"An update for kvm is now available for Red Hat Enterprise Linux 5.

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.

KVM (for Kernel-based Virtual Machine) is a full virtualization
solution for Linux on x86 hardware. Using KVM, one can run multiple
virtual machines running unmodified Linux or Windows images. Each
virtual machine has private virtualized hardware: a network card,
disk, graphics adapter, etc.

Security Fix(es) :

* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator
support is vulnerable to an out-of-bounds access issue. It could occur
while copying VGA data via bitblt copy in backward mode. A privileged
user inside a guest could use this flaw to crash the QEMU process
resulting in DoS or potentially execute arbitrary code on the host
with privileges of QEMU process on the host. (CVE-2017-2615)

* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA Emulator
support is vulnerable to an out-of-bounds access issue. The issue
could occur while copying VGA data in cirrus_bitblt_cputovideo. A
privileged user inside guest could use this flaw to crash the QEMU
process OR potentially execute arbitrary code on host with privileges
of the QEMU process. (CVE-2017-2620)

Red Hat would like to thank Wjjzhang (Tencent.com Inc.) and Li Qiang
(360.cn Inc.) for reporting CVE-2017-2615.

fixed :

  - CVE-2017-2620: In CIRRUS_BLTMODE_MEMSYSSRC mode the
    bitblit copy routine cirrus_bitblt_cputovideo failed to
    check the memory region, allowing for an out-of-bounds
    write that allows for privilege escalation (bsc#1024972)

  - CVE-2017-2615: An error in the bitblt copy operation
    could have allowed a malicious guest administrator to
    cause an out of bounds memory access, possibly leading
    to information disclosure or privilege escalation
    (bsc#1023004)

  - CVE-2017-5856: The MegaRAID SAS 8708EM2 Host Bus Adapter
    emulation support was vulnerable to a memory leakage
    issue allowing a privileged user to leak host memory
    resulting in DoS (bsc#1023053)

  - CVE-2016-9776: The ColdFire Fast Ethernet Controller
    emulator support was vulnerable to an infinite loop
    issue while receiving packets in 'mcf_fec_receive'. A
    privileged user/process inside guest could have used
    this issue to crash the Qemu process on the host leading
    to DoS (bsc#1013285)

  - CVE-2016-9911: The USB EHCI Emulation support was
    vulnerable to a memory leakage issue while processing
    packet data in 'ehci_init_transfer'. A guest
    user/process could have used this issue to leak host
    memory, resulting in DoS for the host (bsc#1014111)

  - CVE-2016-9907: The USB redirector usb-guest support was
    vulnerable to a memory leakage flaw when destroying the
    USB redirector in 'usbredir_handle_destroy'. A guest
    user/process could have used this issue to leak host
    memory, resulting in DoS for a host (bsc#1014109)

  - CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support
    was vulnerable to a divide by zero issue while copying
    VGA data. A privileged user inside guest could have used
    this flaw to crash the process instance on the host,
    resulting in DoS (bsc#1014702)

  - CVE-2016-9922: The Cirrus CLGD 54xx VGA Emulator support
    was vulnerable to a divide by zero issue while copying
    VGA data. A privileged user inside guest could have used
    this flaw to crash the process instance on the host,
    resulting in DoS (bsc#1014702)

  - CVE-2017-5667: The SDHCI device emulation support was
    vulnerable to an OOB heap access issue allowing a
    privileged user inside the guest to crash the Qemu
    process resulting in DoS or potentially execute
    arbitrary code with privileges of the Qemu process on
    the host (bsc#1022541)

  - CVE-2017-5898: The CCID Card device emulator support was
    vulnerable to an integer overflow allowing a privileged
    user inside the guest to crash the Qemu process
    resulting in DoS (bnc#1023907)

  - CVE-2016-10155: The i6300esb watchdog emulation support
    was vulnerable to a memory leakage issue allowing a
    privileged user inside the guest to leak memory on the
    host resulting in DoS (bnc#1021129)

"An update for qemu-kvm is now available for Red Hat Enterprise Linux
7.

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 packages provide
the user-space component for running virtual machines that use KVM.

Security Fix(es) :

* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator
support is vulnerable to an out-of-bounds access issue. It could occur
while copying VGA data via bitblt copy in backward mode. A privileged
user inside a guest could use this flaw to crash the QEMU process
resulting in DoS or potentially execute arbitrary code on the host
with privileges of QEMU process on the host. (CVE-2017-2615)

* Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA Emulator
support is vulnerable to an out-of-bounds access issue. The issue
could occur while copying VGA data in cirrus_bitblt_cputovideo. A
privileged user inside guest could use this flaw to crash the QEMU
process OR potentially execute arbitrary code on host with privileges
of the QEMU process. (CVE-2017-2620)

Red Hat would like to thank Wjjzhang (Tencent.com Inc.) and Li Qiang
(360.cn Inc.) for reporting CVE-2017-2615.

Bug Fix(es) :

* When using the virtio-blk driver on a guest virtual machine with no
space on the virtual hard drive, the guest terminated unexpectedly
with a 'block I/O error in device' message and the qemu-kvm process
exited with a segmentation fault. This update fixes how the
system_reset QEMU signal is handled in the above scenario. As a
result, if a guest crashes due to no space left on the device,
qemu-kvm continues running and the guest can be reset as expected.

resulting in DoS or potentially execute arbitrary code on the host
with privileges of Qemu process on the host. (CVE-2017-2615)

* An out-of-bounds read-access flaw was found in the QEMU emulator
built with IP checksum routines. The flaw could occur when computing a
TCP/UDP packet's checksum, because a QEMU function used the packet's
payload length without checking against the data buffer's size. A user
inside a guest could use this flaw to crash the QEMU process (denial
of service). (CVE-2016-2857)

Red Hat would like to thank Wjjzhang (Tencent.com Inc.) Li Qiang
(360.cn Inc.) for reporting CVE-2017-2615 and Ling Liu (Qihoo 360
Inc.) for reporting CVE-2016-2857.

This update also fixes the following bug :

* Previously, rebooting a guest virtual machine more than 128 times in
a short period of time caused the guest to shut down instead of
rebooting, because the virtqueue was not cleaned properly. This update
ensures that the virtqueue is cleaned more reliably, which prevents
the described problem from occurring. (BZ#1408389)

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."
