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

  - In QEMU through 5.0.0, an assertion failure can occur
    in the network packet processing. This issue affects
    the e1000e and vmxnet3 network devices. A malicious
    guest user/process could use this flaw to abort the
    QEMU process on the host, resulting in a denial of
    service condition in net_tx_pkt_add_raw_fragment in
    hw/net/net_tx_pkt.c.(CVE-2020-16092)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
