QEMU (aka Quick Emulator), when built with VMWARE PVSCSI paravirtual SCSI bus emulation support, allows local guest OS administrators to cause a denial of service (out-of-bounds array access) via vectors related to the (1) PVSCSI_CMD_SETUP_RINGS or (2) PVSCSI_CMD_SETUP_MSG_RING SCSI command. QEMU (también conocido como Quick Emulator), cuando está construido con soporte de emulación bus VMWARE PVSCSI paravirtual SCSI, permite a administradores locales del SO invitado provocar una denegación de servicio (acceso al array fuera de rango) a través de vectores relacionados con el comando (1) PVSCSI_CMD_SETUP_RINGS o (2) PVSCSI_CMD_SETUP_MSG_RING SCSI. • http://www.openwall.com/lists/oss-security/2016/05/23/1 http://www.openwall.com/lists/oss-security/2016/05/23/4 http://www.ubuntu.com/usn/USN-3047-1 http://www.ubuntu.com/usn/USN-3047-2 https://bugzilla.redhat.com/show_bug.cgi?id=1334384 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg03774.html • CWE-787: Out-of-bounds Write •

The megasas_dcmd_cfg_read function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, uses an uninitialized variable, which allows local guest administrators to read host memory via vectors involving a MegaRAID Firmware Interface (MFI) command. La función megasas_dcmd_cfg_read en hw/scsi/megasas.c en QEMU, cuando está construido con el soporte de emulación MegaRAID SAS 8708EM2 Host Bus Adapter, utiliza una variable sin inicializar, lo que permite a administradores locales invitados leer memoria de anfitrión a través de vectores que implican un comando MegaRAID Firmware Interface (MFI). • http://www.openwall.com/lists/oss-security/2016/05/25/5 http://www.openwall.com/lists/oss-security/2016/05/26/7 http://www.ubuntu.com/usn/USN-3047-1 http://www.ubuntu.com/usn/USN-3047-2 https://bugzilla.redhat.com/show_bug.cgi?id=1339583 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg04419.html • CWE-908: Use of Uninitialized Resource •
CVSS: 5.5EPSS: 0%CPEs: 38EXPL: 0CVE-2016-5403 – Qemu: virtio: unbounded memory allocation on host via guest leading to DoS
https://notcve.org/view.php?id=CVE-2016-5403
The virtqueue_pop function in hw/virtio/virtio.c in QEMU allows local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) by submitting requests without waiting for completion. La función virtqueue_pop en hw/virtio/virtio.c en QEMU permite a administradores locales del SO invitado provocar una denegación de servicio (consumo de memoria y caida del proceso QUEMU) mediante la presentación de solicitudes sin esperar la finalización. Quick Emulator (QEMU) built with the virtio framework is vulnerable to an unbounded memory allocation issue. It was found that a malicious guest user could submit more requests than the virtqueue size permits. Processing a request allocates a VirtQueueElement results in unbounded memory allocation on the host controlled by the guest. • http://rhn.redhat.com/errata/RHSA-2016-1585.html http://rhn.redhat.com/errata/RHSA-2016-1586.html http://rhn.redhat.com/errata/RHSA-2016-1606.html http://rhn.redhat.com/errata/RHSA-2016-1607.html http://rhn.redhat.com/errata/RHSA-2016-1652.html http://rhn.redhat.com/errata/RHSA-2016-1653.html http://rhn.redhat.com/errata/RHSA-2016-1654.html http://rhn.redhat.com/errata/RHSA-2016-1655.html http://rhn.redhat.com/errata/RHSA-2016-1756.html http://rhn • CWE-400: Uncontrolled Resource Consumption •
