    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to privilege escalation, denial of service or information leaks. - CVE-2017-7518 Andy Lutomirski discovered that KVM is prone to an incorrect debug exception (#DB) error occurring while emulating a syscall instruction. A process inside a guest can take advantage of this flaw for privilege escalation inside a guest. - CVE-2017-7558 (stretch only) Stefano Brivio of Red Hat discovered that the SCTP subsystem is prone to a data leak vulnerability due to an out-of-bounds read flaw, allowing to leak up to 100 uninitialized bytes to userspace. - CVE-2017-10661 (jessie only) Dmitry Vyukov of Google reported that the timerfd facility does not properly handle certain concurrent operations on a single file descriptor. This allows a local attacker to cause a denial of service or potentially execute arbitrary code. - CVE-2017-11600 Bo Zhang reported that the xfrm subsystem does not properly validate one of the parameters to a netlink message. Local users with the CAP_NET_ADMIN capability can use this to cause a denial of service or potentially to execute arbitrary code. - CVE-2017-12134 / #866511 / XSA-229 Jan H. Schoenherr of Amazon discovered that when Linux is running in a Xen PV domain on an x86 system, it may incorrectly merge block I/O requests. A buggy or malicious guest may trigger this bug in dom0 or a PV driver domain, causing a denial of service or potentially execution of arbitrary code. This issue can be mitigated by disabling merges on the underlying back-end block devices, e.g.:echo 2 > /sys/block/nvme0n1/queue/nomerges - CVE-2017-12146 (stretch only) Adrian Salido of Google reported a race condition in access to the

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

  - CVE-2017-7518
    Andy Lutomirski discovered that KVM is prone to an
    incorrect debug exception (#DB) error occurring while
    emulating a syscall instruction. A process inside a
    guest can take advantage of this flaw for privilege
    escalation inside a guest.

  - CVE-2017-7558 (stretch only)
    Stefano Brivio of Red Hat discovered that the SCTP
    subsystem is prone to a data leak vulnerability due to
    an out-of-bounds read flaw, allowing to leak up to 100
    uninitialized bytes to userspace.

  - CVE-2017-10661 (jessie only)
    Dmitry Vyukov of Google reported that the timerfd
    facility does not properly handle certain concurrent
    operations on a single file descriptor. This allows a
    local attacker to cause a denial of service or
    potentially execute arbitrary code.

  - CVE-2017-11600
    Bo Zhang reported that the xfrm subsystem does not
    properly validate one of the parameters to a netlink
    message. Local users with the CAP_NET_ADMIN capability
    can use this to cause a denial of service or potentially
    to execute arbitrary code.

  - CVE-2017-12134 / #866511 / XSA-229
    Jan H. Schoenherr of Amazon discovered that when Linux
    is running in a Xen PV domain on an x86 system, it may
    incorrectly merge block I/O requests. A buggy or
    malicious guest may trigger this bug in dom0 or a PV
    driver domain, causing a denial of service or
    potentially execution of arbitrary code.

  This issue can be mitigated by disabling merges on the underlying
  back-end block devices, e.g.:echo 2 >
  /sys/block/nvme0n1/queue/nomerges

  - CVE-2017-12146 (stretch only)
    Adrian Salido of Google reported a race condition in
    access to the'driver_override' attribute for platform
    devices in sysfs. If unprivileged users are permitted to
    access this attribute, this might allow them to gain
    privileges.

  - CVE-2017-12153
    Bo Zhang reported that the cfg80211 (wifi) subsystem
    does not properly validate the parameters to a netlink
    message. Local users with the CAP_NET_ADMIN capability
    (in any user namespace with a wifi device) can use this
    to cause a denial of service.

  - CVE-2017-12154
    Jim Mattson of Google reported that the KVM
    implementation for Intel x86 processors did not
    correctly handle certain nested hypervisor
    configurations. A malicious guest (or nested guest in a
    suitable L1 hypervisor) could use this for denial of
    service.

  - CVE-2017-14106
    Andrey Konovalov discovered that a user-triggerable
    division by zero in the tcp_disconnect() function could
    result in local denial of service.

  - CVE-2017-14140
    Otto Ebeling reported that the move_pages() system call
    performed insufficient validation of the UIDs of the
    calling and target processes, resulting in a partial
    ASLR bypass. This made it easier for local users to
    exploit vulnerabilities in programs installed with the
    set-UID permission bit set.

  - CVE-2017-14156
    'sohu0106' reported an information leak in the atyfb
    video driver. A local user with access to a framebuffer
    device handled by this driver could use this to obtain
    sensitive information.

  - CVE-2017-14340
    Richard Wareing discovered that the XFS implementation
    allows the creation of files with the 'realtime' flag on
    a filesystem with no realtime device, which can result
    in a crash (oops). A local user with access to an XFS
    filesystem that does not have a realtime device can use
    this for denial of service.

  - CVE-2017-14489
    ChunYu Wang of Red Hat discovered that the iSCSI
    subsystem does not properly validate the length of a
    netlink message, leading to memory corruption. A local
    user with permission to manage iSCSI devices can use
    this for denial of service or possibly to execute
    arbitrary code.

  - CVE-2017-14497 (stretch only)
    Benjamin Poirier of SUSE reported that vnet headers are
    not properly handled within the tpacket_rcv() function
    in the raw packet (af_packet) feature. A local user with
    the CAP_NET_RAW capability can take advantage of this
    flaw to cause a denial of service (buffer overflow, and
    disk and memory corruption) or have other impact.

  - CVE-2017-1000111
    Andrey Konovalov of Google reported a race condition in
    the raw packet (af_packet) feature. Local users with the
    CAP_NET_RAW capability can use this for denial of
    service or possibly to execute arbitrary code.

  - CVE-2017-1000112
    Andrey Konovalov of Google reported a race condition
    flaw in the UDP Fragmentation Offload (UFO) code. A
    local user can use this flaw for denial of service or
    possibly to execute arbitrary code.

  - CVE-2017-1000251 / #875881
    Armis Labs discovered that the Bluetooth subsystem does
    not properly validate L2CAP configuration responses,
    leading to a stack-based buffer overflow. This is one of
    several vulnerabilities dubbed 'Blueborne'. A nearby
    attacker can use this to cause a denial of service or
    possibly to execute arbitrary code on a system with
    Bluetooth enabled.

  - CVE-2017-1000252 (stretch only)
    Jan H. Schoenherr of Amazon reported that the KVM
    implementation for Intel x86 processors did not
    correctly validate interrupt injection requests. A local
    user with permission to use KVM could use this for
    denial of service.

  - CVE-2017-1000370
    The Qualys Research Labs reported that a large argument
    or environment list can result in ASLR bypass for 32-bit
    PIE binaries.

  - CVE-2017-1000371
    The Qualys Research Labs reported that a large argument
    or environment list can result in a stack/heap clash for
    32-bit PIE binaries.

  - CVE-2017-1000380
    Alexander Potapenko of Google reported a race condition
    in the ALSA (sound) timer driver, leading to an
    information leak. A local user with permission to access
    sound devices could use this to obtain sensitive
    information.

Debian disables unprivileged user namespaces by default, but if they
are enabled (via the kernel.unprivileged_userns_clone sysctl) then
CVE-2017-11600, CVE-2017-14497 and CVE-2017-1000111 can be exploited
by any local user."

    descriptionThe SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.92 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-1000252: The KVM subsystem in the Linux kernel allowed 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 (bnc#1058038). - CVE-2017-11472: The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel did not flush the operand cache and causes a kernel stack dump, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table (bnc#1049580). - CVE-2017-12134: The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation (bnc#1051790 bsc#1053919). - CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash (bnc#1058410). - CVE-2017-12154: The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel did not ensure that the

"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.92 to
receive various security and bugfixes. The following security bugs
were fixed :

  - CVE-2017-1000252: The KVM subsystem in the Linux kernel
    allowed 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 (bnc#1058038).

  - CVE-2017-11472: The acpi_ns_terminate() function in
    drivers/acpi/acpica/nsutils.c in the Linux kernel did
    not flush the operand cache and causes a kernel stack
    dump, which allowed local users to obtain sensitive
    information from kernel memory and bypass the KASLR
    protection mechanism (in the kernel through 4.9) via a
    crafted ACPI table (bnc#1049580).

  - CVE-2017-12134: The xen_biovec_phys_mergeable function
    in drivers/xen/biomerge.c in Xen might allow local OS
    guest users to corrupt block device data streams and
    consequently obtain sensitive memory information, cause
    a denial of service, or gain host OS privileges by
    leveraging incorrect block IO merge-ability calculation
    (bnc#1051790 bsc#1053919).

  - CVE-2017-12153: A security flaw was discovered in the
    nl80211_set_rekey_data() function in
    net/wireless/nl80211.c in the Linux kernel This function
    did not check whether the required attributes are
    present in a Netlink request. This request can be issued
    by a user with the CAP_NET_ADMIN capability and may
    result in a NULL pointer dereference and system crash
    (bnc#1058410).

  - CVE-2017-12154: The prepare_vmcs02 function in
    arch/x86/kvm/vmx.c in the Linux kernel did 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 allowed KVM L2 guest
    OS users to obtain read and write access to the hardware
    CR8 register (bnc#1058507).

  - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2)
    allowed reinstallation of the Group Temporal Key (GTK)
    during the group key handshake, allowing an attacker
    within radio range to replay frames from access points
    to clients (bnc#1056061 1063479 1063667 1063671).

  - CVE-2017-14051: An integer overflow in the
    qla2x00_sysfs_write_optrom_ctl function in
    drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel
    allowed local users to cause a denial of service (memory
    corruption and system crash) by leveraging root access
    (bnc#1056588).

  - CVE-2017-14106: The tcp_disconnect function in
    net/ipv4/tcp.c in the Linux kernel allowed local users
    to cause a denial of service (__tcp_select_window
    divide-by-zero error and system crash) by triggering a
    disconnect within a certain tcp_recvmsg code path
    (bnc#1056982).

  - CVE-2017-14489: The iscsi_if_rx function in
    drivers/scsi/scsi_transport_iscsi.c in the Linux kernel
    allowed local users to cause a denial of service (panic)
    by leveraging incorrect length validation (bnc#1059051).

  - CVE-2017-15265: Use-after-free vulnerability in the
    Linux kernel before 4.14-rc5 allowed local users to have
    unspecified impact via vectors related to /dev/snd/seq
    (bnc#1062520).

  - CVE-2017-15649: net/packet/af_packet.c in the Linux
    kernel allowed local users to gain privileges via
    crafted system calls that trigger mishandling of
    packet_fanout data structures, because of a race
    condition (involving fanout_add and packet_do_bind) that
    leads to a use-after-free, a different vulnerability
    than CVE-2017-6346 (bnc#1064388).

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

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

    descriptionThe remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities: - Integer overflow in the aio_setup_single_vector function in fs/aio.c in the Linux kernel 4.0 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. NOTE: this vulnerability exists because of a CVE-2012-6701 regression. (CVE-2015-8830) - A weakness was found in the Linux ASLR implementation. Any user able to running 32-bit applications in a x86 machine can disable ASLR by setting the RLIMIT_STACK resource to unlimited. (CVE-2016-3672) - 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. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2016-7913) - Use-after-free vulnerability in the snd_pcm_info() function in the ALSA subsystem in the Linux kernel allows attackers to induce a kernel memory corruption and possibly crash or lock up a system. Due to the nature of the flaw, a privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-0861) - A reachable assertion failure flaw was found in the Linux kernel built with KVM virtualisation(CONFIG_KVM) support with Virtual Function I/O feature (CONFIG_VFIO) enabled. This failure could occur if a malicious guest device sent a virtual interrupt (guest IRQ) with a larger (>1024) index value. (CVE-2017-1000252) - Linux kernel Virtualization Module (CONFIG_KVM) for the Intel processor family (CONFIG_KVM_INTEL) is vulnerable to a DoS issue. It could occur if a guest was to flood the I/O port 0x80 with write requests. A guest user could use this flaw to crash the host kernel resulting in DoS.

    Any user able to running 32-bit applications in a x86
    machine can disable ASLR by setting the RLIMIT_STACK
    resource to unlimited. (CVE-2016-3672)

  - 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

    function in the ALSA subsystem in the Linux kernel
    allows attackers to induce a kernel memory corruption
    and possibly crash or lock up a system. Due to the
    nature of the flaw, a privilege escalation cannot be
    fully ruled out, although we believe it is unlikely.
    (CVE-2017-0861)

  - A reachable assertion failure flaw was found in the
    Linux kernel built with KVM virtualisation(CONFIG_KVM)
    support with Virtual Function I/O feature (CONFIG_VFIO)
    enabled. This failure could occur if a malicious guest
    device sent a virtual interrupt (guest IRQ) with a
    larger (>1024) index value. (CVE-2017-1000252)

  - Linux kernel Virtualization Module (CONFIG_KVM) for the
    Intel processor family (CONFIG_KVM_INTEL) is vulnerable
    to a DoS issue. It could occur if a guest was to flood
    the I/O port 0x80 with write requests. A guest user
    could use this flaw to crash the host kernel resulting
    in DoS. (CVE-2017-1000407)

  - A flaw was found in the processing of incoming L2CAP
    bluetooth commands. Uninitialized stack variables can be
    sent to an attacker leaking data in kernel address
    space. (CVE-2017-1000410)

  - A race condition was found in the Linux kernel before
    version 4.11-rc1 in 'fs/timerfd.c' file which allows a
    local user to cause a kernel list corruption or use-
    after-free via simultaneous operations with a file
    descriptor which leverage improper 'might_cancel'
    queuing. An unprivileged local user could use this flaw
    to cause a denial of service of the system. Due to the
    nature of the flaw, privilege escalation cannot be fully
    ruled out, although we believe it is unlikely.
    (CVE-2017-10661)

  - Linux kernel built with the KVM visualization support
    (CONFIG_KVM), with nested visualization (nVMX) feature
    enabled (nested=1), is vulnerable to a crash due to
    disabled external interrupts. As L2 guest could access
    (r/w) hardware CR8 register of the host(L0). In a nested
    visualization setup, L2 guest user could use this flaw
    to potentially crash the host(L0) resulting in DoS.
    (CVE-2017-12154)

  - It was found that in the Linux kernel through v4.14-rc5,
    bio_map_user_iov() and bio_unmap_user() in 'block/bio.c'
    do unbalanced pages refcounting if IO vector has small
    consecutive buffers belonging to the same page.
    bio_add_pc_page() merges them into one, but the page
    reference is never dropped, causing a memory leak and
    possible system lockup due to out-of-memory condition.
    (CVE-2017-12190)

  - A flaw was found in the Linux kernel's implementation of
    valid_master_desc() in which a memory buffer would be
    compared to a userspace value with an incorrect size of
    comparison. By bruteforcing the comparison, an attacker
    could determine what was in memory after the description
    and possibly obtain sensitive information from kernel
    memory. (CVE-2017-13305)

  - A use-after-free vulnerability was found in a network
    namespaces code affecting the Linux kernel since
    v4.0-rc1 through v4.15-rc5. The function
    get_net_ns_by_id() 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)

  - A use-after-free vulnerability was found when issuing an
    ioctl to a sound device. This could allow a user to
    exploit a race condition and create memory corruption or
    possibly privilege escalation. (CVE-2017-15265)

  - A flaw was found in the implementation of associative
    arrays where the add_key systemcall and KEYCTL_UPDATE
    operations allowed for a NULL payload with a nonzero
    length. When accessing the payload within this length
    parameters value, an unprivileged user could trivially
    cause a NULL pointer dereference (kernel oops).
    (CVE-2017-15274)

  - The net/netfilter/nfnetlink_cthelper.c function in the
    Linux kernel through 4.14.4 does not require the
    CAP_NET_ADMIN capability for new, get, and del
    operations. This 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 __netlink_deliver_tap_skb function in
    net/netlink/af_netlink.c in the Linux kernel, through
    4.14.4, does not restrict observations of Netlink
    messages to a single net namespace, when CONFIG_NLMON is
    enabled. This 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. This allows local users
    to cause a denial of service, due to out-of-bounds write
    access, or possibly have unspecified other impact via a
    crafted USB device. Due to the nature of the flaw,
    privilege escalation cannot be fully ruled out, although
    we believe it is unlikely. (CVE-2017-17558)

  - The Salsa20 encryption algorithm in the Linux kernel,
    before 4.14.8, does not correctly handle zero-length
    inputs. This allows a local attacker the ability to use
    the AF_ALG-based skcipher interface to cause a denial of
    service (uninitialized-memory free and kernel crash) or
    have an unspecified other impact by executing a crafted
    sequence of system calls that use the blkcipher_walk
    API. Both the generic implementation
    (crypto/salsa20_generic.c) and x86 implementation
    (arch/x86/crypto/salsa20_glue.c) of Salsa20 are
    vulnerable. (CVE-2017-17805)

  - 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. Due to the nature of the flaw, privilege
    escalation cannot be fully ruled out, although we
    believe it is unlikely. (CVE-2017-18017)

  - The Linux kernel, before version 4.14.3, is vulnerable
    to a denial of service in
    drivers/md/dm.c:dm_get_from_kobject() which can be
    caused by local users leveraging a race condition with
    __dm_destroy() during creation and removal of DM
    devices. Only privileged local users (with CAP_SYS_ADMIN
    capability) can directly perform the ioctl operations
    for dm device creation and removal and this would
    typically be outside the direct control of the
    unprivileged attacker. (CVE-2017-18203)

  - The madvise_willneed function in the Linux kernel allows
    local users to cause a denial of service (infinite loop)
    by triggering use of MADVISE_WILLNEED for a DAX mapping.
    (CVE-2017-18208)

  - A flaw was found where the kernel truncated the value
    used to indicate the size of a buffer which it would
    later become zero using an untruncated value. This can
    corrupt memory outside of the original allocation.
    (CVE-2017-9725)

  - In the Linux kernel versions 4.12, 3.10, 2.6, and
    possibly earlier, a race condition vulnerability exists
    in the sound system allowing for a potential deadlock
    and memory corruption due to use-after-free condition
    and thus denial of service. Due to the nature of the
    flaw, privilege escalation cannot be fully ruled out,
    although we believe it is unlikely. (CVE-2018-1000004)

  - Improper validation in the bnx2x network card driver of
    the Linux kernel version 4.15 can allow for denial of
    service (DoS) attacks via a packet with a gso_size
    larger than ~9700 bytes. Untrusted guest VMs can exploit
    this vulnerability in the host machine, causing a crash
    in the network card. (CVE-2018-1000026)

  - By mmap()ing a FUSE-backed file onto a process's memory
    containing command line arguments (or environment
    strings), an attacker can cause utilities from psutils
    or procps (such as ps, w) or any other program which
    makes a read() call to the /proc//cmdline (or
    /proc//environ) files to block indefinitely (denial
    of service) or for some controlled time (as a
    synchronization primitive for other attacks).
    (CVE-2018-1120)

  - A null pointer dereference in dccp_write_xmit() function
    in net/dccp/output.c in the Linux kernel allows a local
    user to cause a denial of service by a number of certain
    crafted system calls. (CVE-2018-1130)

  - 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-2018-17972)

  - A flaw was found in the Linux kernel with files on tmpfs
    and hugetlbfs. An attacker is able to bypass file
    permissions on filesystems mounted with tmpfs/hugetlbs
    to modify a file and possibly disrupt normal system
    behavior. At this time there is an understanding there
    is no crash or privilege escalation but the impact of
    modifications on these filesystems of files in
    production systems may have adverse affects.
    (CVE-2018-18397)

  - In the Linux kernel before 4.17, a local attacker able
    to set attributes on an xfs filesystem could make this
    filesystem non-operational until the next mount by
    triggering an unchecked error condition during an xfs
    attribute change, because xfs_attr_shortform_addname in
    fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE
    operations with conversion of an attr from short to long
    form. (CVE-2018-18690)

  - Modern operating systems implement virtualization of
    physical memory to efficiently use available system
    resources and provide inter-domain protection through
    access control and isolation. The L1TF issue was found
    in the way the x86 microprocessor designs have
    implemented speculative execution of instructions (a
    commonly used performance optimization) in combination
    with handling of page-faults caused by terminated
    virtual to physical address resolving process. As a
    result, an unprivileged attacker could use this flaw to
    read privileged memory of the kernel or other processes
    and/or cross guest/host boundaries to read host memory
    by conducting targeted cache side-channel attacks.
    (CVE-2018-3646)

  - A flaw was found in the Linux kernel's handling of
    loopback devices. An attacker, who has permissions to
    setup loopback disks, may create a denial of service or
    other unspecified actions. (CVE-2018-5344)

  - 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)

  - An error in the _sctp_make_chunk() function
    (net/sctp/sm_make_chunk.c) when handling SCTP, packet
    length can be exploited by a malicious local user to
    cause a kernel crash and a DoS. (CVE-2018-5803)

  - In the function wmi_set_ie() in the Linux kernel the
    length validation code does not handle unsigned integer
    overflow properly. As a result, a large value of the
    ie_len argument can cause a buffer overflow and thus a
    memory corruption leading to a system crash or other or
    unspecified impact. Due to the nature of the flaw,
    privilege escalation cannot be fully ruled out, although
    we believe it is unlikely. (CVE-2018-5848)

  - 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 can reset the pool
    size manually via ioctl concurrently, and this may lead
    to UAF or out-of-bound access. (CVE-2018-7566)

  - A possible memory corruption due to a type confusion was
    found in the Linux kernel in the sk_clone_lock()
    function in the net/core/sock.c. The possibility of
    local escalation of privileges cannot be fully ruled out
    for a local unprivileged attacker. (CVE-2018-9568)

    NASL idEULEROS_SA-2019-1450.NASL
    descriptionAccording to the versions of the kvm package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - The msr_mtrr_valid function in arch/x86/kvm/mtrr.c in the Linux kernel before 4.6.1 supports MSR 0x2f8, which allows guest OS users to read or write to the kvm_arch_vcpu data structure, and consequently obtain sensitive information or cause a denial of service (system crash), via a crafted ioctl call.(CVE-2016-3713) - 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-2016-8630) - Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support was vulnerable to an incorrect segment selector(SS) value error. The error could occur while loading values into the SS register in long mode. A user or process inside a guest could use this flaw to crash the guest, resulting in DoS or potentially escalate their privileges inside the guest.(CVE-2017-2583) - arch/x86/kvm/emulate.c in the Linux kernel through 4.9.3 allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free) via a crafted application that leverages instruction emulation for fxrstor, fxsave, sgdt, and sidt.(CVE-2017-2584) - A reachable assertion failure flaw was found in the Linux kernel built with KVM virtualisation(CONFIG_KVM) support with Virtual Function I/O feature (CONFIG_VFIO) enabled. This failure could occur if a malicious guest device sent a virtual interrupt (guest IRQ) with a larger (i1/4z1024) index value.(CVE-2017-1000252) - An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor

    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - 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-2016-9754) - A flaw was found in the Linux kernel

    descriptionThe SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.90 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-1000252: The KVM subsystem in the Linux kernel allowed 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 (bnc#1058038). - CVE-2017-10810: Memory leak in the virtio_gpu_object_create function in drivers/gpu/drm/virtio/virtgpu_object.c in the Linux kernel allowed attackers to cause a denial of service (memory consumption) by triggering object-initialization failures (bnc#1047277). - CVE-2017-11472: The acpi_ns_terminate() function in drivers/acpi/acpica/nsutils.c in the Linux kernel did not flush the operand cache and causes a kernel stack dump, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table (bnc#1049580). - CVE-2017-11473: Buffer overflow in the mp_override_legacy_irq() function in arch/x86/kernel/acpi/boot.c in the Linux kernel allowed local users to gain privileges via a crafted ACPI table (bnc#1049603). - CVE-2017-12134: The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation (bnc#1051790 bnc#1053919). - CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request.

  • NASL familySuSE Local Security Checks
    NASL idOPENSUSE-2017-1160.NASL
    descriptionThe openSUSE Leap 42.3 kernel was updated to 4.4.90 to receive various security and bugfixes. The following security bugs were fixed : - CVE-2017-1000252: The KVM subsystem in the Linux kernel allowed 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 (bnc#1058038). - CVE-2017-14489: The iscsi_if_rx function in drivers/scsi/scsi_transport_iscsi.c in the Linux kernel allowed local users to cause a denial of service (panic) by leveraging incorrect length validation (bnc#1059051). - CVE-2017-12153: A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel This function did not check whether the required attributes are present in a Netlink request. This request can be issued by a user with the CAP_NET_ADMIN capability and may result in a NULL pointer dereference and system crash (bnc#1058410). - CVE-2017-12154: The prepare_vmcs02 function in arch/x86/kvm/vmx.c in the Linux kernel did not ensure that the

  • NASL familyNewStart CGSL Local Security Checks
    NASL idNEWSTART_CGSL_NS-SA-2019-0074_KERNEL-RT.NASL
    descriptionThe remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has kernel-rt packages installed that are affected by multiple vulnerabilities: - Integer overflow in the aio_setup_single_vector function in fs/aio.c in the Linux kernel 4.0 allows local users to cause a denial of service or possibly have unspecified other impact via a large AIO iovec. NOTE: this vulnerability exists because of a CVE-2012-6701 regression. (CVE-2015-8830) - A weakness was found in the Linux ASLR implementation. Any user able to running 32-bit applications in a x86 machine can disable ASLR by setting the RLIMIT_STACK resource to unlimited. (CVE-2016-3672) - 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. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2016-7913) - Use-after-free vulnerability in the snd_pcm_info() function in the ALSA subsystem in the Linux kernel allows attackers to induce a kernel memory corruption and possibly crash or lock up a system. Due to the nature of the flaw, a privilege escalation cannot be fully ruled out, although we believe it is unlikely. (CVE-2017-0861) - A reachable assertion failure flaw was found in the Linux kernel built with KVM virtualisation(CONFIG_KVM) support with Virtual Function I/O feature (CONFIG_VFIO) enabled. This failure could occur if a malicious guest device sent a virtual interrupt (guest IRQ) with a larger (>1024) index value. (CVE-2017-1000252) - Linux kernel Virtualization Module (CONFIG_KVM) for the Intel processor family (CONFIG_KVM_INTEL) is vulnerable to a DoS issue. It could occur if a guest was to flood the I/O port 0x80 with write requests. A guest user could use this flaw to crash the host kernel resulting in DoS. (CVE-2017-1000407) - A flaw was found in the processing of incoming L2CAP bluetooth commands. Uninitialized stack variables can be sent to an attacker leaking data in kernel address space. (CVE-2017-1000410) - A race condition was found in the Linux kernel before version 4.11-rc1 in
