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. Security Fix(es):The     ohci_service_ed_list function in hw/usb/hcd-ohci.c in     QEMU (aka Quick Emulator) before 2.9.0 allows local     guest OS users to cause a denial of service (infinite     loop) via vectors involving the number of link endpoint     list descriptors, a different vulnerability than     CVE-2017-9330.(CVE-2017-6505)** DISPUTED ** QEMU 3.0.0     has an Integer Overflow because the qga/commands*.c     files do not check the length of the argument list or     the number of environment variables. NOTE: This has     been disputed as not exploitable.(CVE-2019-12247)**     DISPUTED ** An issue was discovered in ide_dma_cb() in     hw/ide/core.c in QEMU 2.4.0 through 4.2.0. The guest     system can crash the QEMU process in the host system     via a special SCSI_IOCTL_SEND_COMMAND. 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. This can     lead to an infinite loop if the next opcode is empty.
    Move the existing loop exit after 10k iterations so     that it covers no-op opcodes as     well.(CVE-2019-12068)qemu-bridge-helper.c in QEMU 4.0.0     does not ensure that a network interface name (obtained     from bridge.conf or a --br=bridge option) is limited to     the IFNAMSIZ size, which can lead to an ACL     bypass.(CVE-2019-13164)tcp_emu in slirp/tcp_subr.c (aka     slirp/src/tcp_subr.c) in QEMU 3.0.0 uses uninitialized     data in an snprintf call, leading to Information     disclosure.(CVE-2019-9824)interface_release_resource in     hw/display/qxl.c in QEMU 4.0.0 has a NULL pointer     dereference.(CVE-2019-12155)The Virtio Vring     implementation in QEMU allows local OS guest users to     cause a denial of service (divide-by-zero error and     QEMU process crash) by unsetting vring alignment while     updating Virtio     rings.(CVE-2017-17381)hw/display/cirrus_vga_rop.h in     QEMU (aka Quick Emulator) allows local guest OS     privileged users to cause a denial of service     (out-of-bounds read and QEMU process crash) via vectors     related to copying VGA data via the     cirrus_bitblt_rop_fwd_transp_ and     cirrus_bitblt_rop_fwd_ functions.(CVE-2017-7718)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)Quick Emulator (aka QEMU),     when built with the Cirrus CLGD 54xx VGA Emulator     support, allows local guest OS privileged users to     cause a denial of service (out-of-bounds access and     QEMU process crash) by leveraging incorrect region     calculation when updating VGA     display.(CVE-2018-7858)qemu-nbd in QEMU (aka Quick     Emulator) does not ignore SIGPIPE, which allows remote     attackers to cause a denial of service (daemon crash)     by disconnecting during a server-to-client reply     attempt.(CVE-2017-10664)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)QEMU     (aka Quick Emulator), when built with the IDE disk and     CD/DVD-ROM Emulator support, allows local guest OS     privileged users to cause a denial of service (NULL     pointer dereference and QEMU process crash) by flushing     an empty CDROM device drive.(CVE-2017-12809)
