The slirp_smb function in net/slirp.c in QEMU 2.3.0 and earlier creates temporary files with predictable names, which allows local users to cause a denial of service (instantiation failure) by creating /tmp/qemu-smb.*-* files before the program. Vulnerabilidad en la función slirp_smb en net/slirp.c en QEMU 2.3.0 y en versiones anteriores, crea archivos temporales con nombres predecibles, lo que permite a usuarios locales causar una denegación de servicio (fallo en la instanciación) creando archivos /tmp/qemu-smb.*-* antes que el programa. • http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160058.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160414.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00015.html http://lists.opensuse.org/opensuse-updates/2015-11/msg00063.html http://www.debian.org/security/2015/dsa-3284 http://www.debian.org/security/2015/dsa-3285 http://www.openwall.com/lists/ • CWE-17: DEPRECATED: Code •
CVSS: 7.5EPSS: 7%CPEs: 36EXPL: 0CVE-2015-3209 – qemu: pcnet: multi-tmd buffer overflow in the tx path
https://notcve.org/view.php?id=CVE-2015-3209
Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set. Desbordamiento de buffer basado en memoria dinámica en el controlador PCNET en QEMU permite a atacantes remotos ejecutar código arbitrario mediante el envío de un paquete con el juego TXSTATUS_STARTPACKET y posteriormente un paquete manipulado con el juego TXSTATUS_DEVICEOWNS. A flaw was found in the way QEMU's AMD PCnet Ethernet emulation handled multi-TMD packets with a length above 4096 bytes. A privileged guest user in a guest with an AMD PCNet ethernet card enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process. • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10698 http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160669.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160677.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160685.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •

QEMU does not properly restrict write access to the PCI config space for certain PCI pass-through devices, which might allow local x86 HVM guests to gain privileges, cause a denial of service (host crash), obtain sensitive information, or possibly have other unspecified impact via unknown vectors. QEMU no restringe correctamente el acceso a escritura al espacio PCI config para ciertos dispositivos PCI pass-through, lo que podría permitir a invitados x86 HVM locales obtener privilegios, causar una denegación de servicio (caída de host), obtener información sensible o posiblemente tener otro impacto no especificado a través de vectores desconocidos. • http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160154.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160171.html http://lists.fedoraproject.org/pipermail/package-announce/2015-June/160685.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-06/msg00029.html http://lists.opensuse.org/opensuse-security-announce&#x • CWE-863: Incorrect Authorization •

https://notcve.org/view.php?id=CVE-2015-3456
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM. Floppy Disk Controller (FDC) en QEMU, utilizado en Xen 4.5.x y anteriores y KVM, permite a usuarios locales invitados causar una denegación de servicio (escritura fuera de rango y caída del invitado) o posiblemente ejecutar código arbitrario a través de (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, u otros comandos sin especificar, también conocido como VENOM. An out-of-bounds memory access flaw was found in the way QEMU's virtual Floppy Disk Controller (FDC) handled FIFO buffer access while processing certain FDC commands. A privileged guest user could use this flaw to crash the guest or, potentially, execute arbitrary code on the host with the privileges of the host's QEMU process corresponding to the guest. • https://www.exploit-db.com/exploits/37053 http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=e907746266721f305d67bc0718795fedee2e824c http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10693 http://lists.fedoraproject.org/pipermail/package-announce/2015-May/158072.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00014.html http:/&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2015-1779
The VNC websocket frame decoder in QEMU allows remote attackers to cause a denial of service (memory and CPU consumption) via a large (1) websocket payload or (2) HTTP headers section. El decodificador de frames websocket VNC en QEMU permite a atacantes remotos causar una denegación de servicio (consumo de CPU y memoria) a través de una gran (1) carga útil websocket o (2) sección de cabeceras HTTP It was found that the QEMU's websocket frame decoder processed incoming frames without limiting resources used to process the header and the payload. An attacker able to access a guest's VNC console could use this flaw to trigger a denial of service on the host by exhausting all available memory and CPU. • http://lists.fedoraproject.org/pipermail/package-announce/2015-April/154656.html http://lists.fedoraproject.org/pipermail/package-announce/2015-April/155196.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2015-05/msg00042.html http://rhn.redhat.com/errata/RHSA-2015-1931.html http://rhn.redhat.com/errata/RHSA-2015-1943.html http://www.debian.org/security/2015/dsa-3259 http://www.openwall.com/lists/oss-secu • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
