Xen 3.3.x through 4.5.x does not properly restrict write access to the host MSI message data field, which allows local x86 HVM guest administrators to cause a denial of service (host interrupt handling confusion) via vectors related to qemu and accessing spanning multiple fields. Xen 3.3.x hasta la versión 4.5.x no restringe correctamente el acceso a escritura al campo de datos del mensaje MSI del host, lo que permite a administradores invitados x86 HVM locales causar una denegación de servicio (confusión en el manejo de interrupción de host) a través de vectores relacionados con qemu y accediendo a múltiples campos de expansión. • 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-264: Permissions, Privileges, and Access Controls •

Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service (unexpected interrupt and host crash) via unspecified vectors. Xen 3.3.x hasta 4.5.x no restringe correctamente el acceso a los bits de máscara PCI MSI, lo que permite a usuarios locales invitados de x86 HVM causar una denegación de servicio (interrupción no esperado y caída de anfitrión) a través de vectores no especificados. • 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-264: Permissions, Privileges, and Access Controls •

Xen 3.3.x through 4.5.x enables logging for PCI MSI-X pass-through error messages, which allows local x86 HVM guests to cause a denial of service (host disk consumption) via certain invalid operations. Xen 3.3.x hasta 4.5.x habilita el registro para mensajes de error 'pass-through' de PCI MSI-X, lo que permite a invitados locales de x86 HVM causar una denegación de servicio (consumo de disco de anfitrión) a través de ciertas operaciones inválidas. • 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-399: Resource Management Errors •
CVSS: 7.7EPSS: 0%CPEs: 10EXPL: 1CVE-2015-3456 – QEMU - Floppy Disk Controller (FDC) (PoC)
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 •
