"An out-of-bounds read access issue was found in the VGA display
emulator built into the Quick emulator (QEMU). It could occur while
reading VGA memory to update graphics display. A privileged
user/process inside guest could use this flaw to crash the QEMU
process on the host resulting in denial of service
situation.(CVE-2017-13672)

A memory leakage issue was found in the I/O channels websockets
implementation of the Quick Emulator (QEMU). It could occur while
sending screen updates to a client, which is slow to read and process
them further. A privileged guest user could use this flaw to cause a
denial of service on the host and/or potentially crash the QEMU
process instance on the host.(CVE-2017-15268)

A use-after-free issue was found in the Slirp networking
implementation of the Quick emulator (QEMU). It occurs when a Socket
referenced from multiple packets is freed while responding to a
message. A user/process could use this flaw to crash the QEMU process
on the host resulting in denial of service.(CVE-2017-13711 )

Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA
Emulator support, allows local guest OS privileged users to cause a
denial of service (out-of-bounds access and QEMU process crash) by
leveraging incorrect region calculation when updating VGA
display.(CVE-2018-7858)

VNC server implementation in Quick Emulator (QEMU) was found to be
vulnerable to an unbounded memory allocation issue, as it did not
throttle the framebuffer updates sent to its client. If the client did
not consume these updates, VNC server allocates growing memory to hold
onto this data. A malicious remote VNC client could use this flaw to
cause DoS to the server host.(CVE-2017-15124)

An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of Load & Store
instructions (a commonly used performance optimization). It relies on
the presence of a precisely-defined instruction sequence in the
privileged code as well as the fact that memory read from address to
which a recent memory write has occurred may see an older value and
subsequently cause an update into the microprocessor's data cache even
for speculatively executed instructions that never actually commit
(retire). As a result, an unprivileged attacker could use this flaw to
read privileged memory by conducting targeted cache side-channel
attacks.(CVE-2018-3639)

An out-of-bounds read access issue was found in the VGA emulator of
QEMU. It could occur in vga_draw_text routine, while updating display
area for a vnc client. A privileged user inside a guest could use this
flaw to crash the QEMU process resulting in DoS.(CVE-2018-5683)"

"According to the versions of the qemu-kvm packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - An integer overflow issue was found in the NE200 NIC
    emulation. It could occur while receiving packets from
    the network, if the size value was greater than
    INT_MAX. Such overflow would lead to stack buffer
    overflow issue. A user inside guest could use this flaw
    to crash the QEMU process, resulting in DoS scenario.
    (CVE-2018-10839)

  - qmp_guest_file_read in qga/commands-posix.c and
    qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent)
    in QEMU 2.12.50 has an integer overflow causing a
    g_malloc0() call to trigger a segmentation fault when
    trying to allocate a large memory chunk. The
    vulnerability can be exploited by sending a crafted QMP
    command (including guest-file-read with a large count
    value) to the agent via the listening
    socket.(CVE-2018-12617)

  - Qemu before version 2.9 is vulnerable to an improper
    link following when built with the VirtFS. A privileged
    user inside guest could use this flaw to access host
    file system beyond the shared folder and potentially
    escalating their privileges on a host. (CVE-2016-9602)

  - Quick Emulator (QEMU), compiled with the PC System
    Emulator with multiboot feature support, is vulnerable
    to an OOB r/w memory access issue. The issue could
    occur while loading a kernel image during the guest
    boot, if mh_load_end_addr address is greater than the
    mh_bss_end_addr address. A user or process could use
    this flaw to potentially achieve arbitrary code
    execution on a host.(CVE-2018-7550)

  - An out-of-bounds read access issue was found in the VGA
    display emulator built into the Quick emulator (QEMU).
    It could occur while reading VGA memory to update
    graphics display. A privileged user/process inside
    guest could use this flaw to crash the QEMU process on
    the host resulting in denial of service
    situation.(CVE-2017-13672)

  - An assert failure issue was found in the VGA display
    emulator built into the Quick emulator (QEMU). It could
    occur while updating graphics display, due to
    miscalculating region for dirty bitmap snapshot in
    split screen mode. A privileged user/process inside
    guest could use this flaw to crash the QEMU process on
    the host resulting in denial of service.
    (CVE-2017-13673)

  - The Network Block Device (NBD) server in Quick Emulator
    (QEMU), is vulnerable to a denial of service issue. It
    could occur if a client sent large option requests,
    making the server waste CPU time on reading up to 4GB
    per request. A client could use this flaw to keep the
    NBD server from serving other requests, resulting in
    DoS.(CVE-2017-15119)

  - QEMU (aka Quick Emulator) before 2.9.0, when built with
    the USB OHCI Emulation support, allows local guest OS
    users to cause a denial of service (infinite loop) by
    leveraging an incorrect return value, a different
    vulnerability than CVE-2017-6505.(CVE-2017-9330)

  - Integer overflow in the macro ROUND_UP (n, d) in Quick
    Emulator (Qemu) allows a user to cause a denial of
    service (Qemu process crash). (CVE-2017-18043)

  - VNC server implementation in Quick Emulator (QEMU) was
    found to be vulnerable to an unbounded memory
    allocation issue, as it did not throttle the
    framebuffer updates sent to its client. If the client
    did not consume these updates, VNC server allocates
    growing memory to hold onto this data. A malicious
    remote VNC client could use this flaw to cause DoS to
    the server host.(CVE-2017-15124)

  - A memory leakage issue was found in the I/O channels
    websockets implementation of the Quick Emulator (QEMU).
    It could occur while sending screen updates to a
    client, which is slow to read and process them further.
    A privileged guest user could use this flaw to cause a
    denial of service on the host and/or potentially crash
    the QEMU process instance on the host.(CVE-2017-15268)

  - Quick Emulator (QEMU), compiled with the PC System
    Emulator with multiboot feature support, is vulnerable
    to an OOB r/w memory access issue. The issue could
    occur due to an integer overflow while loading a kernel
    image during a guest boot. A user or process could use
    this flaw to potentially achieve arbitrary code
    execution on a host.(CVE-2017-14167)

  - Memory leak in QEMU (aka Quick Emulator), when built
    with IDE AHCI Emulation support, allows local guest OS
    privileged users to cause a denial of service (memory
    consumption) by repeatedly hot-unplugging the AHCI
    device.(CVE-2017-9373)

  - Memory leak in the serial_exit_core function in
    hw/char/serial.c in QEMU (aka Quick Emulator) allows
    local guest OS privileged users to cause a denial of
    service (host memory consumption and QEMU process
    crash) via a large number of device unplug
    operations.(CVE-2017-5579)

  - ** DISPUTED ** The disas_insn function in
    target/i386/translate.c in QEMU before 2.9.0, when TCG
    mode without hardware acceleration is used, does not
    limit the instruction size, which allows local users to
    gain privileges by creating a modified basic block that
    injects code into a setuid program, as demonstrated by
    procmail. NOTE: the vendor has stated 'this bug does
    not violate any security guarantees QEMU
    makes.'(CVE-2017-8284)

  - Memory leak in the keyboard input event handlers
    support in QEMU (aka Quick Emulator) allows local guest
    OS privileged users to cause a denial of service (host
    memory consumption) by rapidly generating large
    keyboard events.(CVE-2017-8379)

"This update for qemu fixes the following issues: This update has the
next round of Spectre v2 related patches, which now integrate with
corresponding changes in libvirt. (CVE-2017-5715 bsc#1068032) The
January 2018 release of qemu initially addressed the Spectre v2
vulnerability for KVM guests by exposing the spec-ctrl feature for all
x86 vcpu types, which was the quick and dirty approach, but not the
proper solution. We replaced our initial patch by the patches from
upstream. This update defines spec_ctrl and ibpb cpu feature flags as
well as new cpu models which are clones of existing models with either
-IBRS or -IBPB added to the end of the model name. These new vcpu
models explicitly include the new feature(s), whereas the feature
flags can be added to the cpu parameter as with other features. In
short, for continued Spectre v2 protection, ensure that either the
appropriate cpu feature flag is added to the QEMU command-line, or one
of the new cpu models is used. Although migration from older versions
is supported, the new cpu features won't be properly exposed to the
guest until it is restarted with the cpu features explicitly added. A
reboot is insufficient. A warning patch is added which attempts to
detect a migration from a qemu version which had the quick and dirty
fix (it only detects certain cases, but hopefully is helpful.) For
additional information on Spectre v2 as it relates to QEMU, see:
https://www.qemu.org/2018/02/14/qemu-2-11-1-and-spectre-update/ A
patch is added to continue to detect Spectre v2 mitigation features
(as shown by cpuid), and if found provide that feature to guests, even
if running on older KVM (kernel) versions which do not yet expose that
feature to QEMU. (bsc#1082276) These two patches will be removed when
we can reasonably assume everyone is running with the appropriate
updates. Also security fixes for the following CVE issues are 
included :

  - CVE-2017-15119: The Network Block Device (NBD) server in
    Quick Emulator (QEMU), was vulnerable to a denial of
    service issue. It could occur if a client sent large
    option requests, making the server waste CPU time on
    reading up to 4GB per request. A client could use this
    flaw to keep the NBD server from serving other requests,
    resulting in DoS. (bsc#1070144)

  - CVE-2017-15124: VNC server implementation in Quick
    Emulator (QEMU) was found to be vulnerable to an
    unbounded memory allocation issue, as it did not
    throttle the framebuffer updates sent to its client. If
    the client did not consume these updates, VNC server
    allocates growing memory to hold onto this data. A
    malicious remote VNC client could use this flaw to cause
    DoS to the server host. (bsc#1073489)

  - CVE-2017-16845: The PS2 driver in Qemu did not validate
    'rptr' and 'count' values during guest migration,
    leading to out-of-bounds access. (bsc#1068613)

  - CVE-2017-17381: The Virtio Vring implementation in QEMU
    allowed local OS guest users to cause a denial of
    service (divide-by-zero error and QEMU process crash) by
    unsetting vring alignment while updating Virtio rings.
    (bsc#1071228)

  - CVE-2017-18030: A problem in the Cirrus driver in Qemu
    allowed local OS guest privileged users to cause a
    denial of service (out-of-bounds array access and QEMU
    process crash) via vectors related to negative pitch.
    (bsc#1076179)

  - CVE-2017-18043: Integer overflow in the macro ROUND_UP
    (n, d) in Quick Emulator (Qemu) allowed a user to cause
    a denial of service (Qemu process crash). (bsc#1076775)

  - CVE-2018-5683: The VGA driver in Qemu allowed local OS
    guest privileged users to cause a denial of service
    (out-of-bounds read and QEMU process crash) by
    leveraging improper memory address validation.
    (bsc#1076114)

  - CVE-2018-7550: The multiboot functionality in Quick
    Emulator (aka QEMU) allowed local guest OS users to
    execute arbitrary code on the QEMU host via an
    out-of-bounds read or write memory access. (bsc#1083291)
    Also the following bugs were fixed :

  - Eliminate bogus use of CPUID_7_0_EDX_PRED_CMD which
    we've carried since the initial Spectre v2 patch was
    added. EDX bit 27 of CPUID Leaf 07H, Sub-leaf 0 provides
    status on STIBP, and not the PRED_CMD MSR. Exposing the
    STIBP CPUID feature bit to the guest is wrong in
    general, since the VM doesn't directly control the
    scheduling of physical hyperthreads. This is left
    strictly to the L0 hypervisor.

  - Spectre fixes for IBM Z series by providing more hw
    features to guests (bsc#1076814)

  - Pre-add group kvm for qemu-tools (bsc#1040202)

  - the qemu-tools package also needs a prerequire of group
    management tools, from the shadow package. (bsc#1085598)

"According to the versions of the qemu-kvm packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - QEMU (aka Quick Emulator), when built with the VGA
    display emulator support, allows local guest OS
    privileged users to cause a denial of service
    (out-of-bounds read and QEMU process crash) via vectors
    involving display update.(CVE-2017-13672)

  - Use-after-free vulnerability in the sofree function in
    slirp/socket.c in QEMU (aka Quick Emulator) allows
    attackers to cause a denial of service (QEMU instance
    crash) by leveraging failure to properly clear ifq_so
    from pending packets.(CVE-2017-13711)

  - VNC server implementation in Quick Emulator (QEMU)
    2.11.0 and older was found to be vulnerable to an
    unbounded memory allocation issue, as it did not
    throttle the framebuffer updates sent to its client. If
    the client did not consume these updates, VNC server
    allocates growing memory to hold onto this data. A
    malicious remote VNC client could use this flaw to
    cause DoS to the server host.(CVE-2017-15124)

  - Qemu through 2.10.0 allows remote attackers to cause a
    memory leak by triggering slow data-channel read
    operations, related to
    io/channel-websock.c.(CVE-2017-15268)

  - The vga_draw_text function in Qemu allows local OS
    guest privileged users to cause a denial of service
    (out-of-bounds read and QEMU process crash) by
    leveraging improper memory address
    validation.(CVE-2018-5683)

  - An industry-wide issue was found in the way many modern
    microprocessor designs have implemented speculative
    execution of Load i1/4+ Store instructions (a commonly
    used performance optimization). It relies on the
    presence of a precisely-defined instruction sequence in
    the privileged code as well as the fact that memory
    read from address to which a recent memory write has
    occurred may see an older value and subsequently cause
    an update into the microprocessor's data cache even for
    speculatively executed instructions that never actually
    commit (retire). As a result, an unprivileged attacker
    could use this flaw to read privileged memory by
    conducting targeted cache side-channel attacks.
    (CVE-2018-3639)

  - Quick Emulator (aka QEMU), when built with the Cirrus
    CLGD 54xx VGA Emulator support, allows local guest OS
    privileged users to cause a denial of service
    (out-of-bounds access and QEMU process crash) by
    leveraging incorrect region calculation when updating
    VGA display.(CVE-2018-7858)

description block directly from the EulerOS security advisory. Tenable
