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 •

Heap-based buffer overflow in SPICE before 0.12.6 allows guest OS users to cause a denial of service (heap-based memory corruption and QEMU-KVM crash) or possibly execute arbitrary code on the host via QXL commands related to the surface_id parameter. Desbordamiento de buffer basado en memoria dinámica en SPICE en versiones anteriores a 0.12.6 permite a usuarios invitados del SO provocar una denegación de servicio (corrupción basada en memoria dinámica y caída de QEMu-KVM) o posiblemente ejecutar código arbitrario en el anfitrión a través de comandos QXL relacionados con el parámetro surface_id . A heap-based buffer overflow flaw was found in the way spice handled certain QXL commands related to the "surface_id" parameter. A user in a guest could use this flaw to crash the host QEMU-KVM process or, possibly, execute arbitrary code with the privileges of the host QEMU-KVM process. • http://lists.freedesktop.org/archives/spice-devel/2015-October/022191.html http://rhn.redhat.com/errata/RHSA-2015-1889.html http://rhn.redhat.com/errata/RHSA-2015-1890.html http://www.debian.org/security/2015/dsa-3371 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/77019 http://www.securitytracker.com/id/1033753 http://www.ubuntu.com/usn/USN-2766-1 https://bugzilla.redhat.com/show_bug.cgi?id=1260822 https:&# • CWE-20: Improper Input Validation CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Heap-based buffer overflow in SPICE before 0.12.6 allows guest OS users to read and write to arbitrary memory locations on the host via guest QXL commands related to surface creation. Desbordamiento de buffer basado en memoria dinámica en SPICE en versiones anteriores a 0.12.6 permite a usuarios invitados del SO leer y escribir en localizaciones de memoria arbitrarias en el anfitrión a través de comandos QXL de invitado relacionados con la creación de superficie. A heap-based buffer overflow flaw was found in the way SPICE handled certain guest QXL commands related to surface creation.

The C+ mode offload emulation in the RTL8139 network card device model in QEMU, as used in Xen 4.5.x and earlier, allows remote attackers to read process heap memory via unspecified vectors. Vulnerabilidad en la emulación de modo offload C+ en el modelo de tarjeta de red del dispositivo RTL8139 en QEMU, tal y como se utiliza en Xen 4.5.x y versiones anteriores, permite a atacantes remotos leer la memoria dinámica del proceso a través de vectores no especificados. An information leak flaw was found in the way QEMU's RTL8139 emulation implementation processed network packets under RTL8139 controller's C+ mode of operation. An unprivileged guest user could use this flaw to read up to 65 KB of uninitialized QEMU heap memory. • http://lists.fedoraproject.org/pipermail/package-announce/2015-September/165373.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/167792.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/167820.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00027.html http://rhn.redhat.com/errata/RHSA-2015-1674.html http://rhn.redhat.com/errata/RHSA-2015-1683.html http: • CWE-456: Missing Initialization of a Variable CWE-908: Use of Uninitialized Resource •

The PDF reader in Mozilla Firefox before 39.0.3, Firefox ESR 38.x before 38.1.1, and Firefox OS before 2.2 allows remote attackers to bypass the Same Origin Policy, and read arbitrary files or gain privileges, via vectors involving crafted JavaScript code and a native setter, as exploited in the wild in August 2015. Vulnerabilidad en el lector de PDF en Mozilla Firefox en versiones anteriores a 39.0.3, Firefox ESR 38.x en versiones anteriores a 38.1.1 y Firefox OS en versiones anteriores a 2.2, permite a atacantes remotos eludir la Same Origin Policy y leer archivos arbitrarios u obtener privilegios a través de vectores que implican código JavaScript manipulado y un setter nativo, tal como se explotó activamente en agosto de 2015. A flaw was discovered in Mozilla Firefox that could be used to violate the same-origin policy and inject web script into a non-privileged part of the built-in PDF file viewer (PDF.js). An attacker could create a malicious web page that, when viewed by a victim, could steal arbitrary files (including private SSH keys, the /etc/passwd file, and other potentially sensitive files) from the system running Firefox. Moxilla Firefox allows remote attackers to bypass the Same Origin Policy to read arbitrary files or gain privileges. • https://www.exploit-db.com/exploits/37772 https://github.com/vincd/CVE-2015-4495 http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2015-08/msg00021.html http://lists.opensuse.org/opensuse-security- •
