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

  - An integer overflow issue was found in the NE200 NIC     emulation. It could occur while receiving packets from     the network, if the size value was greater than     INT_MAX. Such overflow would lead to stack buffer     overflow issue. A user inside guest could use this flaw     to crash the QEMU process, resulting in DoS scenario.
    (CVE-2018-10839)

  - qmp_guest_file_read in qga/commands-posix.c and     qga/commands-win32.c in qemu-ga (aka QEMU Guest Agent)     in QEMU 2.12.50 has an integer overflow causing a     g_malloc0() call to trigger a segmentation fault when     trying to allocate a large memory chunk. The     vulnerability can be exploited by sending a crafted QMP     command (including guest-file-read with a large count     value) to the agent via the listening     socket.(CVE-2018-12617)

  - Qemu before version 2.9 is vulnerable to an improper     link following when built with the VirtFS. A privileged     user inside guest could use this flaw to access host     file system beyond the shared folder and potentially     escalating their privileges on a host. (CVE-2016-9602)

  - Quick Emulator (QEMU), compiled with the PC System     Emulator with multiboot feature support, is vulnerable     to an OOB r/w memory access issue. The issue could     occur while loading a kernel image during the guest     boot, if mh_load_end_addr address is greater than the     mh_bss_end_addr address. A user or process could use     this flaw to potentially achieve arbitrary code     execution on a host.(CVE-2018-7550)

  - An out-of-bounds read access issue was found in the VGA     display emulator built into the Quick emulator (QEMU).
    It could occur while reading VGA memory to update     graphics display. A privileged user/process inside     guest could use this flaw to crash the QEMU process on     the host resulting in denial of service     situation.(CVE-2017-13672)

  - An assert failure issue was found in the VGA display     emulator built into the Quick emulator (QEMU). It could     occur while updating graphics display, due to     miscalculating region for dirty bitmap snapshot in     split screen mode. A privileged user/process inside     guest could use this flaw to crash the QEMU process on     the host resulting in denial of service.
    (CVE-2017-13673)

  - The Network Block Device (NBD) server in Quick Emulator     (QEMU), is vulnerable to a denial of service issue. It     could occur if a client sent large option requests,     making the server waste CPU time on reading up to 4GB     per request. A client could use this flaw to keep the     NBD server from serving other requests, resulting in     DoS.(CVE-2017-15119)

  - QEMU (aka Quick Emulator) before 2.9.0, when built with     the USB OHCI Emulation support, allows local guest OS     users to cause a denial of service (infinite loop) by     leveraging an incorrect return value, a different     vulnerability than CVE-2017-6505.(CVE-2017-9330)

  - 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)

  - VNC server implementation in Quick Emulator (QEMU) was     found to be vulnerable to an unbounded memory     allocation issue, as it did not throttle the     framebuffer updates sent to its client. If the client     did not consume these updates, VNC server allocates     growing memory to hold onto this data. A malicious     remote VNC client could use this flaw to cause DoS to     the server host.(CVE-2017-15124)

  - A memory leakage issue was found in the I/O channels     websockets implementation of the Quick Emulator (QEMU).
    It could occur while sending screen updates to a     client, which is slow to read and process them further.
    A privileged guest user could use this flaw to cause a     denial of service on the host and/or potentially crash     the QEMU process instance on the host.(CVE-2017-15268)

  - Quick Emulator (QEMU), compiled with the PC System     Emulator with multiboot feature support, is vulnerable     to an OOB r/w memory access issue. The issue could     occur due to an integer overflow while loading a kernel     image during a guest boot. A user or process could use     this flaw to potentially achieve arbitrary code     execution on a host.(CVE-2017-14167)

  - 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)

  - 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)

  - ** DISPUTED ** The disas_insn function in     target/i386/translate.c in QEMU before 2.9.0, when TCG     mode without hardware acceleration is used, does not     limit the instruction size, which allows local users to     gain privileges by creating a modified basic block that     injects code into a setuid program, as demonstrated by     procmail. NOTE: the vendor has stated 'this bug does     not violate any security guarantees QEMU     makes.'(CVE-2017-8284)

  - Memory leak in the keyboard input event handlers     support in QEMU (aka Quick Emulator) allows local guest     OS privileged users to cause a denial of service (host     memory consumption) by rapidly generating large     keyboard events.(CVE-2017-8379)

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - QEMU (aka Quick Emulator), when built with the VGA display emulator support, allows local guest OS     privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) via vectors     involving display update. (CVE-2017-13672)

Note that Nessus relies on the presence of the package as reported by the vendor.
