128 milliseconds by default, which allows remote attackers to set NTP to an arbitrary time when started with the -g option, or to alter the time by up to 900 seconds otherwise by responding to an unspecified number of requests from trusted sources, and leveraging a resulting denial of service (abort and restart). La comprobación panic_gate en NTP anterior a versión 4.2.8p5 es solo habilitada nuevamente después del primer cambio al reloj del sistema que fue mayor que 128 milisegundos por defecto, permitiendo a los atacantes remotos fijar el NTP a un tiempo arbitrario cuando arranca con la opción -g, o alterar el tiempo hasta 900 segundos, de lo contrario por respuesta a un número no especificado de peticiones de fuentes de confianza y aprovechando una denegación de servicio resultante (anular y reiniciar). It was found that ntpd did not correctly implement the threshold limitation for the '-g' option, which is used to set the time without any restrictions. A man-in-the-middle attacker able to intercept NTP traffic between a connecting client and an NTP server could use this flaw to force that client to make multiple steps larger than the panic threshold, effectively changing the time to an arbitrary value at any time. • http://aix.software.ibm.com/aix/efixes/security/ntp_advisory5.asc http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170684.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177507.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-announc • CWE-20: Improper Input Validation CWE-361: 7PK - Time and State •
CVE-2015-5271 – openstack-tripleo-heat-templates: unsafe pipeline ordering of swift staticweb middleware
https://notcve.org/view.php?id=CVE-2015-5271
The TripleO Heat templates (tripleo-heat-templates) do not properly order the Identity Service (keystone) before the OpenStack Object Storage (Swift) staticweb middleware in the swiftproxy pipeline when the staticweb middleware is enabled, which might allow remote attackers to obtain sensitive information from private containers via unspecified vectors. Las plantillas TripleO Heat (tripleo-heat-templates) no ordena correctamente el Identity Service (keystone) en versiones anteriores al middleware de web estática OpenStack Object Storage (Swift) en el pipeline de swiftproxy cuando el middleware de web estática está habilitado, lo que podría permitir a atacantes remotos obtener información sensible de contenedores privados a través de vectores no especificados. A flaw was discovered in the pipeline ordering of OpenStack Object Storage's staticweb middleware in the swiftproxy configuration generated from the openstack-tripleo-heat-templates package (OpenStack director). The staticweb middleware was incorrectly configured before the Identity Service, and under some conditions an attacker could use this flaw to gain unauthenticated access to private data. • https://access.redhat.com/errata/RHSA-2015:1862 https://bugs.launchpad.net/tripleo/+bug/1494896 https://bugzilla.redhat.com/show_bug.cgi?id=1261697 https://launchpadlibrarian.net/217268516/CVE-2015-5271_puppet-swift.patch https://access.redhat.com/security/cve/CVE-2015-5271 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-285: Improper Authorization •
CVE-2015-6815

The process_tx_desc function in hw/net/e1000.c in QEMU before 2.4.0.1 does not properly process transmit descriptor data when sending a network packet, which allows attackers to cause a denial of service (infinite loop and guest crash) via unspecified vectors. La función process_tx_desc en el archivo hw/net/e1000.c en QEMU versiones anteriores a 2.4.0.1, no procesa apropiadamente los datos del descriptor de transmisión cuando se envía un paquete de red, lo que permite a atacantes causar una denegación de servicio (bucle infinito y bloqueo de invitado) por medio de vectores no especificados. • http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168077.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168646.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168671.html http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2015-11/msg00011.html http://www.openwall.com/lists/oss-security • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2015-5225 – Qemu: ui: vnc: heap memory corruption in vnc_refresh_server_surface
https://notcve.org/view.php?id=CVE-2015-5225
Buffer overflow in the vnc_refresh_server_surface function in the VNC display driver in QEMU before 2.4.0.1 allows guest users to cause a denial of service (heap memory corruption and process crash) or possibly execute arbitrary code on the host via unspecified vectors, related to refreshing the server display surface. Desbordamiento de buffer en la función vnc_refresh_server_surface en el controlador de pantalla VNC en QEMU en versiones anteriores a 2.4.0.1 permite a usuarios invitados provocar una denegación de servicio (corrupción de memoria dinámica y caída de proceso) o posiblemente ejecutar código arbitrario en el host a través de vectores no especificados, relacionado con la actualización de la superficie mostrada en el servidor. A heap-based buffer overflow issue was found in the QEMU emulator's VNC display driver. It could occur while refreshing the VNC server's display surface using the vnc_refresh_server_surface() routine. A privileged guest user could use this flaw to corrupt the heap memory and crash the QEMU process instance, or to potentially use it to execute arbitrary code on the host. • http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169039.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/165484.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/166798.html http://rhn.redhat.com/errata/RHSA-2015-1772.html http://rhn.redhat.com/errata/RHSA-2015-1837.html http://www.debian.org/security/2015/dsa-3348 http://www.openwall.com/lists/oss-security/2015/08/21/6 http://www.securityfocus.com/bid/76506 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •
