https://notcve.org/view.php?id=CVE-2015-7504
Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode. Desbordamiento de búfer basado en memoria dinámica (heap) en la función pcnet_receive en hw/net/pcnet.c en QEMU permite que administradores del sistema operativo invitados provoquen una denegación de servicio (cierre inesperado de la instancia) o que puedan ejecutar código arbitrario mediante una serie de paquetes en modo de bucle invertido. A heap-based buffer overflow flaw was discovered in the way QEMU's AMD PC-Net II Ethernet Controller emulation received certain packets in loopback mode. A privileged user (with the CAP_SYS_RAWIO capability) inside a guest could use this flaw to crash the host QEMU process (resulting in denial of service) or, potentially, execute arbitrary code with privileges of the host QEMU process. • http://rhn.redhat.com/errata/RHSA-2015-2694.html http://rhn.redhat.com/errata/RHSA-2015-2695.html http://rhn.redhat.com/errata/RHSA-2015-2696.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/2015/11/30/2 http://www.securityfocus.com/bid/78227 http://www.securitytracker.com/id/1034268 http://xenbits.xen.org/xsa/advisory • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

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 •

Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENT_CUT_TEXT message, which triggers an infinite loop. Un desbordamiento de enteros en el controlador de pantalla VNC en QEMU versiones anteriores a 2.1.0, permite a atacantes causar una denegación de servicio (bloqueo del proceso) mediante un mensaje CLIENT_CUT_TEXT, que desencadena un bucle infinito. • 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&#x • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

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&#x • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
