flaws were found in the way the virtio, virtio-net, virtio-scsi, and

to alter the savevm data (either on the disk or over the wire during

arbitrary code execution on the host with the privileges of the QEMU
process. (CVE-2013-4148, CVE-2013-4151, CVE-2013-4535, CVE-2013-4536,
CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182,
CVE-2014-3461)

An out-of-bounds memory access flaw was found in the way QEMU's IDE
device driver handled the execution of SMART EXECUTE OFFLINE commands.
A privileged guest user could use this flaw to corrupt QEMU process
memory on the host, which could potentially result in arbitrary code
execution on the host with the privileges of the QEMU process.
(CVE-2014-2894)

This update also fixes the following bugs :

  - Previously, under certain circumstances, libvirt failed
    to start guests which used a non-zero PCI domain and
    SR-IOV Virtual Functions (VFs), and returned the
    following error message :

Can't assign device inside non-zero PCI segment as this KVM module
doesn't support it.

This update fixes this issue and guests using the aforementioned
configuration no longer fail to start.

  - Due to an incorrect initialization of the cpus_sts
    bitmap, which holds the enablement status of a vCPU,
    libvirt could fail to start a guest with an unusual vCPU
    topology (for example, a guest with three cores and two
    sockets). With this update, the initialization of
    cpus_sts has been corrected, and libvirt no longer fails
    to start the aforementioned guests.

After installing this update, shut down all running virtual machines.
Once all virtual machines have shut down, start them again for this
update to take effect."

The Red Hat Security Response Team has rated this update as having
Moderate security impact. Common Vulnerability Scoring System (CVSS)
base scores, which give detailed severity ratings, are available for
each vulnerability from the CVE links in the References section.

KVM (Kernel-based Virtual Machine) is a full virtualization solution
for Linux on AMD64 and Intel 64 systems. The qemu-kvm package provides
the user-space component for running virtual machines using KVM.

Multiple buffer overflow, input validation, and out-of-bounds write
flaws were found in the way the virtio, virtio-net, virtio-scsi, and
usb drivers of QEMU handled state loading after migration. A user able
to alter the savevm data (either on the disk or over the wire during
migration) could use either of these flaws to corrupt QEMU process
memory on the (destination) host, which could potentially result in
arbitrary code execution on the host with the privileges of the QEMU
process. (CVE-2013-4148, CVE-2013-4151, CVE-2013-4535, CVE-2013-4536,

A privileged guest user could use this flaw to corrupt QEMU process
memory on the host, which could potentially result in arbitrary code

The CVE-2013-4148, CVE-2013-4151, CVE-2013-4535, CVE-2013-4536,
CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182, and
CVE-2014-3461 issues were discovered by Michael S. Tsirkin of Red Hat,
Anthony Liguori, and Michael Roth.

This update also fixes the following bugs :

* Previously, under certain circumstances, libvirt failed to start
guests which used a non-zero PCI domain and SR-IOV Virtual Functions
(VFs), and returned the following error message :

Can't assign device inside non-zero PCI segment as this KVM module

* Due to an incorrect initialization of the cpus_sts bitmap, which
holds the enablement status of a vCPU, libvirt could fail to start a
guest with an unusual vCPU topology (for example, a guest with three
cores and two sockets). With this update, the initialization of
cpus_sts has been corrected, and libvirt no longer fails to start the

All qemu-kvm users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. After
installing this update, shut down all running virtual machines. Once
all virtual machines have shut down, start them again for this update
to take effect."

"Updated qemu packages fix security vulnerabilities :

Michael S. Tsirkin discovered that QEMU incorrectly handled vmxnet3
devices. A local guest could possibly use this issue to cause a denial
of service, or possibly execute arbitrary code on the host
(CVE-2013-4544).

Multiple integer overflow, input validation, logic error, and buffer
overflow flaws were discovered in various QEMU block drivers. An
attacker able to modify a disk image file loaded by a guest could use
these flaws to crash the guest, or corrupt QEMU process memory on the
host, potentially resulting in arbitrary code execution on the host
with the privileges of the QEMU process (CVE-2014-0143, CVE-2014-0144,
CVE-2014-0145, CVE-2014-0147).

A buffer overflow flaw was found in the way the
virtio_net_handle_mac() function of QEMU processed guest requests to
update the table of MAC addresses. A privileged guest user could use
this flaw to corrupt QEMU process memory on the host, potentially
resulting in arbitrary code execution on the host with the privileges
of the QEMU process (CVE-2014-0150).

A divide-by-zero flaw was found in the seek_to_sector() function of
the parallels block driver in QEMU. An attacker able to modify a disk
image file loaded by a guest could use this flaw to crash the guest
(CVE-2014-0142).

A NULL pointer dereference flaw was found in the QCOW2 block driver in
QEMU. An attacker able to modify a disk image file loaded by a guest
could use this flaw to crash the guest (CVE-2014-0146).

It was found that the block driver for Hyper-V VHDX images did not
correctly calculate BAT (Block Allocation Table) entries due to a
missing bounds check. An attacker able to modify a disk image file
loaded by a guest could use this flaw to crash the guest
(CVE-2014-0148).

An out-of-bounds memory access flaw was found in the way QEMU's IDE
device driver handled the execution of SMART EXECUTE OFFLINE commands.
A privileged guest user could use this flaw to corrupt QEMU process
memory on the host, which could potentially result in arbitrary code
execution on the host with the privileges of the QEMU process
(CVE-2014-2894).

Two integer overflow flaws were found in the QEMU block driver for
QCOW version 1 disk images. A user able to alter the QEMU disk image
files loaded by a guest could use either of these flaws to corrupt
QEMU process memory on the host, which could potentially result in
arbitrary code execution on the host with the privileges of the QEMU
process (CVE-2014-0222, CVE-2014-0223).

Multiple buffer overflow, input validation, and out-of-bounds write
flaws were found in the way the virtio, virtio-net, virtio-scsi, and
usb drivers of QEMU handled state loading after migration. A user able
to alter the savevm data (either on the disk or over the wire during
migration) could use either of these flaws to corrupt QEMU process
memory on the (destination) host, which could potentially result in
arbitrary code execution on the host with the privileges of the QEMU
process (CVE-2013-4148, CVE-2013-4151, CVE-2013-4535, CVE-2013-4536,
CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182,
CVE-2014-3461).

An information leak flaw was found in the way QEMU's VGA emulator
accessed frame buffer memory for high resolution displays. A
privileged guest user could use this flaw to leak memory contents of
the host to the guest by setting the display to use a high resolution
in the guest (CVE-2014-3615).

When guest sends udp packet with source port and source addr 0,
uninitialized socket is picked up when looking for matching and
already created udp sockets, and later passed to sosendto() where NULL
pointer dereference is hit during so->slirp->vnetwork_mask.s_addr
access Only guests using qemu user networking are affected
(CVE-2014-3640).

The Advanced Threat Research team at Intel Security reported that
guest provided parameter were insufficiently validated in rectangle
functions in the vmware-vga driver. A privileged guest user could use
this flaw to write into qemu address space on the host, potentially
escalating their privileges to those of the qemu host process
(CVE-2014-3689).

It was discovered that QEMU incorrectly handled USB xHCI controller
live migration. An attacker could possibly use this issue to cause a
denial of service, or possibly execute arbitrary code (CVE-2014-5263).

James Spadaro of Cisco reported insufficiently sanitized
bits_per_pixel from the client in the QEMU VNC display driver. An
attacker having access to the guest's VNC console could use this flaw
to crash the guest (CVE-2014-7815).

Additionally qemu-1.6+ requires usbredir-0.6+ for USB redirection
support which is also being provided with this advisory."
