       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:
    
       - 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).
       - 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).
       - 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).
       - 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).
       - CVE-2019-1125: Enable Spectre v1 swapgs mitigations (bsc#1139358).
       - 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).
       - 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:
    
       - fix detection of race between fcntl-setlk and close (bsc#1140965).
       - ocfs2: add first lock wait time in locking_state (bsc#1134390).
       - ocfs2: add last unlock times in locking_state (bsc#1134390).
       - ocfs2: add locking filter debugfs file (bsc#1134390).
       - 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).
