   An update that solves 14 vulnerabilities and has 15 fixes
   is now available.

Description:


   The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2018-5848: In the function wmi_set_ie(), the length validation code
     did not handle unsigned integer overflow properly. As a result, a large
     value of the 'ie_len' argument could have caused a buffer overflow
     (bnc#1097356)
   - CVE-2018-1000204: Prevent infoleak caused by incorrect handling of the
     SG_IO ioctl (bsc#1096728).
   - CVE-2017-18249: The add_free_nid function did not properly track an
     allocated nid, which allowed local users to cause a denial of service
     (race condition) or possibly have unspecified other impact via
     concurrent threads (bnc#1087036)
   - CVE-2018-3665: Prevent disclosure of FPU registers (including XMM and
     AVX registers) between processes. These registers might contain
     encryption keys when doing SSE accelerated AES enc/decryption
     (bsc#1087086)
   - CVE-2017-18241: Prevent a NULL pointer dereference by using a
     noflush_merge
     option that triggers a NULL value for a flush_cmd_control data structure
      (bnc#1086400)
   - CVE-2017-13305: Prevent information disclosure vulnerability in
     encrypted-keys (bsc#1094353).
   - CVE-2018-1093: The ext4_valid_block_bitmap function allowed attackers to
     cause a denial of service (out-of-bounds read and system crash) via a
     crafted ext4 image because balloc.c and ialloc.c did not validate bitmap
     block numbers (bsc#1087095).
   - CVE-2018-1094: The ext4_fill_super function did not always initialize
     the crc32c checksum driver, which allowed attackers to cause a denial of
     service (ext4_xattr_inode_hash NULL pointer dereference and system
     crash) via a crafted ext4 image (bsc#1087007).
   - CVE-2018-1092: The ext4_iget function mishandled the case of a root
     directory with a zero i_links_count, which allowed attackers to cause a
     denial of service (ext4_process_freed_data NULL pointer dereference and
     OOPS) via a crafted ext4 image (bsc#1087012).
   - CVE-2018-1130: NULL pointer dereference in dccp_write_xmit() function
     that allowed a local user to cause a denial of service by a number of
     certain crafted system calls (bsc#1092904).
   - CVE-2018-1065: The netfilter subsystem mishandled the case of a rule
     blob that contains a jump but lacks a user-defined chain, which allowed
     local users to cause a denial of service (NULL pointer dereference) by
     leveraging the CAP_NET_RAW or CAP_NET_ADMIN capability (bsc#1083650).
   - CVE-2018-5803: Prevent error in the "_sctp_make_chunk()" function when
     handling SCTP packets length that could have been exploited to cause a
     kernel crash (bnc#1083900).
   - CVE-2018-7492: Prevent NULL pointer dereference in the net/rds/rdma.c
     __rds_rdma_map() function that allowed local attackers to cause a system
     panic and a denial-of-service, related to RDS_GET_MR and
     RDS_GET_MR_FOR_DEST (bsc#1082962).
   - CVE-2018-1000199: Prevent vulnerability in modify_user_hw_breakpoint()
     that could have caused a crash and possibly memory corruption
     (bsc#1089895).

   The following non-security bugs were fixed:

   - ALSA: timer: Fix pause event notification (bsc#973378).
   - Fix excessive newline in /proc/*/status (bsc#1094823).
   - Fix the patch content (bsc#1085185)
   - KVM: x86: Sync back MSR_IA32_SPEC_CTRL to VCPU data structure
     (bsc#1096242, bsc#1096281).
   - Revert "bs-upload-kernel: do not set %opensuse_bs" This reverts commit
     e89e2b8cbef05df6c874ba70af3cb4c57f82a821.
   - ipv6: add mtu lock check in __ip6_rt_update_pmtu (bsc#1092552).
   - ipv6: omit traffic class when calculating flow hash (bsc#1095042).
   - kgraft/bnx2fc: Do not block kGraft in bnx2fc_l2_rcv kthread
     (bsc#1094033).
   - mm, page_alloc: do not break __GFP_THISNODE by zonelist reset
     (bsc#1079152, VM Functionality).
   - x86/boot: Fix early command-line parsing when partial word matches
     (bsc#1096140).
   - x86/bugs: IBRS: make runtime disabling fully dynamic (bsc#1096281).
   - x86/bugs: Respect retpoline command line option (bsc#1068032).
   - x86/bugs: correctly force-disable IBRS on !SKL systems (bsc#1092497).
   - x86/bugs: spec_ctrl must be cleared from cpu_caps_set when being
     disabled (bsc#1096140).
   - x86/kaiser: export symbol kaiser_set_shadow_pgd() (bsc#1092813)
   - xfs: convert XFS_AGFL_SIZE to a helper function (bsc#1090955,
     bsc#1090534).
   - xfs: detect agfl count corruption and reset agfl (bsc#1090955,
     bsc#1090534).
   - xfs: do not log/recover swapext extent owner changes for deleted inodes
     (bsc#1090955).
