______________________________________________________________________________

An update that solves 7 vulnerabilities and has 9 fixes is now available.

Description:


The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security
and bugfixes.
The following security bugs were fixed:

  o CVE-2019-14284: The drivers/block/floppy.c allowed a denial of service by
    setup_format_params division-by-zero. Two consecutive ioctls can trigger
    the bug: the first one should set the drive geometry with .sect and .rate
    values that make F_SECT_PER_TRACK be zero. Next, the floppy format
    operation should be called. It can be triggered by an unprivileged local
    user even when a floppy disk has not been inserted. NOTE: QEMU creates the
    floppy device by default (bsc#1143189).
  o CVE-2019-14283: The function set_geometry in drivers/block/floppy.c did not
    validate the sect and head fields, as demonstrated by an integer overflow
    and out-of-bounds read. It can be triggered by an unprivileged local user
    when a floppy disk has been inserted. NOTE: QEMU creates the floppy device
    by default (bsc#1143191).
  o CVE-2019-13631: In parse_hid_report_descriptor in drivers/input/tablet/
    gtco.c, a malicious USB device can send an HID report that triggers an
    out-of-bounds write during generation of debugging messages (bsc#1142023).
  o CVE-2019-11810: A NULL pointer dereference can occur when
    megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/
    megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a
    use-after-free (bsc#1134399).
  o CVE-2019-1125: Enable Spectre v1 swapgs mitigations (bsc#1139358).
  o CVE-2018-20855: An issue was discovered in create_qp_common in drivers/
    infiniband/hw/mlx5/qp.c, mlx5_ib_create_qp_resp was never initialized,
    resulting in a leak of stack memory to userspace (bsc#1143045).
  o CVE-2015-9289: A buffer overflow occurs when checking userspace params in
    drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC
    command is 6, according to the userspace API. However, the code allowed
    larger values such as 23 (bsc#1143179).


The following non-security bugs were fixed:

  o fix detection of race between fcntl-setlk and close (bsc#1140965).
  o ocfs2: add first lock wait time in locking_state (bsc#1134390).
  o ocfs2: add last unlock times in locking_state (bsc#1134390).
  o ocfs2: add locking filter debugfs file (bsc#1134390).
  o powerpc/watchpoint: Restore NV GPRs while returning from exception

(bsc#1140945,bsc#1141401,bsc#1141402,bsc#1141452,bsc#1141453,bsc#1141454).
xen-netfront: use napi_complete() correctly to prevent Rx stalling (bsc#
1138744).
