Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

  - CVE-2017-7346     Li Qiang discovered that the DRM driver for VMware     virtual GPUs does not properly check user-controlled     values in the vmw_surface_define_ioctl() functions for     upper limits. A local user can take advantage of this     flaw to cause a denial of service.

  - CVE-2017-7482     Shi Lei discovered that RxRPC Kerberos 5 ticket handling     code does not properly verify metadata, leading to     information disclosure, denial of service or potentially     execution of arbitrary code.

  - CVE-2017-7533     Fan Wu and Shixiong Zhao discovered a race condition     between inotify events and VFS rename operations     allowing an unprivileged local attacker to cause a     denial of service or escalate privileges.

  - CVE-2017-7541     A buffer overflow flaw in the Broadcom IEEE802.11n PCIe     SoftMAC WLAN driver could allow a local user to cause     kernel memory corruption, leading to a denial of service     or potentially privilege escalation.

  - CVE-2017-7542     An integer overflow vulnerability in the     ip6_find_1stfragopt() function was found allowing a     local attacker with privileges to open raw sockets to     cause a denial of service.

  - CVE-2017-9605     Murray McAllister discovered that the DRM driver for     VMware virtual GPUs does not properly initialize memory,     potentially allowing a local attacker to obtain     sensitive information from uninitialized kernel memory     via a crafted ioctl call.

  - CVE-2017-10810     Li Qiang discovered a memory leak flaw within the VirtIO     GPU driver resulting in denial of service (memory     consumption).

  - CVE-2017-10911 / XSA-216     Anthony Perard of Citrix discovered an information leak     flaw in Xen blkif response handling, allowing a     malicious unprivileged guest to obtain sensitive     information from the host or other guests.

  - CVE-2017-11176     It was discovered that the mq_notify() function does not     set the sock pointer to NULL upon entry into the retry     logic. An attacker can take advantage of this flaw     during a user-space close of a Netlink socket to cause a     denial of service or potentially cause other impact.

  - CVE-2017-1000365     It was discovered that argument and environment pointers     are not taken properly into account to the imposed size     restrictions on arguments and environmental strings     passed through RLIMIT_STACK/RLIMIT_INFINITY. A local     attacker can take advantage of this flaw in conjunction     with other flaws to execute arbitrary code.

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3364-1 advisory.

    It was discovered that the Linux kernel did not properly initialize a Wake- on-Lan data structure. A local     attacker could use this to expose sensitive information (kernel memory). (CVE-2014-9900)

    It was discovered that the Linux kernel did not properly restrict access to /proc/iomem. A local attacker     could use this to expose sensitive information. (CVE-2015-8944)

    Alexander Potapenko discovered a race condition in the Advanced Linux Sound Architecture (ALSA) subsystem     in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory).
    (CVE-2017-1000380)

    Li Qiang discovered that the DRM driver for VMware Virtual GPUs in the Linux kernel did not properly     validate some ioctl arguments. A local attacker could use this to cause a denial of service (system     crash). (CVE-2017-7346)

    Jann Horn discovered that bpf in Linux kernel does not restrict the output of the print_bpf_insn function.
    A local attacker could use this to obtain sensitive address information. (CVE-2017-9150)

    Murray McAllister discovered that the DRM driver for VMware Virtual GPUs in the Linux kernel did not     properly initialize memory. A local attacker could use this to expose sensitive information (kernel     memory). (CVE-2017-9605)

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.

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 hid_input_field() function in     'drivers/hid/hid-core.c' in the Linux kernel before 4.6     allows physically proximate attackers to obtain     sensitive information from kernel memory or cause a     denial of service (out-of-bounds read) by connecting a     device.(CVE-2016-7915i1/4%0

  - The Linux kernel, before version 4.14.2, is vulnerable     to a deadlock caused by     fs/ocfs2/file.c:ocfs2_setattr(), as the function does     not wait for DIO requests before locking the inode.
    This can be exploited by local users to cause a     subsequent denial of service.(CVE-2017-18204i1/4%0

  - The vmw_gb_surface_define_ioctl function (accessible     via DRM_IOCTL_VMW_GB_SURFACE_CREATE) in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel through 4.11.4 defines a backup_handle variable     but does not give it an initial value. If one attempts     to create a GB surface, with a previously allocated DMA     buffer to be used as a backup buffer, the backup_handle     variable does not get written to and is then later     returned to user space, allowing local users to obtain     sensitive information from uninitialized kernel memory     via a crafted ioctl call.(CVE-2017-9605i1/4%0

  - Use-after-free vulnerability in the nfqnl_zcopy     function in net/netfilter/nfnetlink_queue_core.c in the     Linux kernel through 3.13.6 allows attackers to obtain     sensitive information from kernel memory by leveraging     the absence of a certain orphaning operation. NOTE: the     affected code was moved to the skb_zerocopy function in     net/core/skbuff.c before the vulnerability was     announced.(CVE-2014-2568i1/4%0

  - It was found that the Linux kernel's ISO file system     implementation did not correctly limit the traversal of     Rock Ridge extension Continuation Entries (CE). An     attacker with physical access to the system could use     this flaw to trigger an infinite loop in the kernel,     resulting in a denial of service.(CVE-2014-9420i1/4%0

  - An integer overflow vulnerability was found in the     ring_buffer_resize() calculations in which a privileged     user can adjust the size of the ringbuffer message     size. These calculations can create an issue where the     kernel memory allocator will not allocate the correct     count of pages yet expect them to be usable. This can     lead to the ftrace() output to appear to corrupt kernel     memory and possibly be used for privileged escalation     or more likely kernel panic.(CVE-2016-9754i1/4%0

  - A symlink size validation was missing in Linux kernels     built with UDF file system (CONFIG_UDF_FS) support,     allowing the corruption of kernel memory. An attacker     able to mount a corrupted/malicious UDF file system     image could cause the kernel to crash.(CVE-2014-9730i1/4%0

  - In was found that in the Linux kernel, in     vmw_surface_define_ioctl() function in     'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c' file, a     'num_sizes' parameter is assigned a user-controlled     value which is not checked if it is zero. This is used     in a call to kmalloc() and later leads to dereferencing     ZERO_SIZE_PTR, which in turn leads to a GPF and     possibly to a kernel panic.(CVE-2017-7261i1/4%0

  - A race condition flaw was found in the way the Linux     kernel keys management subsystem performed key garbage     collection. A local attacker could attempt accessing a     key while it was being garbage collected, which would     cause the system to crash.(CVE-2014-9529i1/4%0

  - A flaw was found in the Linux kernel's implementation     of i8042 serial ports. An attacker could cause a kernel     panic if they are able to add and remove devices as the     module is loaded.(CVE-2017-18079i1/4%0

  - drivers/hid/hid-pl.c in the Human Interface Device     (HID) subsystem in the Linux kernel through 3.11, when     CONFIG_HID_PANTHERLORD is enabled, allows physically     proximate attackers to cause a denial of service     (heap-based out-of-bounds write) via a crafted     device.(CVE-2013-2892i1/4%0

  - The __clear_user function in     arch/arm64/lib/clear_user.S in the Linux kernel before     3.17.4 on the ARM64 platform allows local users to     cause a denial of service (system crash) by reading one     byte beyond a /dev/zero page boundary.(CVE-2014-7843i1/4%0

  - A divide-by-zero vulnerability was found in a way the     kernel processes TCP connections. The error can occur     if a connection starts another cwnd reduction phase by     setting tp-i1/4zprior_cwnd to the current cwnd (0) in     tcp_init_cwnd_reduction(). A remote, unauthenticated     attacker could use this flaw to crash the kernel     (denial of service).(CVE-2016-2070i1/4%0

  - The adjust_branches function in kernel/bpf/verifier.c     in the Linux kernel before 4.5 does not consider the     delta in the backward-jump case, which allows local     users to obtain sensitive information from kernel     memory by creating a packet filter and then loading     crafted BPF instructions.(CVE-2016-2383i1/4%0

  - System using the infiniband support module ib_srpt were     vulnerable to a denial of service by system crash by a     local attacker who is able to abort writes to a device     using this initiator.(CVE-2016-6327i1/4%0

  - A security flaw was found in the Linux kernel in the     mark_source_chains() function in     'net/ipv4/netfilter/ip_tables.c'. It is possible for a     user-supplied 'ipt_entry' structure to have a large     'next_offset' field. This field is not bounds checked     prior to writing to a counter value at the supplied     offset.(CVE-2016-3134i1/4%0

  - An out-of-bounds access issue was discovered in     yurex_read() in drivers/usb/misc/yurex.c in the Linux     kernel. A local attacker could use user access     read/writes with incorrect bounds checking in the yurex     USB driver to crash the kernel or potentially escalate     privileges.(CVE-2018-16276i1/4%0

  - drivers/media/v4l2-core/videobuf2-v4l2.c in the Linux     kernel before 4.5.3 allows local users to cause a     denial of service (kernel memory write operation) or     possibly have unspecified other impact via a crafted     number of planes in a VIDIOC_DQBUF ioctl     call.(CVE-2016-4568i1/4%0

  - The usb_serial_console_disconnect function in     drivers/usb/serial/console.c in the Linux kernel,     before 4.13.8, allows local users to cause a denial of     service (use-after-free and system crash) or possibly     have unspecified other impact via a crafted USB device,     related to disconnection and failed     setup.(CVE-2017-16525i1/4%0

  - The Linux kernel is vulnerable to a NULL pointer     dereference in the ext4/xattr.c:ext4_xattr_inode_hash()     function. An attacker could trick a legitimate user or     a privileged attacker could exploit this to cause a     NULL pointer dereference with a crafted ext4 image.
    (CVE-2018-1094)
