Summary

A security flaw was discovered in the nl80211_set_rekey_data() function in net/wireless/nl80211.c in the Linux kernel through 4.13.3. This function does 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.

    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

    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

  - 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.

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2017-7482 Shi Lei discovered that RxRPC Kerberos 5 ticket handling code does not properly verify metadata, leading to information disclosure, denial of service or potentially execution of arbitrary code. CVE-2017-7542 An integer overflow vulnerability in the ip6_find_1stfragopt() function was found allowing a local attacker with privileges to open raw sockets to cause a denial of service. CVE-2017-7889 Tommi Rantala and Brad Spengler reported that the mm subsystem does not properly enforce the CONFIG_STRICT_DEVMEM protection mechanism, allowing a local attacker with access to /dev/mem to obtain sensitive information or potentially execute arbitrary code. CVE-2017-10661 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 to execute arbitrary code. CVE-2017-10911 / XSA-216 Anthony Perard of Citrix discovered an information leak flaw in Xen blkif response handling, allowing a malicious unprivileged guest to obtain sensitive information from the host or other guests. CVE-2017-11176 It was discovered that the mq_notify() function does not set the sock pointer to NULL upon entry into the retry logic. An attacker can take advantage of this flaw during a userspace close of a Netlink socket to cause a denial of service or potentially cause other impact. 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. Sch&ouml;nherr 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-2017-12153 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 on a system 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 of Google reported that a specific sequence of operations on a TCP socket could lead to division by zero. A local user could use this for denial of service. CVE-2017-14140 Otto Ebeling reported that the move_pages() system call permitted users to discover the memory layout of a set-UID process running under their real user-ID. This made it easier for local users to exploit vulnerabilities in programs installed with the set-UID permission bit set. CVE-2017-14156

    NASL idSUSE_SU-2017-2908-1.NASL
    descriptionThe SUSE Linux Enterprise 12 SP1 LTS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : - 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). - 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#1063667). - CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not consider the case of a NULL payload in conjunction with a nonzero length value, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call, a different vulnerability than CVE-2017-12192 (bnc#1045327). - CVE-2017-15265: Use-after-free vulnerability in the Linux kernel allowed local users to have unspecified impact via vectors related to /dev/snd/seq (bnc#1062520). - CVE-2017-1000365: The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIM_INFINITY (1/4 of the size), but did not take the argument and environment pointers into account, which allowed attackers to bypass this limitation. (bnc#1039354). - 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
