QEMU (aka Quick Emulator) built with a VMWARE VMXNET3 paravirtual NIC emulator support is vulnerable to crash issue. It occurs when a guest sends a Layer-2 packet smaller than 22 bytes. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance resulting in DoS. QEMU (también conocido como Quick Emulator) construido con un soporte de emulador VMWARE VMXNET3 paravirtual NIC es vulnerable a un problema de caída. Ocurre cuando un invitado envía un paquete Layer-2 más pequeño que 22 bytes. • http://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=a7278b36fcab9af469563bd7b http://www.debian.org/security/2016/dsa-3471 http://www.openwall.com/lists/oss-security/2016/01/04/3 http://www.openwall.com/lists/oss-security/2016/01/04/6 http://www.securityfocus.com/bid/79821 http://www.securitytracker.com/id/1034576 https://bugzilla.redhat.com/show_bug.cgi?id=1270871 https://security.gentoo.org/glsa/201602-01 • CWE-20: Improper Input Validation •

The ehci_process_itd function in hw/usb/hcd-ehci.c in QEMU allows local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via a circular isochronous transfer descriptor (iTD) list. La función ehci_process_itd en hw/usb/hcd-ehci.c en QEMU permite a administradores de SO locales invitados provocar una denegación de servicio (bucle infinito y consumo de CPU) a través de una lista iTD (de descriptor de transferencia isócrona) circular. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=156a2e4dbffa85997636a7a39ef12da6f1b40254 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/2015/12/14/16 http://www.openwall.com/lists/oss-security/2015/12/14/9 http://www.securityfocus.com/bid/80694 https://bugzilla.redhat.com/show_bug.cgi?id=1277983 https://lists.gnu.org/archive/html/qemu • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 8.8EPSS: 0%CPEs: 8EXPL: 0CVE-2016-1568 – Qemu: ide: ahci use-after-free vulnerability in aio port commands
https://notcve.org/view.php?id=CVE-2016-1568
Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command. Vulnerabilidad de uso después de liberación de memoria en hw/ide/ahci.c en QEMU, cuando se construye con soporte de emulación IDE AHCI, permite a usuarios del SO invitado causar una denegación de servicio (caída de instancia) o posiblemente ejecutar código arbitrario a través de un comando AHCI Native Command Queuing (NCQ) AIO no válido. A use-after-free flaw was found in the way QEMU's IDE AHCI emulator processed certain AHCI Native Command Queuing (NCQ) AIO commands. A privileged guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=4ab0359a8ae182a7ac5c99609667273167703fab http://rhn.redhat.com/errata/RHSA-2016-0084.html http://rhn.redhat.com/errata/RHSA-2016-0086.html http://rhn.redhat.com/errata/RHSA-2016-0087.html http://rhn.redhat.com/errata/RHSA-2016-0088.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/2016/0 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2016-1714
The (1) fw_cfg_write and (2) fw_cfg_read functions in hw/nvram/fw_cfg.c in QEMU before 2.4, when built with the Firmware Configuration device emulation support, allow guest OS users with the CAP_SYS_RAWIO privilege to cause a denial of service (out-of-bounds read or write access and process crash) or possibly execute arbitrary code via an invalid current entry value in a firmware configuration. Las funciones (1) fw_cfg_write y (2) fw_cfg_read en hw/nvram/fw_cfg.c en QEMU en versiones anteriores a 2.4, cuando construye con el soporte de emulación de dispositivo de Firmware Configuration, permiten a usuarios del SO invitado con el privilegio CAP_SYS_RAWIO provocar una denegación de servicio (acceso a lectura o escritura fuera de rango y caída del proceso) o potencialmente ejecutar código arbitrario a través de un valor de entrada actual no válido en una configuración de firmware. An out-of-bounds read/write flaw was discovered in the way QEMU's Firmware Configuration device emulation processed certain firmware configurations. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance or, potentially, execute arbitrary code on the host with privileges of the QEMU process. • http://rhn.redhat.com/errata/RHSA-2016-0081.html http://rhn.redhat.com/errata/RHSA-2016-0082.html http://rhn.redhat.com/errata/RHSA-2016-0083.html http://rhn.redhat.com/errata/RHSA-2016-0084.html http://rhn.redhat.com/errata/RHSA-2016-0085.html http://rhn.redhat.com/errata/RHSA-2016-0086.html http://rhn.redhat.com/errata/RHSA-2016-0087.html http://rhn.redhat.com/errata/RHSA-2016-0088.html http://www.debian.org/security/2016/dsa-3469 http://www.debia • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
