  script_set_attribute(attribute:"description", value:
"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.

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

CVE-2012-6704, CVE-2016-9793

Eric Dumazet found that a local user with CAP_NET_ADMIN capability
could set a socket's buffer size to be negative, leading to a denial
of service or other security impact. Additionally, in kernel versions
prior to 3.5, any user could do this if sysctl net.core.rmem_max was
changed to a very large value.

CVE-2015-1350 / #770492

Ben Harris reported that local users could remove set-capability
attributes from any file visible to them, allowing a denial of
service.

CVE-2015-8962

Calvin Owens fouund that removing a SCSI device while it was being
accessed through the SCSI generic (sg) driver led to a double- free,
possibly causing a denial of service (crash or memory corruption) or
privilege escalation. This could be exploited by local users with
permision to access a SCSI device node.

CVE-2015-8963

Sasha Levin reported that hot-unplugging a CPU resulted in a
use-after-free by the performance events (perf) subsystem, possibly
causing a denial of service (crash or memory corruption) or privilege
escalation. This could by exploited by any local user.

CVE-2015-8964

It was found that the terminal/serial (tty) subsystem did not reliably
reset the terminal buffer state when the terminal line discipline was
changed. This could allow a local user with access to a terminal
device to read sensitive information from kernel memory.

CVE-2016-7097

Jan Kara found that changing the POSIX ACL of a file never cleared its
set-group-ID flag, which should be done if the user changing it is not
a member of the group-owner. In some cases, this would allow the
user-owner of an executable to gain the privileges of the group-owner.

CVE-2016-7910

Vegard Nossum discovered that a memory allocation failure while
handling a read of /proc/diskstats or /proc/partitions could lead to a
use-after-free, possibly causing a denial of service (crash or memory
corruption) or privilege escalation.

CVE-2016-7911

Dmitry Vyukov reported that a race between ioprio_get() and
ioprio_set() system calls could result in a use-after-free, possibly
causing a denial of service (crash) or leaking sensitive information.

CVE-2016-7915

Benjamin Tissoires found that HID devices could trigger an out-of-
bounds memory access in the HID core. A physically present user could
possibly use this for denial of service (crash) or to leak sensitive
information.

CVE-2016-8399

Qidan He reported that the IPv4 ping socket implementation did not
validate the length of packets to be sent. A user with permisson to
use ping sockets could cause an out-of-bounds read, possibly resulting
in a denial of service or information leak. However, on Debian systems
no users have permission to create ping sockets by default.

CVE-2016-8633

Eyal Itkin reported that the IP-over-Firewire driver (firewire-net)
did not validate the offset or length in link-layer fragmentation
headers. This allowed a remote system connected by Firewire to write
to memory after a packet buffer, leading to a denial of service
(crash) or remote code execution.

CVE-2016-8645

Marco Grassi reported that if a socket filter (BPF program) attached
to a TCP socket truncates or removes the TCP header, this could cause
a denial of service (crash). This was exploitable by any local user.

CVE-2016-8655

Philip Pettersson found that the implementation of packet sockets
(AF_PACKET family) had a race condition between enabling a transmit
ring buffer and changing the version of buffers used, which could
result in a use-after-free. A local user with the CAP_NET_ADMIN
capability could exploit this for privilege escalation.

CVE-2016-9178

Al Viro found that a failure to read data from user memory might lead
to a information leak on the x86 architecture (amd64 or i386).

CVE-2016-9555

Andrey Konovalov reported that the SCTP implementation does not
validate 'out of the blue' packet chunk lengths early enough. A remote
system able could use this to cause a denial of service (crash) or
other security impact for systems using SCTP.

CVE-2016-9576, CVE-2016-10088

Dmitry Vyukov reported that using splice() with the SCSI generic
driver led to kernel memory corruption. Local users with permision to
access a SCSI device node could exploit this for privilege escalation.

CVE-2016-9756

Dmitry Vyukov reported that KVM for the x86 architecture (amd64 or
i386) did not correctly handle the failure of certain instructions
that require software emulation on older processors. This could be
exploited by guest systems to leak sensitive information or for denial
of service (log spam).

CVE-2016-9794

Baozeng Ding reported a race condition in the ALSA (sound) subsystem
that could result in a use-after-free. Local users with access to a
PCM sound device could exploit this for denial of service (crash or
memory corruption) or other security impact.

For Debian 7 'Wheezy', these problems have been fixed in version
3.2.84-1. This version also includes bug fixes from upstream version
3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.
Finally, this version adds the option to mitigate security issues in
the performance events (perf) subsystem by disabling use by
unprivileged users. This can be done by setting sysctl
kernel.perf_event_paranoid=3.

For Debian 8 'Jessie', these problems have been fixed in version
3.16.39-1 which will be included in the next point release (8.6).

We recommend that you upgrade your linux packages.

"An update for kernel is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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

Security Fix(es) :

* It was found that the Linux kernel's IPv6 implementation mishandled
socket options. A local attacker could abuse concurrent access to the
socket options to escalate their privileges, or cause a denial of
service (use-after-free and system crash) via a crafted sendmsg system
call. (CVE-2016-3841, Important)

* Several Moderate and Low impact security issues were found in the
Linux kernel. Space precludes documenting each of these issues in this
advisory. Refer to the CVE links in the References section for a
description of each of these vulnerabilities. (CVE-2013-4312,
CVE-2015-8374, CVE-2015-8543, CVE-2015-8812, CVE-2015-8844,

"The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various
security and bugfixes. The following security bugs were fixed :

  - CVE-2017-5715: Systems with microprocessors utilizing
    speculative execution and indirect branch prediction may
    allow unauthorized disclosure of information to an
    attacker with local user access via a side-channel
    analysis (bnc#1068032). Enhancements and bugfixes over
    the previous fixes have been added to this kernel.

  - CVE-2018-10087: The kernel_wait4 function in
    kernel/exit.c might have allowed local users to cause a
    denial of service by triggering an attempted use of the
    -INT_MIN value (bnc#1089608).

  - CVE-2018-7757: Memory leak in the sas_smp_get_phy_events
    function in drivers/scsi/libsas/sas_expander.c allowed
    local users to cause a denial of service (memory
    consumption) via many read accesses to files in the
    /sys/class/sas_phy directory, as demonstrated by the
    /sys/class/sas_phy/phy-1:0:12/invalid_dword_count file
    (bnc#1084536).

  - CVE-2018-7566: There was a buffer overflow via an
    SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to
    /dev/snd/seq by a local user (bnc#1083483).

  - CVE-2017-0861: Use-after-free vulnerability in the
    snd_pcm_info function in the ALSA subsystem allowed
    attackers to gain privileges via unspecified vectors
    (bnc#1088260).

  - CVE-2018-8822: Incorrect buffer length handling in the
    ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c
    could be exploited by malicious NCPFS servers to crash
    the kernel or execute code (bnc#1086162).

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

  - CVE-2017-18203: The dm_get_from_kobject function in
    drivers/md/dm.c allowed local users to cause a denial of
    service (BUG) by leveraging a race condition with
    __dm_destroy during creation and removal of DM devices
    (bnc#1083242).

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

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

  - CVE-2017-16644: The hdpvr_probe function in
    drivers/media/usb/hdpvr/hdpvr-core.c 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 in
    kernel/futex.c in the Linux kernel 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 (bnc#1080757).

  - CVE-2017-16914: The 'stub_send_ret_submit()' function
    (drivers/usb/usbip/stub_tx.c) 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 in
    drivers/hid/hid-core.c 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, as demonstrated by a Logitech DJ
    receiver (bnc#1010470).

  - CVE-2015-5156: The virtnet_probe function in
    drivers/net/virtio_net.c attempted to support a FRAGLIST
    feature without proper memory allocation, which allowed
    guest OS users to cause a denial of service (buffer
    overflow and memory corruption) via a crafted sequence
    of fragmented packets (bnc#940776).

  - CVE-2017-12190: The bio_map_user_iov and bio_unmap_user
    functions in block/bio.c did 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
    (bnc#1062568).

  - CVE-2017-16912: The 'get_pipe()' function
    (drivers/usb/usbip/stub_rx.c) 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
    (drivers/usb/usbip/stub_rx.c) 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).

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

"From Red Hat Security Advisory 2016:2574 :

An update for kernel is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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

Security Fix(es) :

* It was found that the Linux kernel's IPv6 implementation mishandled
socket options. A local attacker could abuse concurrent access to the
socket options to escalate their privileges, or cause a denial of
service (use-after-free and system crash) via a crafted sendmsg system
call. (CVE-2016-3841, Important)

* Several Moderate and Low impact security issues were found in the
Linux kernel. Space precludes documenting each of these issues in this
advisory. Refer to the CVE links in the References section for a
description of each of these vulnerabilities. (CVE-2013-4312,
CVE-2015-8374, CVE-2015-8543, CVE-2015-8812, CVE-2015-8844,
CVE-2015-8845, CVE-2016-2053, CVE-2016-2069, CVE-2016-2847,
CVE-2016-3156, CVE-2016-4581, CVE-2016-4794, CVE-2016-5412,

CVE-2016-4569, CVE-2016-4578)

Red Hat would like to thank Philip Pettersson (Samsung) for reporting
CVE-2016-2053; Tetsuo Handa for reporting CVE-2016-2847; the Virtuozzo
kernel team and Solar Designer (Openwall) for reporting CVE-2016-3156;
Justin Yackoski (Cryptonite) for reporting CVE-2016-2117; and Linn
Crosetto (HP) for reporting CVE-2016-3699. The CVE-2015-8812 issue was
discovered by Venkatesh Pottem (Red Hat Engineering); the
CVE-2015-8844 and CVE-2015-8845 issues were discovered by Miroslav
Vadkerti (Red Hat Engineering); the CVE-2016-4581 issue was discovered
by Eric W. Biederman (Red Hat); the CVE-2016-6198 issue was discovered
by CAI Qian (Red Hat); and the CVE-2016-3070 issue was discovered by
