"The openSUSE Leap 42.2 kernel was updated to 4.4.87 to receive various
security and bugfixes.

The following security bugs were fixed :

  - CVE-2017-1000251: The native Bluetooth stack in the
    Linux Kernel (BlueZ) was vulnerable to a stack overflow
    vulnerability in the processing of L2CAP configuration
    responses resulting in Remote code execution in kernel
    space (bnc#1057389).

  - 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-2017-11472: 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-2017-14051: 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-2017-12134: 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 1053919).
