    allow enabling/disabling branch prediction features in
    the Intel CPU. (bsc#1068032) Security fixes have been

"Security Fix(es) :

  - A heap buffer overflow flaw was found in QEMU's Cirrus
    CLGD 54xx VGA emulator's VNC display driver support; the
    issue could occur when a VNC client attempted to update
    its display after a VGA operation is performed by a
    guest. A privileged user/process inside a guest could
    use this flaw to crash the QEMU process or, potentially,
    execute arbitrary code on the host with privileges of
    the QEMU process. (CVE-2016-9603)

  - An out-of-bounds r/w access issue was found in QEMU's
    Cirrus CLGD 54xx VGA Emulator support. The vulnerability
    could occur while copying VGA data via various bitblt
    functions. A privileged user inside a guest could use
    this flaw to crash the QEMU process or, potentially,
    execute arbitrary code on the host with privileges of
    the QEMU process. (CVE-2017-7980)

  - An out-of-bounds memory access issue was found in QEMU's
    VNC display driver support. The vulnerability could
    occur while refreshing the VNC display surface area in
    the 'vnc_refresh_server_surface'. A user/process inside
    a guest could use this flaw to crash the QEMU process,
    resulting in a denial of service. (CVE-2017-2633)

  - An out-of-bounds access issue was found in QEMU's Cirrus
    CLGD 54xx VGA Emulator support. The vulnerability could
    occur while copying VGA data using bitblt functions (for
    example, cirrus_bitblt_rop_fwd_transp_). A privileged

"This update for xen fixes the following issues: These security issues
were fixed :

  - CVE-2017-7228: Broken check in memory_exchange()
    permited PV guest breakout (bsc#1030442).

  - XSA-206: Unprivileged guests issuing writes to xenstore
    were able to stall progress of the control domain or
    driver domain, possibly leading to a Denial of Service
    (DoS) of the entire host (bsc#1030144).

  - CVE-2017-6505: The ohci_service_ed_list function in
    hw/usb/hcd-ohci.c allowed local guest OS users to cause
    a denial of service (infinite loop) via vectors
    involving the number of link endpoint list descriptors
    (bsc#1028235).

  - CVE-2017-6414: Memory leak in the vcard_apdu_new
    function in card_7816.c in libcacard allowed local guest
    OS users to cause a denial of service (host memory
    consumption) via vectors related to allocating a new
    APDU object (bsc#1027570).

  - CVE-2017-2633: The VNC display driver support was
    vulnerable to an out-of-bounds memory access issue. A
    user/process inside guest could use this flaw to cause
    DoS (bsc#1026636).

  - CVE-2016-9603: A privileged user within the guest VM can
    cause a heap overflow in the device model process,
    potentially escalating their privileges to that of the
    device model process (bsc#1028655).

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

    (bsc#1021741)

  - CVE-2017-9503: The MegaRAID SAS 8708EM2 Host Bus Adapter
    emulation support was vulnerable to a NULL pointer
    dereference issue which allowed a privileged user inside
    guest to crash the Qemu process on the host resulting in
    DoS (bsc#1043296)

  - CVE-2017-10664: qemu-nbd did not ignore SIGPIPE, which
    allowed remote attackers to cause a denial of service
    (daemon crash) by disconnecting during a
    server-to-client reply attempt (bsc#1046636)

  - CVE-2017-10806: Stack-based buffer overflow allowed
    local guest OS users to cause a denial of service (QEMU
    process crash) via vectors related to logging debug
    messages (bsc#1047674)

  - CVE-2016-9602: The VirtFS host directory sharing via
    Plan 9 File System(9pfs) support was vulnerable to an
    improper link following issue which allowed a privileged
    user inside guest to access host file system beyond the
    shared folder and potentially escalating their
    privileges on a host (bsc#1020427)

  - CVE-2017-7377: The v9fs_create and v9fs_lcreate
    functions in hw/9pfs/9p.c allowed local guest OS
    privileged users to cause a denial of service (file
    descriptor or memory consumption) via vectors related to
    an already in-use fid (bsc#1032075)

  - CVE-2017-8086: A memory leak in the v9fs_list_xattr
    function in hw/9pfs/9p-xattr.c allowed local guest OS
    privileged users to cause a denial of service (memory
    consumption) via vectors involving the orig_value
    variable (bsc#1035950)

  - CVE-2017-7471: The VirtFS host directory sharing via
    Plan 9 File System(9pfs) support was vulnerable to an
    improper access control issue which allowed a privileged
    user inside guest to access host file system beyond the
    shared folder and potentially escalating their
    privileges on a host (bsc#1034866)

  - CVE-2016-6834: A infinite loop during packet
    fragmentation in the VMWARE VMXNET3 NIC device support
    allowed privileged user inside guest to crash the Qemu
    instance resulting in DoS (bsc#994418)

  - CVE-2016-6835: Buffer overflow in the VMWARE VMXNET3 NIC
    device support, causing an OOB read access (bsc#994605)

  - CVE-2017-5715: QEMU was updated to allow passing through
    new MSR and CPUID flags from the host VM to the CPU, to
    allow enabling/disabling branch prediction features in
    the Intel CPU. (bsc#1068032) Also a security fix has
    been applied :

  - CVE-2017-2633: Fix various out of bounds access issues
    in the QEMU vnc infrastructure (bsc#1026612)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Kernel-based Virtual Machine (KVM) is a full virtualization solution
for Linux on a variety of architectures. The qemu-kvm package provides
the user-space component for running virtual machines that use KVM.

Security Fix(es) :

* A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA
emulator's VNC display driver support; the issue could occur when a
VNC client attempted to update its display after a VGA operation is
performed by a guest. A privileged user/process inside a guest could
use this flaw to crash the QEMU process or, potentially, execute
arbitrary code on the host with privileges of the QEMU process.
(CVE-2016-9603)

* An out-of-bounds r/w access issue was found in QEMU's Cirrus CLGD
54xx VGA Emulator support. The vulnerability could occur while copying
VGA data via various bitblt functions. A privileged user inside a
guest could use this flaw to crash the QEMU process or, potentially,
execute arbitrary code on the host with privileges of the QEMU
process. (CVE-2017-7980)

* An out-of-bounds memory access issue was found in QEMU's VNC display
driver support. The vulnerability could occur while refreshing the VNC
display surface area in the 'vnc_refresh_server_surface'. A
user/process inside a guest could use this flaw to crash the QEMU
process, resulting in a denial of service. (CVE-2017-2633)

* An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx
VGA Emulator support. The vulnerability could occur while copying VGA
data using bitblt functions (for example,
cirrus_bitblt_rop_fwd_transp_). A privileged user inside a guest could
use this flaw to crash the QEMU process, resulting in denial of
service. (CVE-2017-7718)
