    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)

    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,

    "According to the versions of the kernel packages installed, the
    EulerOS Virtualization installation on the remote host is affected by
    the following vulnerabilities :
    
      - The snd_timer_interrupt function in sound/core/timer.c
        in the Linux kernel before 4.4.1 does not properly
        maintain a certain linked list, which allows local
        users to cause a denial of service (race condition and
        system crash) via a crafted ioctl call.(CVE-2016-2545)
    
      - sound/core/timer.c in the Linux kernel before 4.4.1
        uses an incorrect type of mutex, which allows local
        users to cause a denial of service (race condition,
        use-after-free, and system crash) via a crafted ioctl
        call.(CVE-2016-2546)
    
      - sound/core/timer.c in the Linux kernel before 4.4.1
        employs a locking approach that does not consider slave
        timer instances, which allows local users to cause a
        denial of service (race condition, use-after-free, and
        system crash) via a crafted ioctl call.(CVE-2016-2547)
    
      - sound/core/timer.c in the Linux kernel before 4.4.1
        retains certain linked lists after a close or stop
        action, which allows local users to cause a denial of
        service (system crash) via a crafted ioctl call,
        related to the (1) snd_timer_close and (2)
        _snd_timer_stop functions.(CVE-2016-2548)
    
      - sound/core/hrtimer.c in the Linux kernel before 4.4.1
        does not prevent recursive callback access, which
        allows local users to cause a denial of service
        (deadlock) via a crafted ioctl call.(CVE-2016-2549)
    
      - A resource-exhaustion vulnerability was found in the
        kernel, where an unprivileged process could allocate
        and accumulate far more file descriptors than the
        process' limit. A local, unauthenticated user could
        exploit this flaw by sending file descriptors over a
        Unix socket and then closing them to keep the process'
        fd count low, thereby creating kernel-memory or
        file-descriptors exhaustion (denial of
        service).(CVE-2016-2550)
    
      - It is possible for a single process to cause an OOM
        condition by filling large pipes with data that are
        never read. A typical process filling 4096 pipes with 1
        MB of data will use 4 GB of memory and there can be
        multiple such processes, up to a
        per-user-limit.(CVE-2016-2847)
    
      - A security flaw was found in the Linux kernel that an
        attempt to move page mapped by AIO ring buffer to the
        other node triggers NULL pointer dereference at
        trace_writeback_dirty_page(), because
        aio_fs_backing_dev_info.dev is 0.(CVE-2016-3070)
    
      - 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-2016-3134)
    
      - An integer overflow vulnerability was found in the
        Linux kernel in xt_alloc_table_info, which on 32-bit
        systems can lead to small structure allocation and a
        copy_from_user based heap corruption.(CVE-2016-3135)
    
      - 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-2016-3136)
    
      - drivers/usb/serial/cypress_m8.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 USB device without both an
        interrupt-in and an interrupt-out endpoint descriptor,
        related to the cypress_generic_port_probe and
        cypress_open functions.(CVE-2016-3137)
    
      - The acm_probe function in drivers/usb/class/cdc-acm.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 USB device
        without both a control and a data endpoint
        descriptor.(CVE-2016-3138)
    
      - The wacom_probe function in
        drivers/input/tablet/wacom_sys.c in the Linux kernel
        before 3.17 allows physically proximate attackers to
        cause a denial of service (NULL pointer dereference and
        system crash) via a crafted endpoints value in a USB
        device descriptor.(CVE-2016-3139)
    
      - The digi_port_init function in
        drivers/usb/serial/digi_acceleport.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 endpoints
        value in a USB device descriptor.(CVE-2016-3140)
    
      - 'A security flaw was found in the Linux kernel's
        networking subsystem that destroying the network
        interface with huge number of ipv4 addresses assigned
        keeps ''rtnl_lock'' spinlock for a very long time (up
        to hour). This blocks many network-related operations,
        including creation of new incoming ssh connections.
    
      - The problem is especially important for containers, as
        the container owner has enough permissions to trigger
        this and block a network access on a whole host,
        outside the container.(CVE-2016-3156)'
    
      - 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 ims_pcu_parse_cdc_data function in
        drivers/input/misc/ims-pcu.c in the Linux kernel before
        4.5.1 allows physically proximate attackers to cause a
        denial of service (system crash) via a USB device
        without both a master and a slave
        interface.(CVE-2016-3689)
    
      - 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)
    
      - The usbip_recv_xbuff function in
        drivers/usb/usbip/usbip_common.c in the Linux kernel
        before 4.5.3 allows remote attackers to cause a denial
        of service (out-of-bounds write) or possibly have
        unspecified other impact via a crafted length value in
        a USB/IP packet.(CVE-2016-3955)
    
      - A flaw was found in the Linux kernel's keyring handling
        code: the key_reject_and_link() function could be
        forced to free an arbitrary memory block. An attacker
        could use this flaw to trigger a use-after-free
        condition on the system, potentially allowing for
        privilege escalation.(CVE-2016-4470)
    
      - 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-2016-4482)
    
      - A flaw was found in the way certain interfaces of the
        Linux kernel's Infiniband subsystem used write() as
        bi-directional ioctl() replacement, which could lead to
        insufficient memory security checks when being invoked
        using the splice() system call. A local unprivileged
        user on a system with either Infiniband hardware
        present or RDMA Userspace Connection Manager Access
        module explicitly loaded, could use this flaw to
        escalate their privileges on the system.(CVE-2016-4565)

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel before 4.7.1 allows local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed.(CVE-2016-7910) - Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel before 4.6.6 allows local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call.(CVE-2016-7911) - The assoc_array_insert_into_terminal_node function in lib/assoc_array.c in the Linux kernel before 4.5.3 does not check whether a slot is a leaf, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and out-of-bounds read) via an application that uses associative-array data structures, as demonstrated by the keyutils test suite.(CVE-2016-7914) - The IPv6 stack in the Linux kernel before 4.3.3 mishandles options data, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call.(CVE-2016-3841) - Race condition in the environ_read function in fs/proc/base.c in the Linux kernel before 4.5.4 allows local users to obtain sensitive information from kernel memory by reading a /proc/*/environ file during a process-setup time interval in which environment-variable copying is incomplete.(CVE-2016-7916) Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    "According to the versions of the kernel packages installed, the
    EulerOS installation on the remote host is affected by the following
    vulnerabilities :
    
      - Use-after-free vulnerability in the disk_seqf_stop
        function in block/genhd.c in the Linux kernel before
        4.7.1 allows local users to gain privileges by
        leveraging the execution of a certain stop operation
        even if the corresponding start operation had
        failed.(CVE-2016-7910)
    
      - Race condition in the get_task_ioprio function in
        block/ioprio.c in the Linux kernel before 4.6.6 allows
        local users to gain privileges or cause a denial of
        service (use-after-free) via a crafted ioprio_get
        system call.(CVE-2016-7911)
    
      - The assoc_array_insert_into_terminal_node function in
        lib/assoc_array.c in the Linux kernel before 4.5.3 does
        not check whether a slot is a leaf, which allows local
        users to obtain sensitive information from kernel
        memory or cause a denial of service (invalid pointer
        dereference and out-of-bounds read) via an application
        that uses associative-array data structures, as
        demonstrated by the keyutils test suite.(CVE-2016-7914)
    
      - The IPv6 stack in the Linux kernel before 4.3.3
        mishandles options data, which allows local users to
        gain privileges or cause a denial of service
        (use-after-free and system crash) via a crafted sendmsg
        system call.(CVE-2016-3841)
    
      - Race condition in the environ_read function in
        fs/proc/base.c in the Linux kernel before 4.5.4 allows
        local users to obtain sensitive information from kernel
        memory by reading a /proc/*/environ file during a
        process-setup time interval in which
        environment-variable copying is
        incomplete.(CVE-2016-7916)

    "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 snd_msndmidi_input_read function in
        sound/isa/msnd/msnd_midi.c in the Linux kernel through
        4.11.7 allows local users to cause a denial of service
        (over-boundary access) or possibly have unspecified
        other impact by changing the value of a message queue
        head pointer between two kernel reads of that value,
        aka a 'double fetch' vulnerability.(CVE-2017-9985i1/4%0
    
      - An assertion failure issue was found in the Linux
        kernel's KVM hypervisor module built to support
        visualization on ARM64 architecture platforms. The
        failure could occur while accessing Performance
        Monitors Cycle Count Register (PMCCNTR) from a guest. A
        privileged guest user could use this flaw to crash the
        host kernel resulting in denial of
        service.(CVE-2017-12168i1/4%0
    
      - The iscsi_if_rx() function in
        'drivers/scsi/scsi_transport_iscsi.c' in the Linux
        kernel from v2.6.24-rc1 through 4.13.2 allows local
        users to cause a denial of service (a system panic) by
        making a number of certain syscalls by leveraging
        incorrect length validation in the kernel
        code.(CVE-2017-14489i1/4%0
    
      - The hdpvr_probe function in
        drivers/media/usb/hdpvr/hdpvr-core.c in the Linux
        kernel through 4.13.11 allows 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.(CVE-2017-16644i1/4%0
    
      - The dvb frontend management subsystem in the Linux
        kernel contains a use-after-free which can allow a
        malicious user to write to memory that may be assigned
        to another kernel structure. This could create memory
        corruption, panic, or possibly other side
        affects.(CVE-2017-16648i1/4%0
    
      - 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-2016-3841i1/4%0
    
      - A flaw was found in the Linux kernel's ext4 filesystem.
        A local user can cause a use-after-free in
        ext4_xattr_set_entry function and a denial of service
        or unspecified other impact may occur by renaming a
        file in a crafted ext4 filesystem
        image.(CVE-2018-10879i1/4%0
    
      - A race condition was found in the Linux kernel, present
        since v3.14-rc1 through v4.12. The race happens between
        threads of inotify_handle_event() and vfs_rename()
        while running the rename operation against the same
        file. As a result of the race the next slab data or the
        slab's free list pointer can be corrupted with
        attacker-controlled data, which may lead to the
        privilege escalation.(CVE-2017-7533i1/4%0
    
      - A privilege-escalation vulnerability was discovered in
        the Linux kernel built with User Namespace
        (CONFIG_USER_NS) support. The flaw occurred when the
        ptrace() system call was used on a root-owned process
        to enter a user namespace. A privileged namespace user
        could exploit this flaw to potentially escalate their
        privileges on the system, outside the original
        namespace.(CVE-2015-8709i1/4%0
    
      - Use-after-free vulnerability in
        drivers/net/ppp/ppp_generic.c in the Linux kernel
        before 4.5.2 allows local users to cause a denial of
        service (memory corruption and system crash, or
        spinlock) or possibly have unspecified other impact by
        removing a network namespace, related to the
        ppp_register_net_channel and ppp_unregister_channel
        functions.(CVE-2016-4805i1/4%0
    
      - 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-2014-3601i1/4%0
    
      - A flaw was found in the Linux kernel's implementation
        of associative arrays introduced in 3.13. This
        functionality was backported to the 3.10 kernels in Red
        Hat Enterprise Linux 7. The flaw involved a null
        pointer dereference in assoc_array_apply_edit() due to
        incorrect node-splitting in assoc_array implementation.
        This affects the keyring key type and thus key addition
        and link creation operations may cause the kernel to
        panic.(CVE-2017-12193i1/4%0
    
      - Multiple race conditions in drivers/char/adsprpc.c and
        drivers/char/adsprpc_compat.c in the ADSPRPC driver for
        the Linux kernel 3.x, as used in Qualcomm Innovation
        Center (QuIC) Android contributions for MSM devices and
        other products, allow attackers to cause a denial of
        service (zero-value write) or possibly have unspecified
        other impact via a COMPAT_FASTRPC_IOCTL_INVOKE_FD ioctl
        call.(CVE-2015-0572i1/4%0
    
      - The sanity_check_ckpt function in fs/f2fs/super.c in
        the Linux kernel before version 4.12.4 does not
        validate the blkoff and segno arrays. This allows an
        unprivileged, local user to cause a system panic and
        DoS. Due to the nature of the flaw, privilege
        escalation cannot be fully ruled out, although we
        believe it is unlikely.(CVE-2017-10663i1/4%0
    
      - A stack overflow flaw caused by infinite recursion was
        found in the way the Linux kernel's Universal Disk
        Format (UDF) file system implementation processed
        indirect Information Control Blocks (ICBs). An attacker
        with physical access to the system could use a
        specially crafted UDF image to crash the
        system.(CVE-2014-6410i1/4%0
    
      - Race condition in the ion_ioctl function in
        drivers/staging/android/ion/ion.c in the Linux kernel
        before 4.6 allows local users to gain privileges or
        cause a denial of service (use-after-free) by calling
        ION_IOC_FREE on two CPUs at the same
        time.(CVE-2016-9120i1/4%0
    
      - drivers/hid/hid-picolcd_core.c in the Human Interface
        Device (HID) subsystem in the Linux kernel through
        3.11, when CONFIG_HID_PICOLCD is enabled, allows
        physically proximate attackers to cause a denial of
        service (NULL pointer dereference and OOPS) via a
        crafted device.(CVE-2013-2899i1/4%0
    
      - A flaw was found in the Linux kernel's implementation
        of overlayfs. An attacker can leak file resources in
        the system by opening a large file with write
        permissions on a overlay filesystem that is
        insufficient to deal with the size of the write.When
        unmounting the underlying device, the system is unable
        to free an inode and this will consume resources.
        Repeating this for all available inodes and memory will
        create a denial of service situation.(CVE-2015-8953i1/4%0
    
      - Buffer overflow in the mp_override_legacy_irq()
        function in arch/x86/kernel/acpi/boot.c in the Linux
        kernel through 4.12.2 allows local users to gain
        privileges via a crafted ACPI table.(CVE-2017-11473i1/4%0
    
      - Use-after-free vulnerability in the
        kvm_ioctl_create_device function in virt/kvm/kvm_main.c
        in the Linux kernel before 4.8.13 allows host OS users
        to cause a denial of service (host OS crash) or
        possibly gain privileges via crafted ioctl calls on the
        /dev/kvm device.(CVE-2016-10150i1/4%0

    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

    descriptionThe SUSE Linux Enterprise 11 SP2 LTSS kernel was updated to receive various security and bugfixes. This is the last planned LTSS kernel update for the SUSE Linux Enterprise Server 11 SP2 LTSS. The following security bugs were fixed : - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710). - CVE-2004-0230: TCP, when using a large Window Size, made it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP (bnc#969340). - CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the Linux kernel did not validate the relationship between the minimum fragment length and the maximum packet size, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831). - CVE-2016-8399: An out of bounds read in the ping protocol handler could have lead to information disclosure (bsc#1014746). - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531). - CVE-2012-6704: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUF or (2) SO_RCVBUF option (bnc#1013542). - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux kernel did not properly initialize Code Segment (CS) in certain error cases, which allowed local users to obtain sensitive information from kernel stack memory via a crafted application (bnc#1013038). - CVE-2016-3841: The IPv6 stack in the Linux kernel mishandled options data, which allowed local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call (bnc#992566). - CVE-2016-9685: Multiple memory leaks in error paths in fs/xfs/xfs_attr_list.c in the Linux kernel allowed local users to cause a denial of service (memory consumption) via crafted XFS filesystem operations (bnc#1012832). - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecified removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939). - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501). - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel lacked chunk-length checking for the first chunk, which allowed remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data (bnc#1011685). - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel allowed local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed (bnc#1010716). - CVE-2016-7911: Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call (bnc#1010711). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-7916: Race condition in the environ_read function in fs/proc/base.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a /proc/*/environ file during a process-setup time interval in which environment-variable copying is incomplete (bnc#1010467). - CVE-2016-8646: The hash_accept function in crypto/algif_hash.c in the Linux kernel allowed local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data (bnc#1010150). - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833). - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel used an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517). - CVE-2016-7097: The filesystem implementation in the Linux kernel preserves the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bnc#995968). - CVE-2017-5551: The filesystem implementation in the Linux kernel preserves the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions. This CVE tracks the fix for the tmpfs filesystem. (bsc#1021258). - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925). - CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077). - CVE-2016-0823: The pagemap_open function in fs/proc/task_mmu.c in the Linux kernel allowed local users to obtain sensitive physical-address information by reading a pagemap file, aka Android internal bug 25739721 (bnc#994759). - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932). - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in the Linux kernel did not properly maintain certain SACK state after a failed data copy, which allowed local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option (bnc#994296). - CVE-2016-6480: Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a

    descriptionThe SUSE Linux Enterprise 11 SP3 LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - CVE-2015-8970: crypto/algif_skcipher.c in the Linux kernel did not verify that a setkey operation has been performed on an AF_ALG socket before an accept system call is processed, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted application that did not supply a key, related to the lrw_crypt function in crypto/lrw.c (bnc#1008374). - CVE-2017-5551: Clear S_ISGID on tmpfs when setting posix ACLs (bsc#1021258). - CVE-2016-7097: The filesystem implementation in the Linux kernel preserves the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bnc#995968). - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bnc#1017710). - CVE-2004-0230: TCP, when using a large Window Size, made it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP (bnc#969340). - CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the Linux kernel did not validate the relationship between the minimum fragment length and the maximum packet size, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831). - CVE-2016-8399: An elevation of privilege vulnerability in the kernel networking subsystem could have enabled a local malicious application to execute arbitrary code within the context of the kernel bnc#1014746). - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531). - CVE-2012-6704: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUF or (2) SO_RCVBUF option (bnc#1013542). - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux kernel did not properly initialize Code Segment (CS) in certain error cases, which allowed local users to obtain sensitive information from kernel stack memory via a crafted application (bnc#1013038). - CVE-2016-3841: The IPv6 stack in the Linux kernel mishandled options data, which allowed local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call (bnc#992566). - CVE-2016-9685: Multiple memory leaks in error paths in fs/xfs/xfs_attr_list.c in the Linux kernel allowed local users to cause a denial of service (memory consumption) via crafted XFS filesystem operations (bnc#1012832). - CVE-2015-1350: The VFS subsystem in the Linux kernel provided an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939). - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501). - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel lacked chunk-length checking for the first chunk, which allowed remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data (bnc#1011685). - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel allowed local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed (bnc#1010716). - CVE-2016-7911: Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call (bnc#1010711). - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507). - CVE-2016-7916: Race condition in the environ_read function in fs/proc/base.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a /proc/*/environ file during a process-setup time interval in which environment-variable copying is incomplete (bnc#1010467). - CVE-2016-8646: The hash_accept function in crypto/algif_hash.c in the Linux kernel allowed local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data (bnc#1010150). - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel in certain unusual hardware configurations allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833). - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux, when the GNU Compiler Collection (gcc) stack protector is enabled, used an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517). - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925). - CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077). - CVE-2016-0823: The pagemap_open function in fs/proc/task_mmu.c in the Linux kernel allowed local users to obtain sensitive physical-address information by reading a pagemap file (bnc#994759). - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932). - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in the Linux kernel did not properly maintain certain SACK state after a failed data copy, which allowed local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option (bnc#994296). 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.

    descriptionAn update for kernel is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. 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 reporting emulation failures to user space could lead to either a local (CVE-2014-7842) or a L2->L1 (CVE-2010-5313) denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain systems, HPET is mapped to userspace as part of vdso (vvar) and thus an unprivileged user may generate MMIO transactions (and enter the emulator) this way. (CVE-2010-5313, CVE-2014-7842, Moderate) * It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system. (CVE-2013-4312, Moderate) * A buffer overflow flaw was found in the way the Linux kernel
