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 :

  - Array index error in the tcm_vhost_make_tpg function in     drivers/vhost/scsi.c in the Linux kernel before 4.0     might allow guest OS users to cause a denial of service     (memory corruption) or possibly have unspecified other     impact via a crafted VHOST_SCSI_SET_ENDPOINT ioctl     call. NOTE: the affected function was renamed to     vhost_scsi_make_tpg before the vulnerability was     announced.(CVE-2015-4036i1/4%0

  - The llc_cmsg_rcv function in net/llc/af_llc.c in the     Linux kernel before 4.5.5 does not initialize a certain     data structure, which allows attackers to obtain     sensitive information from kernel stack memory by     reading a message.(CVE-2016-4485i1/4%0

  - The nr_recvmsg function in net/netrom/af_netrom.c in     the Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7269i1/4%0

  - The mct_u232_msr_to_state function in     drivers/usb/serial/mct_u232.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted USB device without two     interrupt-in endpoint descriptors.(CVE-2016-3136i1/4%0

  - An out-of-bounds memory access flaw, CVE-2014-7825, was     found in the syscall tracing functionality of the Linux     kernel's perf subsystem. A local, unprivileged user     could use this flaw to crash the system. Additionally,     an out-of-bounds memory access flaw, CVE-2014-7826, was     found in the syscall tracing functionality of the Linux     kernel's ftrace subsystem. On a system with ftrace     syscall tracing enabled, a local, unprivileged user     could use this flaw to crash the system, or escalate     their privileges.(CVE-2014-7826i1/4%0

  - Linux kernel built with the Kernel-based Virtual     Machine (CONFIG_KVM) support is vulnerable to a null     pointer dereference flaw. It could occur on x86     platform, when emulating an undefined instruction. An     attacker could use this flaw to crash the host kernel     resulting in DoS.(CVE-2016-8630i1/4%0

  - A flaw was found in the Linux kernel's ext4 filesystem.
    A local user can cause an out-of-bound access in     ext4_get_group_info function, a denial of service, and     a system crash by mounting and operating on a crafted     ext4 filesystem image.(CVE-2018-10881i1/4%0

  - The arch_timer_reg_read_stable macro in     arch/arm64/include/asm/arch_timer.h in the Linux kernel     before 4.13 allows local users to cause a denial of     service (infinite recursion) by writing to a file under     /sys/kernel/debug in certain circumstances, as     demonstrated by a scenario involving debugfs, ftrace,     PREEMPT_TRACER, and     FUNCTION_GRAPH_TRACER.(CVE-2017-18261i1/4%0

  - The ip6_route_add function in net/ipv6/route.c in the     Linux kernel through 3.13.6 does not properly count the     addition of routes, which allows remote attackers to     cause a denial of service (memory consumption) via a     flood of ICMPv6 Router Advertisement     packets.(CVE-2014-2309i1/4%0

  - In the Linux kernel before 4.20.2, kernel/sched/fair.c     mishandles leaf cfs_rq's, which allows attackers to     cause a denial of service (infinite loop in     update_blocked_averages) or possibly have unspecified     other impact by inducing a high load.(CVE-2018-20784i1/4%0

  - An issue was discovered in the F2FS filesystem code in     fs/f2fs/inline.c in the Linux kernel. A denial of     service due to the out-of-bounds memory access can     occur for a modified f2fs filesystem     image.(CVE-2018-13099i1/4%0

  - An out-of-bounds write vulnerability was found in the     Linux kernel's vmw_surface_define_ioctl() function, in     the 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file. Due     to the nature of the flaw, privilege escalation cannot     be fully ruled out, although we believe it is     unlikely.(CVE-2017-7294i1/4%0

  - A flaw was found in the way the Linux kernel's KVM     subsystem handled non-canonical addresses when     emulating instructions that change the RIP (for     example, branches or calls). A guest user with access     to an I/O or MMIO region could use this flaw to crash     the guest.(CVE-2014-3647i1/4%0

  - The __munlock_pagevec function in mm/mlock.c in the     Linux kernel, before 4.11.4, allows local users to     cause a denial of service (NR_MLOCK accounting     corruption) via crafted use of mlockall and munlockall     system calls.(CVE-2017-18221i1/4%0

  - ** RESERVED ** This candidate has been reserved by an     organization or individual that will use it when     announcing a new security problem. When the candidate     has been publicized, the details for this candidate     will be provided.(CVE-2018-1120i1/4%0

  - The proc_connectinfo() function in     'drivers/usb/core/devio.c' in the Linux kernel through     4.6 does not initialize a certain data structure, which     allows local users to obtain sensitive information from     kernel stack memory via a crafted USBDEVFS_CONNECTINFO     ioctl call. The stack object 'ci' has a total size of 8     bytes. Its last 3 bytes are padding bytes which are not     initialized and are leaked to     userland.(CVE-2016-4482i1/4%0

  - A vulnerability was found in the Linux kernel. An     unprivileged local user could trigger oops in     shash_async_export() by attempting to force the     in-kernel hashing algorithms into decrypting an empty     data set.(CVE-2016-8646i1/4%0

  - An issue was discovered in the btrfs filesystem code in     the Linux kernel. An invalid NULL pointer dereference     in btrfs_root_node() when mounting a crafted btrfs     image is due to a lack of chunk block group mapping     validation in btrfs_read_block_groups() in the     fs/btrfs/extent-tree.c function and a lack of     empty-tree checks in check_leaf() in     fs/btrfs/tree-checker.c function. This could lead to a     system crash and a denial of service.(CVE-2018-14612i1/4%0

  - It was found that the Linux kernel's TCP/IP protocol     suite implementation for IPv6 allowed the Hop Limit     value to be set to a smaller value than the default     one. An attacker on a local network could use this flaw     to prevent systems on that network from sending or     receiving network packets.(CVE-2015-2922i1/4%0

  - A NULL-pointer dereference flaw was found in the     kernel, which is caused by a race between revoking a     user-type key and reading from it. The issue could be     triggered by an unprivileged user with a local account,     causing the kernel to crash (denial of     service).(CVE-2015-7550i1/4%0

The SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-1068: Fixed flaw in the implementation of     32-bit syscall interface for bridging. This allowed a     privileged user to arbitrarily write to a limited range     of kernel memory (bnc#1085107).

  - CVE-2017-18221: The __munlock_pagevec function allowed     local users to cause a denial of service (NR_MLOCK     accounting corruption) via crafted use of mlockall and     munlockall system calls (bnc#1084323).

  - CVE-2018-1066: Prevent NULL pointer dereference in     fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an     attacker controlling a CIFS server to kernel panic a     client that has this server mounted, because an empty     TargetInfo field in an NTLMSSP setup negotiation     response was mishandled during session recovery     (bnc#1083640).

  - CVE-2017-13166: Prevent elevation of privilege     vulnerability in the kernel v4l2 video driver     (bnc#1072865).

  - CVE-2017-16911: The vhci_hcd driver allowed local     attackers to disclose kernel memory addresses.
    Successful exploitation required that a USB device was     attached over IP (bnc#1078674).

  - CVE-2017-15299: The KEYS subsystem mishandled use of     add_key for a key that already exists but is     uninstantiated, which allowed local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     crafted system call (bnc#1063416).

  - CVE-2017-18208: The madvise_willneed function kernel     allowed local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping (bnc#1083494).

  - CVE-2018-7566: The ALSA sequencer core initializes the     event pool on demand by invoking snd_seq_pool_init()     when the first write happens and the pool is empty. A     user could have reset the pool size manually via ioctl     concurrently, which may have lead UAF or out-of-bound     access (bsc#1083483).

  - CVE-2017-18204: The ocfs2_setattr function allowed local     users to cause a denial of service (deadlock) via DIO     requests (bnc#1083244).

  - CVE-2017-16644: The hdpvr_probe function allowed local     users to cause a denial of service (improper error     handling and system crash) or possibly have unspecified     other impact via a crafted USB device (bnc#1067118).

  - CVE-2018-6927: The futex_requeue function allowed     attackers to cause a denial of service (integer     overflow) or possibly have unspecified other impact by     triggering a negative wake or requeue value     (bnc#1080757).

  - CVE-2017-16914: The 'stub_send_ret_submit()' function     allowed attackers to cause a denial of service (NULL     pointer dereference) via a specially crafted USB over IP     packet (bnc#1078669).

  - CVE-2016-7915: The hid_input_field function allowed     physically proximate attackers to obtain sensitive     information from kernel memory or cause a denial of     service (out-of-bounds read) by connecting a device     (bnc#1010470).

  - CVE-2017-12190: The bio_map_user_iov and bio_unmap_user     functions did unbalanced refcounting when a SCSI I/O     vector had small consecutive buffers belonging to the     same page. The bio_add_pc_page function merged them into     one, but the page reference was never dropped. This     caused 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 (bnc#1062568).

  - CVE-2017-16912: The 'get_pipe()' function allowed     attackers to cause a denial of service (out-of-bounds     read) via a specially crafted USB over IP packet     (bnc#1078673).

  - CVE-2017-16913: The 'stub_recv_cmd_submit()' function     when handling CMD_SUBMIT packets allowed attackers to     cause a denial of service (arbitrary memory allocation)     via a specially crafted USB over IP packet     (bnc#1078672).

  - CVE-2018-5332: The rds_message_alloc_sgs() function did     not validate a value that is used during DMA page     allocation, leading to a heap-based out-of-bounds write     (related to the rds_rdma_extra_size function in     net/rds/rdma.c) (bnc#1075621).

  - CVE-2018-5333: The rds_cmsg_atomic function in     net/rds/rdma.c mishandled cases where page pinning fails     or an invalid address is supplied, leading to an     rds_atomic_free_op NULL pointer dereference     (bnc#1075617).

  - CVE-2017-18017: The tcpmss_mangle_packet function     allowed 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 (bnc#1074488).

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

The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2018-1068: Fixed flaw in the implementation of     32-bit syscall interface for bridging. This allowed a     privileged user to arbitrarily write to a limited range     of kernel memory (bnc#1085107).

  - CVE-2017-18221: The __munlock_pagevec function allowed     local users to cause a denial of service (NR_MLOCK     accounting corruption) via crafted use of mlockall and     munlockall system calls (bnc#1084323).

  - CVE-2018-1066: Prevent NULL pointer dereference in     fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an     attacker controlling a CIFS server to kernel panic a     client that has this server mounted, because an empty     TargetInfo field in an NTLMSSP setup negotiation     response was mishandled during session recovery     (bnc#1083640).

  - CVE-2017-13166: Prevent elevation of privilege     vulnerability in the kernel v4l2 video driver     (bnc#1072865).

  - CVE-2017-16911: The vhci_hcd driver allowed local     attackers to disclose kernel memory addresses.
    Successful exploitation required that a USB device was     attached over IP (bnc#1078674).

  - CVE-2017-15299: The KEYS subsystem mishandled use of     add_key for a key that already exists but is     uninstantiated, which allowed local users to cause a     denial of service (NULL pointer dereference and system     crash) or possibly have unspecified other impact via a     crafted system call (bnc#1063416).

  - CVE-2017-18208: The madvise_willneed function kernel     allowed local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping (bnc#1083494).

  - CVE-2018-7566: The ALSA sequencer core initializes the     event pool on demand by invoking snd_seq_pool_init()     when the first write happens and the pool is empty. A     user could have reset the pool size manually via ioctl     concurrently, which may have lead UAF or out-of-bound     access (bsc#1083483).

  - CVE-2017-18204: The ocfs2_setattr function allowed local     users to cause a denial of service (deadlock) via DIO     requests (bnc#1083244).

  - CVE-2017-16644: The hdpvr_probe function allowed local     users to cause a denial of service (improper error     handling and system crash) or possibly have unspecified     other impact via a crafted USB device (bnc#1067118).

  - CVE-2018-6927: The futex_requeue function allowed     attackers to cause a denial of service (integer     overflow) or possibly have unspecified other impact by     triggering a negative wake or requeue value     (bnc#1080757).

  - CVE-2017-16914: The 'stub_send_ret_submit()' function     allowed attackers to cause a denial of service (NULL     pointer dereference) via a specially crafted USB over IP     packet (bnc#1078669).

  - CVE-2016-7915: The hid_input_field function allowed     physically proximate attackers to obtain sensitive     information from kernel memory or cause a denial of     service (out-of-bounds read) by connecting a device     (bnc#1010470).

  - CVE-2017-12190: The bio_map_user_iov and bio_unmap_user     functions did unbalanced refcounting when a SCSI I/O     vector had small consecutive buffers belonging to the     same page. The bio_add_pc_page function merged them into     one, but the page reference was never dropped. This     caused 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 (bnc#1062568).

  - CVE-2017-16912: The 'get_pipe()' function allowed     attackers to cause a denial of service (out-of-bounds     read) via a specially crafted USB over IP packet     (bnc#1078673).

  - CVE-2017-16913: The 'stub_recv_cmd_submit()' function     when handling CMD_SUBMIT packets allowed attackers to     cause a denial of service (arbitrary memory allocation)     via a specially crafted USB over IP packet     (bnc#1078672).

  - CVE-2018-5332: The rds_message_alloc_sgs() function did     not validate a value that is used during DMA page     allocation, leading to a heap-based out-of-bounds write     (related to the rds_rdma_extra_size function in     net/rds/rdma.c) (bnc#1075621).

  - CVE-2018-5333: The rds_cmsg_atomic function in     net/rds/rdma.c mishandled cases where page pinning fails     or an invalid address is supplied, leading to an     rds_atomic_free_op NULL pointer dereference     (bnc#1075617).

  - CVE-2017-18017: The tcpmss_mangle_packet function     allowed 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 (bnc#1074488).

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

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3655-1 advisory.

    Jann Horn and Ken Johnson discovered that microprocessors utilizing speculative execution of a memory read     may allow unauthorized memory reads via a sidechannel attack. This flaw is known as Spectre Variant 4. A     local attacker could use this to expose sensitive information, including kernel memory. (CVE-2018-3639)

    Jan H. Schnherr discovered that the Xen subsystem did not properly handle block IO merges correctly in     some situations. An attacker in a guest vm could use this to cause a denial of service (host crash) or     possibly gain administrative privileges in the host. (CVE-2017-12134)

    It was discovered that the Bluetooth HIP Protocol implementation in the Linux kernel did not properly     validate HID connection setup information. An attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2017-13220)

    It was discovered that a buffer overread vulnerability existed in the keyring subsystem of the Linux     kernel. A local attacker could possibly use this to expose sensitive information (kernel memory).
    (CVE-2017-13305)

    It was discovered that the netlink subsystem in the Linux kernel did not properly restrict observations of     netlink messages to the appropriate net namespace. A local attacker could use this to expose sensitive     information (kernel netlink traffic). (CVE-2017-17449)

    It was discovered that a race condition existed in the i8042 serial device driver implementation in the     Linux kernel. A physically proximate attacker could use this to cause a denial of service (system crash)     or possibly execute arbitrary code. (CVE-2017-18079)

    It was discovered that a race condition existed in the Device Mapper component of the Linux kernel. A     local attacker could use this to cause a denial of service (system crash). (CVE-2017-18203)

    It was discovered that a race condition existed in the OCFS2 file system implementation in the Linux     kernel. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2017-18204)

    It was discovered that an infinite loop could occur in the madvise(2) implementation in the Linux kernel     in certain circumstances. A local attacker could use this to cause a denial of service (system hang).
    (CVE-2017-18208)

    Kefeng Wang discovered that a race condition existed in the memory locking implementation in the Linux     kernel. A local attacker could use this to cause a denial of service. (CVE-2017-18221)

    Silvio Cesare discovered a buffer overwrite existed in the NCPFS implementation in the Linux kernel. A     remote attacker controlling a malicious NCPFS server could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2018-8822)

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

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