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

  - In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a
    heap-based buffer overflow.(CVE-2019-6778)

  - The MSI-X MMIO support in hw/pci/msix.c in QEMU (aka
    Quick Emulator) allows local guest OS privileged users
    to cause a denial of service (NULL pointer dereference
    and QEMU process crash) by leveraging failure to define
    the .write method.(CVE-2015-7549)

  - The ne2000_receive function in the NE2000 NIC emulation
    support (hw/net/ne2000.c) in QEMU before 2.5.1 allows
    local guest OS administrators to cause a denial of
    service (infinite loop and QEMU process crash) via
    crafted values for the PSTART and PSTOP registers,
    involving ring buffer control.(CVE-2016-2841)

  - Memory leak in QEMU (aka Quick Emulator), when built
    with USB EHCI Emulation support, allows local guest OS
    privileged users to cause a denial of service (memory
    consumption) by repeatedly hot-unplugging the
    device.(CVE-2017-9374)

  - 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)

  - 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)

  - The slirp_smb function in net/slirp.c in QEMU 2.3.0 and
    earlier creates temporary files with predictable names,
    which allows local users to cause a denial of service
    (instantiation failure) by creating /tmp/qemu-smb.*-*
    files before the program.(CVE-2015-4037)

  - The mcf_fec_do_tx function in hw/net/mcf_fec.c in QEMU
    (aka Quick Emulator) does not properly limit the buffer
    descriptor count when transmitting packets, which
    allows local guest OS administrators to cause a denial
    of service (infinite loop and QEMU process crash) via
    vectors involving a buffer descriptor with a length of
    0 and crafted values in bd.flags.(CVE-2016-7908)

  - hw/net/vmxnet3.c in QEMU 2.0.0-rc0, 1.7.1, and earlier
    allows local guest users to cause a denial of service
    or possibly execute arbitrary code via vectors related
    to (1) RX or (2) TX queue numbers or (3) interrupt
    indices. NOTE: some of these details are obtained from
    third party information.(CVE-2013-4544)

  - Multiple integer overflows in the USB Net device
    emulator (hw/usb/dev-network.c) in QEMU before 2.5.1
    allow local guest OS administrators to cause a denial
    of service (QEMU process crash) or obtain sensitive
    host memory information via a remote NDIS control
    message packet that is mishandled in the (1)
    rndis_query_response, (2) rndis_set_response, or (3)
    usb_net_handle_dataout function.(CVE-2016-2538)

  - Qemu emulator <= 3.0.0 built with the NE2000 NIC
    emulation support is vulnerable to an integer overflow,
    which could lead to buffer overflow issue. It could
    occur when receiving packets over the network. A user
    inside guest could use this flaw to crash the Qemu
    process resulting in DoS.(CVE-2018-10839)

  - 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)

  - tcp_emu in slirp/tcp_subr.c (aka slirp/src/tcp_subr.c)
    in QEMU 3.0.0 uses uninitialized data in an snprintf
    call, leading to Information disclosure.(CVE-2019-9824)

  - QEMU (aka Quick Emulator), when built with MegaRAID SAS
    8708EM2 Host Bus Adapter emulation support, allows
    local guest OS privileged users to cause a denial of
    service (NULL pointer dereference and QEMU process
    crash) via vectors involving megasas command
    processing.(CVE-2017-9503)

  - Buffer overflow in hw/ide/ahci.c in QEMU before 1.7.2
    allows remote attackers to cause a denial of service
    and possibly execute arbitrary code via vectors related
    to migrating ports.(CVE-2013-4526)

  - Buffer overflow in hw/ssi/pl022.c in QEMU before 1.7.2
    allows remote attackers to cause a denial of service or
    possibly execute arbitrary code via crafted
    tx_fifo_head and rx_fifo_head values in a savevm
    image.(CVE-2013-4530)

  - Multiple buffer overflows in the tsc210x_load function
    in hw/input/tsc210x.c in QEMU before 1.7.2 might allow
    remote attackers to execute arbitrary code via a
    crafted (1) precision, (2) nextprecision, (3) function,
    or (4) nextfunction value in a savevm
    image.(CVE-2013-4539)

  - Buffer overflow in scoop_gpio_handler_update in QEMU
    before 1.7.2 might allow remote attackers to execute
    arbitrary code via a large (1) prev_level, (2)
    gpio_level, or (3) gpio_dir value in a savevm
    image.(CVE-2013-4540)

  - The sdhci_sdma_transfer_multi_blocks function in
    hw/sd/sdhci.c in QEMU (aka Quick Emulator) allows local
    OS guest privileged users to cause a denial of service
    (infinite loop and QEMU process crash) via vectors
    involving the transfer mode register during multi block
    transfer.(CVE-2017-5987)

  - Microarchitectural Store Buffer Data Sampling (MSBDS):
    Store buffers on some microprocessors utilizing
    speculative execution may allow an authenticated user
    to potentially enable information disclosure via a side
    channel with local access. A list of impacted products

  - Microarchitectural Data Sampling Uncacheable Memory

    authenticated user to potentially enable information
    disclosure via a side channel with local access. A list

    ments/corporate-information/SA00233-microcode-update-gu
    idance_05132019.pdf(CVE-2019-11091)

  - interface_release_resource in hw/display/qxl.c in QEMU
    4.0.0 has a NULL pointer dereference.(CVE-2019-12155)

  - Heap-based buffer overflow in the .receive callback of
    xlnx.xps-ethernetlite in QEMU (aka Quick Emulator)
    allows attackers to execute arbitrary code on the QEMU
    host via a large ethlite packet.(CVE-2016-7161)

  - Heap-based buffer overflow in the ne2000_receive
    function in hw/net/ne2000.c in QEMU before 2.4.0.1
    allows guest OS users to cause a denial of service
    (instance crash) or possibly execute arbitrary code via
    vectors related to receiving packets.(CVE-2015-5279)

  - The sdhci_sdma_transfer_multi_blocks function in
    hw/sd/sdhci.c in QEMU (aka Quick Emulator) allows local
    guest OS privileged users to cause a denial of service
    (out-of-bounds heap access and crash) or execute
    arbitrary code on the QEMU host via vectors involving
