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 :

  - qemu-kvm is an open source virtualizer that provides     hardware emulation for the KVM hypervisor. qemu-kvm     acts as a virtual machine monitor together with the KVM     kernel modules, and emulates the hardware for a full     system such as a PC and its assocated peripherals. As     qemu-kvm requires no host kernel patches to run, it is     safe and easy to use.

It hits an     assertion that implies that the size of successful DMA     transfers there must be a multiple of 512 (the size of     a sector). NOTE: a member of the QEMU security team     disputes the significance of this issue because a     'privileged guest user has many ways to cause similar     DoS effect, without triggering this     assert.'(CVE-2019-20175)Race condition in the     v9fs_xattrwalk function in hw/9pfs/9p.c in QEMU (aka     Quick Emulator) allows local guest OS users to obtain     sensitive information from host heap memory via vectors     related to reading extended     attributes.(cve-2017-15038)Memory leak in the     megasas_handle_dcmd function in hw/scsi/megasas.c in     QEMU (aka Quick Emulator) allows local guest OS     privileged users to cause a denial of service (host     memory consumption) via MegaRAID Firmware Interface     (MFI) commands with the sglist size set to a value over     2 Gb.(cve-2017-5856)QEMU (aka Quick Emulator), when     built with the e1000e NIC emulation support, allows     local guest OS privileged users to cause a denial of     service (infinite loop) via vectors related to setting     the initial receive / transmit descriptor head     (TDH/RDH) outside the allocated descriptor     buffer.(cve-2017-9310)QEMU (aka Quick Emulator), when     built with MegaRAID SAS 8708EM2 Host Bus Adapter     emulation support, allows local guest OS privileged     users to cause a denial of service (NULL pointer     dereference and QEMU process crash) via vectors     involving megasas command processing.(cve-2017-9503)The     dhcp_decode function in slirp/bootp.c in QEMU (aka     Quick Emulator) allows local guest OS users to cause a     denial of service (out-of-bounds read and QEMU process     crash) via a crafted DHCP options     string.(CVE-2017-11434)Memory leak in the     v9fs_list_xattr function in hw/9pfs/9p-xattr.c in QEMU     (aka Quick Emulator) allows local guest OS privileged     users to cause a denial of service (memory consumption)     via vectors involving the orig_value     variable.(CVE-2017-8086)m_cat in slirp/mbuf.c in Qemu     has a heap-based buffer overflow via incoming     fragmented datagrams.(CVE-2018-11806)In QEMU 3.1.0,     load_device_tree in device_tree.c calls the deprecated     load_image function, which has a buffer overflow     risk.(CVE-2018-20815)The pnv_lpc_do_eccb function in     hw/ppc/pnv_lpc.c in Qemu before 3.1 allows     out-of-bounds write or read access to PowerNV     memory.(cve-2018-18954)qemu_deliver_packet_iov in     net/net.c in Qemu accepts packet sizes greater than     INT_MAX, which allows attackers to cause a denial of     service or possibly have unspecified other     impact.(CVE-2018-17963)Qemu has a Buffer Overflow in     pcnet_receive in hw/net/pcnet.c because an incorrect     integer data type is used.(CVE-2018-17962)Qemu has a     Buffer Overflow in rtl8139_do_receive in     hw/net/rtl8139.c because an incorrect integer data type     is used.(CVE-2018-17958)qemu-seccomp.c in QEMU might     allow local OS guest users to cause a denial of service     (guest crash) by leveraging mishandling of the seccomp     policy for threads other than the main     thread.(CVE-2018-15746)In QEMU 1:4.1-1,     1:2.1+dfsg-12+deb8u6, 1:2.8+dfsg-6+deb9u8,     1:3.1+dfsg-8~deb10u1, 1:3.1+dfsg-8+deb10u2, and     1:2.1+dfsg-12+deb8u12 (fixed), when executing script in     lsi_execute_script(), the LSI scsi adapter emulator     advances 's->dsp' index to read next opcode.
