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)
