There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Quick emulator (QEMU) before 2.8 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)

  - Memory leak in hw/net/eepro100.c in QEMU (aka Quick Emulator) allows local guest OS administrators to
    cause a denial of service (memory consumption and QEMU process crash) by repeatedly unplugging an i8255x
    (PRO100) NIC device. (CVE-2016-9101)

  - Memory leak in the v9fs_xattrcreate function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local
    guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) via a
    large number of Txattrcreate messages with the same fid number. (CVE-2016-9102)

  - The v9fs_xattrcreate function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local guest OS
    administrators to obtain sensitive host heap memory information by reading xattribute values before
    writing to them. (CVE-2016-9103)

  - Multiple integer overflows in the (1) v9fs_xattr_read and (2) v9fs_xattr_write functions in hw/9pfs/9p.c
    in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU
    process crash) via a crafted offset, which triggers an out-of-bounds access. (CVE-2016-9104)

  - Memory leak in the virtio_gpu_resource_create_2d function in hw/display/virtio-gpu.c in QEMU (aka Quick
    Emulator) allows local guest OS administrators to cause a denial of service (memory consumption) via a
    large number of VIRTIO_GPU_CMD_RESOURCE_CREATE_2D commands. (CVE-2016-7994)

  - Memory leak in the ehci_process_itd function in hw/usb/hcd-ehci.c in QEMU (aka Quick Emulator) allows
    local guest OS administrators to cause a denial of service (memory consumption) via a large number of
    crafted buffer page select (PG) indexes. (CVE-2016-7995)

  - The xhci_ring_fetch function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator) allows local guest OS
    administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging failure
    to limit the number of link Transfer Request Blocks (TRB) to process. (CVE-2016-8576)

  - Memory leak in the v9fs_read function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local guest OS
    administrators to cause a denial of service (memory consumption) via vectors related to an I/O read
    operation. (CVE-2016-8577)

The remote host is affected by the vulnerability described in GLSA-201702-28 (QEMU: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in QEMU. Please review the       CVE identifiers referenced below for details.
  Impact :

    A local attacker could potentially execute arbitrary code with       privileges of QEMU process on the host, gain privileges on the host       system, cause a Denial of Service condition, or obtain sensitive       information.
  Workaround :

    There is no known workaround at this time.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2019-4713 advisory.
