"According to the versions of the spdk package installed, the EulerOS
Virtualization for ARM 64 installation on the remote host is affected
by the following vulnerabilities :

  - A flaw was found in dpdk in versions before 18.11.10
    and before 19.11.5. A complete lack of validation of
    attacker-controlled parameters can lead to a buffer
    over read. The results of the over read are then
    written back to the guest virtual machine memory. This
    vulnerability can be used by an attacker in a virtual
    machine to read significant amounts of host memory. The
    highest threat from this vulnerability is to data
    confidentiality and system
    availability.(CVE-2020-14377)

  - A flaw was found in dpdk in versions before 18.11.10
    and before 19.11.5. A lack of bounds checking when
    copying iv_data from the VM guest memory into host
    memory can lead to a large buffer overflow. The highest
    threat from this vulnerability is to data
    confidentiality and integrity as well as system
    availability.(CVE-2020-14376)

  - A flaw was found in dpdk in versions before 18.11.10
    and before 19.11.5. A flawed bounds checking in the
    copy_data function leads to a buffer overflow allowing
    an attacker in a virtual machine to write arbitrary
    data to any address in the vhost_crypto application.
    The highest threat from this vulnerability is to data
    confidentiality and integrity as well as system
    availability.(CVE-2020-14374)

  - A flaw was found in dpdk in versions before 18.11.10
    and before 19.11.5. Virtio ring descriptors, and the
    data they describe are in a region of memory accessible
    by from both the virtual machine and the host. An
    attacker in a VM can change the contents of the memory
    after vhost_crypto has validated it. The highest threat
    from this vulnerability is to data confidentiality and
    integrity as well as system
    availability.CVE-2020-14375)
