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

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2014:1843 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux     operating system.

    * A race condition flaw was found in the way the Linux kernel's KVM     subsystem handled PIT (Programmable Interval Timer) emulation. A guest user     who has access to the PIT I/O ports could use this flaw to crash the host.
    (CVE-2014-3611, Important)

    * A memory corruption flaw was found in the way the USB ConnectTech     WhiteHEAT serial driver processed completion commands sent via USB Request     Blocks buffers. An attacker with physical access to the system could use     this flaw to crash the system or, potentially, escalate their privileges on     the system. (CVE-2014-3185, Moderate)

    * It was found that the Linux kernel's KVM subsystem did not handle the VM     exits gracefully for the invept (Invalidate Translations Derived from EPT)     and invvpid (Invalidate Translations Based on VPID) instructions. On hosts     with an Intel processor and invept/invppid VM exit support, an unprivileged     guest user could use these instructions to crash the guest. (CVE-2014-3645,     CVE-2014-3646, Moderate)

    Red Hat would like to thank Lars Bull of Google for reporting     CVE-2014-3611, and the Advanced Threat Research team at Intel Security for     reporting CVE-2014-3645 and CVE-2014-3646.

    This update also fixes the following bugs:

    * This update fixes several race conditions between PCI error recovery     callbacks and potential calls of the ifup and ifdown commands in the tg3     driver. When triggered, these race conditions could cause a kernel crash.
    (BZ#1142570)

    * Previously, GFS2 failed to unmount a sub-mounted GFS2 file system if its     parent was also a GFS2 file system. This problem has been fixed by adding     the appropriate d_op->d_hash() routine call for the last component of the     mount point path in the path name lookup mechanism code (namei).
    (BZ#1145193)

    * Due to previous changes in the virtio-net driver, a Red Hat Enterprise     Linux 6.6 guest was unable to boot with the mgr_rxbuf=off option     specified. This was caused by providing the page_to_skb() function with an     incorrect packet length in the driver's Rx path. This problem has been     fixed and the guest in the described scenario can now boot successfully.
    (BZ#1148693)

    * When using one of the newer IPSec Authentication Header (AH) algorithms     with Openswan, a kernel panic could occur. This happened because the     maximum truncated ICV length was too small. To fix this problem, the     MAX_AH_AUTH_LEN parameter has been set to 64. (BZ#1149083)

    * A bug in the IPMI driver caused the kernel to panic when an IPMI     interface was removed using the hotmod script. The IPMI driver has been     fixed to properly clean the relevant data when removing an IPMI interface.
    (BZ#1149578)

    * Due to a bug in the IPMI driver, the kernel could panic when adding an     IPMI interface that was previously removed using the hotmod script.
    This update fixes this bug by ensuring that the relevant shadow structure     is initialized at the right time. (BZ#1149580)

    All kernel users are advised to upgrade to these updated packages, which     contain backported patches to correct these issues. The system must be     rebooted for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Multiple vulnerabilities has been found and corrected in the Linux kernel :

The WRMSR processing functionality in the KVM subsystem in the Linux kernel through 3.17.2 does not properly handle the writing of a non-canonical address to a model-specific register, which allows guest OS users to cause a denial of service (host OS crash) by leveraging guest OS privileges, related to the wrmsr_interception function in arch/x86/kvm/svm.c and the handle_wrmsr function in arch/x86/kvm/vmx.c (CVE-2014-3610).

Race condition in the __kvm_migrate_pit_timer function in arch/x86/kvm/i8254.c in the KVM subsystem in the Linux kernel through 3.17.2 allows guest OS users to cause a denial of service (host OS crash) by leveraging incorrect PIT emulation (CVE-2014-3611).

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.12 does not have an exit handler for the INVEPT instruction, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application (CVE-2014-3645).

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel through 3.17.2 does not have an exit handler for the INVVPID instruction, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application (CVE-2014-3646).

arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel through 3.17.2 does not properly perform RIP changes, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application (CVE-2014-3647).

The SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (system crash) via a malformed ASCONF chunk, related to net/sctp/sm_make_chunk.c and net/sctp/sm_statefuns.c (CVE-2014-3673).

The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (panic) via duplicate ASCONF chunks that trigger an incorrect uncork within the side-effect interpreter (CVE-2014-3687).

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm access, as demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU (CVE-2014-3690).

kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the perf subsystem, which allows local users to cause a denial of service (out-of-bounds read and OOPS) or bypass the ASLR protection mechanism via a crafted application (CVE-2014-7825).

kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the ftrace subsystem, which allows local users to gain privileges or cause a denial of service (invalid pointer dereference) via a crafted application (CVE-2014-7826).

The pivot_root implementation in fs/namespace.c in the Linux kernel through 3.17 does not properly interact with certain locations of a chroot directory, which allows local users to cause a denial of service (mount-tree loop) via . (dot) values in both arguments to the pivot_root system call (CVE-2014-7970).

The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.17.2 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to cause a denial of service (host OS page unpinning) or possibly have unspecified other impact by leveraging guest OS privileges. NOTE: this vulnerability exists because of an incorrect fix for CVE-2014-3601 (CVE-2014-8369).

The updated packages provides a solution for these security issues.

  - A flaw was found in the way the Linux kernel's     kvm_iommu_map_pages() function handled IOMMU mapping     failures. A privileged user in a guest with an assigned     host device could use this flaw to crash the     host.(CVE-2014-3601)

  - It was found that KVM's Write to Model Specific     Register (WRMSR) instruction emulation would write     non-canonical values passed in by the guest to certain     MSRs in the host's context. A privileged guest user     could use this flaw to crash the host.(CVE-2014-3610)

  - A race condition flaw was found in the way the Linux     kernel's KVM subsystem handled PIT (Programmable     Interval Timer) emulation. A guest user who has access     to the PIT I/O ports could use this flaw to crash the     host.(CVE-2014-3611)

  - A flaw was found in the way the Linux kernel's keys     subsystem handled the termination condition in the     associative array garbage collection functionality. A     local, unprivileged user could use this flaw to crash     the system.(CVE-2014-3631)

  - It was found that the Linux kernel's KVM subsystem did     not handle the VM exits gracefully for the invept     (Invalidate Translations Derived from EPT)     instructions.
