"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."
