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 :

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization(nVMX) feature     enabled(nested=1), is vulnerable to host memory leakage     issue. It could occur while emulating VMXON instruction     in 'handle_vmon'. An L1 guest user could use this flaw     to leak host memory potentially resulting in     DoS.(CVE-2017-2596i1/4%0

  - The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST     extension implementations in the sk_run_filter function     in net/core/filter.c in the Linux kernel through 3.14.3     do not check whether a certain length value is     sufficiently large, which allows local users to cause a     denial of service (integer underflow and system crash)     via crafted BPF instructions. NOTE: the affected code     was moved to the __skb_get_nlattr and
    __skb_get_nlattr_nest functions before the     vulnerability was announced.(CVE-2014-3144i1/4%0

  - A flaw was found in the Linux kernel when freeing pages     in hugetlbfs. This could trigger a local denial of     service by crashing the kernel.(CVE-2017-15127i1/4%0

  - An issue was discovered in the Linux kernel before 4.8.
    Incorrect access checking in overlayfs mounts could be     used by local attackers to modify or truncate files in     the underlying filesystem.(CVE-2018-16597i1/4%0

  - Memory leak in the cuse_channel_release function in     fs/fuse/cuse.c in the Linux kernel before 4.4 allows     local users to cause a denial of service (memory     consumption) or possibly have unspecified other impact     by opening /dev/cuse many times.(CVE-2015-1339i1/4%0

  - A flaw was found in the way the Linux kernel's nested     NMI handler and espfix64 functionalities interacted     during NMI processing. A local, unprivileged user could     use this flaw to crash the system or, potentially,     escalate their privileges on the     system.(CVE-2015-3290i1/4%0

  - Multiple array index errors in     drivers/hid/hid-multitouch.c in the Human Interface     Device (HID) subsystem in the Linux kernel through     3.11, when CONFIG_HID_MULTITOUCH is enabled, allow     physically proximate attackers to cause a denial of     service (heap memory corruption, or NULL pointer     dereference and OOPS) via a crafted     device.(CVE-2013-2897i1/4%0

  - A flaw was found in the way the Linux kernel's futex     subsystem handled the requeuing of certain Priority     Inheritance (PI) futexes. A local, unprivileged user     could use this flaw to escalate their privileges on the     system.(CVE-2014-3153i1/4%0

  - The XFS subsystem in the Linux kernel 4.4 and later     allows local users to cause a denial of service     (fdatasync() failure and system hang) by using the vfs     syscall group in the 'trinity' program, as a result of     a page lock order bug in the XFS seek hole/data     implementation.(CVE-2016-8660i1/4%0

  - A flaw was found in the Linux kernel's key management     system where it was possible for an attacker to     escalate privileges or crash the machine. If a user key     gets negatively instantiated, an error code is cached     in the payload area. A negatively instantiated key may     be then be positively instantiated by updating it with     valid data. However, the -i1/4zupdate key type method     must be aware that the error code may be     there.(CVE-2015-8539i1/4%0

  - It was found that the Linux kernel KVM subsystem's     sysenter instruction emulation was not sufficient. An     unprivileged guest user could use this flaw to escalate     their privileges by tricking the hypervisor to emulate     a SYSENTER instruction in 16-bit mode, if the guest OS     did not initialize the SYSENTER model-specific     registers (MSRs). Note: Certified guest operating     systems for Red Hat Enterprise Linux with KVM do     initialize the SYSENTER MSRs and are thus not     vulnerable to this issue when running on a KVM     hypervisor.(CVE-2015-0239i1/4%0

  - An information leak flaw was found in the way the Linux     kernel handled media device enumerate entities IOCTL     requests. A local user able to access the /dev/media0     device file could use this flaw to leak kernel memory     bytes.(CVE-2014-1739i1/4%0

  - The dgnc_mgmt_ioctl function in     drivers/staging/dgnc/dgnc_mgmt.c in the Linux kernel     through 4.3.3 does not initialize a certain structure     member, which allows local users to obtain sensitive     information from kernel memory via a crafted     application.(CVE-2015-7885i1/4%0

  - An information leak was discovered in the Linux kernel     in cdrom_ioctl_drive_status() function in     drivers/cdrom/cdrom.c that could be used by local     attackers to read kernel memory at certain     location.(CVE-2018-16658i1/4%0

  - A flaw was discovered in the Linux kernel's     implementation of VFIO. An attacker issuing an ioctl     can create a situation where memory is corrupted and     modify memory outside of the expected area. This may     overwrite kernel memory and subvert kernel     execution.(CVE-2016-9083i1/4%0

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invvpid     (Invalidate Translations Based on VPID) instructions.
    On hosts with an Intel processor and invppid VM exit     support, an unprivileged guest user could use these     instructions to crash the guest.(CVE-2014-3646i1/4%0

  - An attacker on a network could abuse a flaw in the IPv6     stack fragment reassembly code to induce kernel memory     corruption on the system, possibly leading to a system     crash.(CVE-2016-9755i1/4%0

  - It was found that a regular user could remove xattr     permissions on files by using the chown or write system     calls. A local attacker could use this flaw to deny     elevated permissions from valid users, services, or     applications, potentially resulting in a denial of     service.(CVE-2015-1350i1/4%0

  - arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux     kernel through 4.7 on PowerPC platforms, when     CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS     users to cause a denial of service (host OS infinite     loop) by making a H_CEDE hypercall during the existence     of a suspended transaction.(CVE-2016-5412i1/4%0

  - An issue was discovered in the proc_pid_stack function     in fs/proc/base.c in the Linux kernel. An attacker with     a local account can trick the stack unwinder code to     leak stack contents to userspace. The fix allows only     root to inspect the kernel stack of an arbitrary     task.(CVE-2018-17972i1/4%0

Additional Changes :

See the Red Hat Enterprise Linux 7.5 Release Notes linked from References.

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2018-1062 advisory.

  - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations,     allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)

  - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not     properly randomize the legacy base address, which makes it easier for local users to defeat the intended     restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or     setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)

  - The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel through 4.13.3 does not ensure that     the CR8-load exiting and CR8-store exiting L0 vmcs02 controls exist in cases where L1 omits the use     TPR shadow vmcs12 control, which allows KVM L2 guest OS users to obtain read and write access to the     hardware CR8 register. (CVE-2017-12154)

  - The bio_map_user_iov and bio_unmap_user functions in block/bio.c in the Linux kernel before 4.13.8 do     unbalanced refcounting when a SCSI I/O vector has small consecutive buffers belonging to the same page.
    The bio_add_pc_page function merges them into one, but the page reference is never dropped. This causes a     memory leak and possible system lockup (exploitable against the host OS by a guest OS user, if a SCSI disk     is passed through to a virtual machine) due to an out-of-memory condition. (CVE-2017-12190)

  - The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port     0x80 an exception can be triggered leading to a kernel panic. (CVE-2017-1000407)

  - The dccp_disconnect function in net/dccp/proto.c in the Linux kernel through 4.14.3 allows local users to     gain privileges or cause a denial of service (use-after-free) via an AF_UNSPEC connect system call during     the DCCP_LISTEN state. (CVE-2017-8824)

  - The move_pages system call in mm/migrate.c in the Linux kernel before 4.12.9 doesn't check the effective     uid of the target process, enabling a local attacker to learn the memory layout of a setuid executable     despite ASLR. (CVE-2017-14140)

  - The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel     through 4.10.6 does not validate addition of certain levels data, which allows 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. (CVE-2017-7294)

  - In all Qualcomm products with Android releases from CAF using the Linux kernel, during DMA allocation, due     to wrong data type of size, allocation size gets truncated which makes allocation succeed when it should     fail. (CVE-2017-9725)

  - A flaw was found in the hugetlb_mcopy_atomic_pte function in mm/hugetlb.c in the Linux kernel before 4.13.
    A superfluous implicit page unlock for VM_SHARED hugetlbfs mapping could trigger a local denial of service     (BUG). (CVE-2017-15127)

  - A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before     4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count     value after it has found a peer network in netns_ids idr, which could lead to double free and memory     corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption     on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully     ruled out, although it is thought to be unlikely. (CVE-2017-15129)

  - Race condition in the ALSA subsystem in the Linux kernel before 4.13.8 allows local users to cause a     denial of service (use-after-free) or possibly have unspecified other impact via crafted /dev/snd/seq     ioctl calls, related to sound/core/seq/seq_clientmgr.c and sound/core/seq/seq_ports.c. (CVE-2017-15265)

  - The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4,     when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net     namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN     capability to sniff an nlmon interface for all Netlink activity on the system. (CVE-2017-17449)

  - The usb_destroy_configuration function in drivers/usb/core/config.c in the USB core subsystem in the Linux     kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before     attempting to release resources, which allows local users to cause a denial of service (out-of-bounds     write access) or possibly have unspecified other impact via a crafted USB device. (CVE-2017-17558)

  - The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of     incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of     uninitialized stack variables that may be returned to an attacker in their uninitialized state. By     manipulating the code flows that precede the handling of these configuration messages, an attacker can     also gain some control over which data will be held in the uninitialized stack variables. This can allow     him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in     this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in     L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels     which were built with the above mitigations. These are the specifics of this vulnerability: In the     function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the following variable is declared     without initialization: struct l2cap_conf_efs efs; In addition, when parsing input configuration     parameters in both of these functions, the switch case for handling EFS elements may skip the memcpy call     that will write to the efs variable: ... case L2CAP_CONF_EFS: if (olen == sizeof(efs)) memcpy(&efs;, (void
    *)val, olen); ... The olen in the above if is attacker controlled, and regardless of that if, in both of     these functions the efs variable would eventually be added to the outgoing configuration request that is     being built: l2cap_add_conf_opt(&ptr;, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs;); So by sending a     configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length     that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the     uninitialized variable would be returned to the attacker (16 bytes). (CVE-2017-1000410)

  - The acpi_smbus_hc_add function in drivers/acpi/sbshc.c in the Linux kernel through 4.14.15 allows local     users to obtain sensitive address information by reading dmesg data from an SBS HC printk call.
    (CVE-2018-5750)

  - The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6     allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving     omission of the firmware name from a certain data structure. (CVE-2016-7913)

  - An elevation of privilege vulnerability in the kernel v4l2 video driver. Product: Android. Versions:
    Android kernel. Android ID A-34624167. (CVE-2017-13166)

  - The rngapi_reset function in crypto/rng.c in the Linux kernel before 4.2 allows attackers to cause a     denial of service (NULL pointer dereference). (CVE-2017-15116)

  - A non-privileged user is able to mount a fuse filesystem on RHEL 6 or 7 and crash a system if an     application punches a hole in a file that does not end aligned to a page boundary. (CVE-2017-15121)

  - A use-after-free flaw was found in fs/userfaultfd.c in the Linux kernel before 4.13.6. The issue is     related to the handling of fork failure when dealing with event messages. Failure to fork correctly can     lead to a situation where a fork event will be removed from an already freed list of events with     userfaultfd_ctx_put(). (CVE-2017-15126)

  - net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN     capability for new, get, and del operations, which allows local users to bypass intended access     restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces.
    (CVE-2017-17448)

  - The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x     before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption)     or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action.
    (CVE-2017-18017)

  - The dm_get_from_kobject function in drivers/md/dm.c in the Linux kernel before 4.14.3 allow local users to     cause a denial of service (BUG) by leveraging a race condition with __dm_destroy during creation and     removal of DM devices. (CVE-2017-18203)

  - The KVM subsystem in the Linux kernel through 4.13.3 allows guest OS users to cause a denial of service     (assertion failure, and hypervisor hang or crash) via an out-of bounds guest_irq value, related to     arch/x86/kvm/vmx.c and virt/kvm/eventfd.c. (CVE-2017-1000252)

  - The futex_requeue function in kernel/futex.c in the Linux kernel before 4.14.15 might allow attackers to     cause a denial of service (integer overflow) or possibly have unspecified other impact by triggering a     negative wake or requeue value. (CVE-2018-6927)

  - In the Linux kernel 4.12, 3.10, 2.6 and possibly earlier versions a race condition vulnerability exists in     the sound system, this can lead to a deadlock and denial of service condition. (CVE-2018-1000004)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
