   An update that solves 12 vulnerabilities and has 48 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-2018-14617: Prevent NULL pointer dereference and panic in
     hfsplus_lookup() when opening a file (that is purportedly a hard link)
     in an hfs+ filesystem that has malformed catalog data, and is mounted
     read-only without a metadata directory (bsc#1102870).
   - CVE-2018-16276: Incorrect bounds checking in the yurex USB driver in
     yurex_read allowed local attackers to use user access read/writes to
     crash the kernel or potentially escalate privileges (bsc#1106095).
   - CVE-2018-15594: Ensure correct handling of indirect calls, to prevent
     attackers for conducting Spectre-v2 attacks against paravirtual guests
     (bsc#1105348).
   - CVE-2018-14634: Prevent integer overflow in create_elf_tables that
     allowed a local attacker to exploit this vulnerability via a SUID-root
     binary and obtain full root privileges (bsc#1108912)
   - CVE-2018-12896: Prevent integer overflow in the POSIX timer code that
     was caused by the way the overrun accounting works. Depending on
     interval and expiry time values, the overrun can be larger than INT_MAX,
     but the accounting is int based. This basically made the accounting
     values, which are visible to user space via timer_getoverrun(2) and
     siginfo::si_overrun, random. This allowed a local user to cause a denial
     of service (signed integer overflow) via crafted mmap, futex,
     timer_create, and timer_settime system calls (bnc#1099922)
   - CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local
     attackers to use a incorrect bounds check in the CDROM driver
     CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)
   - CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status
     that could have been used by local attackers to read kernel memory
     (bnc#1107689)
   - CVE-2018-6555: The irda_setsockopt function allowed local users to cause
     a denial of service (ias_object use-after-free and system crash) or
     possibly have unspecified other impact via an AF_IRDA socket
     (bnc#1106511)
   - CVE-2018-6554: Prevent memory leak in the irda_bind function that
     allowed local users to cause a denial of service (memory consumption) by
     repeatedly binding an AF_IRDA socket (bnc#1106509)
   - CVE-2018-15572: The spectre_v2_select_mitigation function did not always
     fill RSB upon a context switch, which made it easier for attackers to
     conduct userspace-userspace spectreRSB attacks (bnc#1102517)
   - CVE-2018-10902: Protect against concurrent access to prevent double
     realloc (double free) in snd_rawmidi_input_params() and
     snd_rawmidi_output_status(). A malicious local attacker could have used
     this for privilege escalation (bnc#1105322)
   - CVE-2018-14734: ucma_leave_multicast accessed a certain data structure
     after a cleanup step in ucma_process_join, which allowed attackers to
     cause a denial
     of service (use-after-free) (bsc#1103119)
