hw/virtio/virtio.c in the Virtual Network Device (virtio-net) support in QEMU, when big or mergeable receive buffers are not supported, allows remote attackers to cause a denial of service (guest network consumption) via a flood of jumbo frames on the (1) tuntap or (2) macvtap interface. hw/virtio/virtio.c en el soporte Virtual Network Device (virtio-net) en QEMU, cuando buffers de recepción de gran tamaño o fusionables no son soportados, permite a atacantes remotos causar una denegación de servicio (consumo de la red de invitado) a través de una inundación de marcos jumbo en la interfaz (1) tuntap o (2) macvtap. • http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169624.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169767.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169802.html http://www.debian.org/security/2016/dsa-3469 http://www.debian.org/security/2016/dsa-3470 http://www.debian.org/security/2016/dsa-3471 http://www.openwall.com/lists/oss-security/2015/09/18/5 http://www.openwall.com/lists/oss-security/2015&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.2EPSS: 0%CPEs: 1EXPL: 0CVE-2015-5279 – qemu: Heap overflow vulnerability in ne2000_receive() function
https://notcve.org/view.php?id=CVE-2015-5279
Heap-based buffer overflow in the ne2000_receive function in hw/net/ne2000.c in QEMU before 2.4.0.1 allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via vectors related to receiving packets. Desbordamiento de buffer basado en memoria dinámica en la función ne2000_receive en hw/net/ne2000.c en QEMU en versiones anteriores a 2.4.0.1, permite a usuarios invitados del SO provocar una denegación de servicio (caída de la instancia) o posiblemente ejecutar código arbitrario a través de vectores relacionados con la recepción de paquetes. A heap buffer overflow flaw was found in the way QEMU's NE2000 NIC emulation implementation handled certain packets received over the network. A privileged user inside a guest could use this flaw to crash the QEMU instance (denial of service) or potentially execute arbitrary code on the host. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=7aa2bcad0ca837dd6d4bf4fa38a80314b4a6b755 http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169036.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169039.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/167369.html http://lists.opensuse.org/opensuse-security-announce/2015-10/msg00019.html http://rhn.redhat.com/errata/RHSA-2015-1896.html http://rhn.redhat.com/errata/RHSA-2015-1923.html ht • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash. hw/ide/core.c en QEMU no restringe adecuadamente los comandos aceptados por un dispositivo ATAPI, lo que permite a usuarios invitados provocar una denegación de servicio o posiblemente tener otro impacto no especificado a través de ciertos comandos IDE, según lo demostrado por un comando WIN_READ_NATIVE_MAX en un controlador vacío, lo cual desencadena un error de división por cero y una cáida de la instancia. • http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168602.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169036.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169039.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169327.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/169341.html http://lists.fedoraproject.org/pipermail/package-announce/2015-September/167369.html http://lists.opensuse.org/ • CWE-369: Divide By Zero •
