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

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc.Security Fix(es):A flaw named FragmentSmack     was found in the way the Linux kernel handled     reassembly of fragmented IPv4 and IPv6 packets. A     remote attacker could use this flaw to trigger time and     calculation expensive fragment reassembly algorithm by     sending specially crafted packets which could lead to a     CPU saturation and hence a denial of service on the     system.(CVE-2018-5391)Multiple out-of-bounds write     flaws were found in the way the Cherry Cymotion     keyboard driver, KYE/Genius device drivers, Logitech     device drivers, Monterey Genius KB29E keyboard driver,     Petalynx Maxter remote control driver, and Sunplus     wireless desktop driver handled HID reports with an     invalid report descriptor size. An attacker with     physical access to the system could use either of these     flaws to write data past an allocated memory     buffer.(CVE-2014-3184)The __get_data_block function in     fs/f2fs/data.c in the Linux kernel before 4.11 allows     local users to cause a denial of service (integer     overflow and loop) via crafted use of the open and     fallocate system calls with an FS_IOC_FIEMAP     ioctl.(CVE-2017-18257)netetfilter/xt_osf.c in the Linux     kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for add_callback and     remove_callback operations. This allows local users to     bypass intended access restrictions because the     xt_osf_fingers data structure is shared across all     network namespaces.(CVE-2017-17450)A denial of service     flaw was discovered in the Linux kernel, where a race     condition caused a NULL pointer dereference in the RDS     socket-creation code. A local attacker could use this     flaw to create a situation in which a NULL pointer     crashed the kernel.(CVE-2015-7990)An issue was     discovered in the Linux kernel before 4.19.9. The USB     subsystem mishandles size checks during the reading of     an extra descriptor, related to
    __usb_get_extra_descriptor in     drivers/usb/core/usb.c.(CVE-2018-20169)mm/memory.c in     the Linux kernel before 4.1.4 mishandles anonymous     pages, which allows local users to gain privileges or     cause a denial of service (page tainting) via a crafted     application that triggers writing to page     zero.(CVE-2015-3288)The ovl_setattr function in     fs/overlayfs/inode.c in the Linux kernel through 4.3.3     attempts to merge distinct setattr operations, which     allows local users to bypass intended access     restrictions and modify the attributes of arbitrary     overlay files via a crafted     application.(CVE-2015-8660)A flaw was found in the     Linux kernel where a local user with a shell account     can abuse the userfaultfd syscall when using hugetlbfs.
    A missing size check in hugetlb_mcopy_atomic_pte could     create an invalid inode variable, leading to a kernel     panic.(CVE-2017-15128)An integer overflow flaw was     found in the way the lzo1x_decompress_safe() function     of the Linux kernel's LZO implementation processed     Literal Runs. A local attacker could, in extremely rare     cases, use this flaw to crash the system or,     potentially, escalate their privileges on the     system.(CVE-2014-4608)It was found that Linux kernel's     ptrace subsystem did not properly sanitize the     address-space-control bits when the program-status word     (PSW) was being set. On IBM S/390 systems, a local,     unprivileged user could use this flaw to set     address-space-control bits to the kernel space, and     thus gain read and write access to kernel     memory.(CVE-2014-3534)A use-after-free flaw was found     in the Linux kernel's file system encryption     implementation. A local user could revoke keyring keys     being used for ext4, f2fs, or ubifs encryption, causing     a denial of service on the system.(CVE-2017-7374)The     usbip_recv_xbuff function in     drivers/usb/usbip/usbip_common.c in the Linux kernel     before 4.5.3 allows remote attackers to cause a denial     of service (out-of-bounds write) or possibly have     unspecified other impact via a crafted length value in     a USB/IP packet.(CVE-2016-3955)A flaw was found in the     patches used to fix the 'dirtycow' vulnerability     (CVE-2016-5195). An attacker, able to run local code,     can exploit a race condition in transparent huge pages     to modify usually read-only huge     pages.(CVE-2017-1000405)The aio_mount function in     fs/aio.c in the Linux kernel does not properly restrict     execute access, which makes it easier for local users     to bypass intended SELinux W^X policy     restrictions.(CVE-2016-10044)The Serial Attached SCSI     (SAS) implementation in the Linux kernel mishandles a     mutex within libsas. This allows local users to cause a     denial of service (deadlock) by triggering certain     error-handling code.(CVE-2017-18232)A use-after-free     vulnerability was found in tcp_xmit_retransmit_queue     and other tcp_* functions. This condition could allow     an attacker to send an incorrect selective     acknowledgment to existing connections, possibly     resetting a connection.(CVE-2016-6828)The instruction     decoder in arch/x86/kvm/emulate.c in the KVM subsystem     in the Linux kernel before 3.18-rc2 does not properly     handle invalid instructions, which allows guest OS     users to cause a denial of service (NULL pointer     dereference and host OS crash) via a crafted     application that triggers (1) an improperly fetched     instruction or (2) an instruction that occupies too     many bytes. NOTE: this vulnerability exists because of     an incomplete fix for CVE-2014-8480.(CVE-2014-8481)The     snd_compress_check_input function in     sound/core/compress_offload.c in the ALSA subsystem in     the Linux kernel before 3.17 does not properly check     for an integer overflow, which allows local users to     cause a denial of service (insufficient memory     allocation) or possibly have unspecified other impact     via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl     call.(CVE-2014-9904)The resv_map_release function in     mm/hugetlb.c in the Linux kernel, through 4.15.7,     allows local users to cause a denial of service (BUG)     via a crafted application that makes mmap system calls     and has a large pgoff argument to the remap_file_pages     system call.(CVE-2018-7740)

  - Improved support for Hyper-V

  - Support for Matrox G200eH3

  - Support for tcp_westwood The following security bugs     were fixed :

  - CVE-2017-2671: The ping_unhash function in     net/ipv4/ping.c in the Linux kernel was too late in     obtaining a certain lock and consequently could not     ensure that disconnect function calls are safe, which     allowed local users to cause a denial of service (panic)     by leveraging access to the protocol value of     IPPROTO_ICMP in a socket system call (bnc#1031003).

  - CVE-2017-7308: The packet_set_ring function in     net/packet/af_packet.c in the Linux kernel did not     properly validate certain block-size data, which allowed     local users to cause a denial of service (overflow) or     possibly have unspecified other impact via crafted     system calls (bnc#1031579).

  - CVE-2017-7294: The vmw_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not validate addition of certain levels data,     which allowed local users to trigger an integer overflow     and out-of-bounds write, and cause a denial of service     (system hang or crash) or possibly gain privileges, via     a crafted ioctl call for a /dev/dri/renderD* device     (bnc#1031440).

  - CVE-2017-7261: The vmw_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not check for a zero value of certain levels     data, which allowed local users to cause a denial of     service (ZERO_SIZE_PTR dereference, and GPF and possibly     panic) via a crafted ioctl call for a /dev/dri/renderD*     device (bnc#1031052).

  - CVE-2017-7187: The sg_ioctl function in     drivers/scsi/sg.c in the Linux kernel allowed local     users to cause a denial of service (stack-based buffer     overflow) or possibly have unspecified other impact via     a large command size in an SG_NEXT_CMD_LEN ioctl call,     leading to out-of-bounds write access in the sg_write     function (bnc#1030213).

  - CVE-2017-7374: Use-after-free vulnerability in     fs/crypto/ in the Linux kernel allowed local users to     cause a denial of service (NULL pointer dereference) or     possibly gain privileges by revoking keyring keys being     used for ext4, f2fs, or ubifs encryption, causing     cryptographic transform objects to be freed prematurely     (bnc#1032006).

  - CVE-2016-10200: Race condition in the L2TPv3 IP     Encapsulation feature in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (use-after-free) by making multiple bind system calls     without properly ascertaining whether a socket has the     SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and     net/l2tp/l2tp_ip6.c (bnc#1028415).

  - CVE-2017-6345: The LLC subsystem in the Linux kernel did     not ensure that a certain destructor exists in required     circumstances, which allowed local users to cause a     denial of service (BUG_ON) or possibly have unspecified     other impact via crafted system calls (bnc#1027190).

  - CVE-2017-6346: Race condition in net/packet/af_packet.c     in the Linux kernel allowed local users to cause a     denial of service (use-after-free) or possibly have     unspecified other impact via a multithreaded application     that made PACKET_FANOUT setsockopt system calls     (bnc#1027189).

  - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did     not properly restrict association peel-off operations     during certain wait states, which allowed local users to     cause a denial of service (invalid unlock and double     free) via a multithreaded application. NOTE: this     vulnerability exists because of an incorrect fix for     CVE-2017-5986 (bnc#1027066).

  - CVE-2017-6214: The tcp_splice_read function in     net/ipv4/tcp.c in the Linux kernel allowed remote     attackers to cause a denial of service (infinite loop     and soft lockup) via vectors involving a TCP packet with     the URG flag (bnc#1026722).

  - CVE-2016-2117: The atl2_probe function in     drivers/net/ethernet/atheros/atlx/atl2.c in the Linux     kernel incorrectly enables scatter/gather I/O, which     allowed remote attackers to obtain sensitive information     from kernel memory by reading packet data (bnc#968697).

  - CVE-2017-6347: The ip_cmsg_recv_checksum function in     net/ipv4/ip_sockglue.c in the Linux kernel had incorrect     expectations about skb data layout, which allowed local     users to cause a denial of service (buffer over-read) or     possibly have unspecified other impact via crafted     system calls, as demonstrated by use of the MSG_MORE     flag in conjunction with loopback UDP transmission     (bnc#1027179).

  - CVE-2016-9191: The cgroup offline implementation in the     Linux kernel mishandled certain drain operations, which     allowed local users to cause a denial of service (system     hang) by leveraging access to a container environment     for executing a crafted application (bnc#1008842).

  - CVE-2017-2596: The nested_vmx_check_vmptr function in     arch/x86/kvm/vmx.c in the Linux kernel improperly     emulated the VMXON instruction, which allowed KVM L1     guest OS users to cause a denial of service (host OS     memory consumption) by leveraging the mishandling of     page references (bnc#1022785).

  - CVE-2017-6074: The dccp_rcv_state_process function in     net/dccp/input.c in the Linux kernel mishandled     DCCP_PKT_REQUEST packet data structures in the LISTEN     state, which allowed local users to obtain root     privileges or cause a denial of service (double free)     via an application that made an IPV6_RECVPKTINFO     setsockopt system call (bnc#1026024).

The update package also includes non-security fixes. See advisory for details.

  - CVE-2016-4997: The compat IPT_SO_SET_REPLACE and     IP6T_SO_SET_REPLACE setsockopt implementations in the     netfilter subsystem in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (memory corruption) by leveraging in-container root     access to provide a crafted offset value that triggers     an unintended decrement (bnc#986362).

  - CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt     implementation in the netfilter subsystem in the Linux     kernel allowed local users to cause a denial of service     (out-of-bounds read) or possibly obtain sensitive     information from kernel heap memory by leveraging     in-container root access to provide a crafted offset     value that leads to crossing a ruleset blob boundary     (bnc#986365).

  - CVE-2017-7616: Incorrect error handling in the     set_mempolicy and mbind compat syscalls in     mm/mempolicy.c in the Linux kernel allowed local users     to obtain sensitive information from uninitialized stack     data by triggering failure of a certain bitmap operation     (bnc#1033336).
