Affected Products:
                    SUSE Linux Enterprise Real Time Extension 12-SP3

   An update that solves 15 vulnerabilities and has 58 fixes
   is now available.


   The SUSE Linux Enterprise 12 SP3 RT kernel was updated to 4.4.147 to
   receive various security and bugfixes.

   The following security bugs were fixed:

   - CVE-2017-18344: The timer_create syscall implementation in
     kernel/time/posix-timers.c didn't properly validate the
     sigevent->sigev_notify field, which leads to out-of-bounds access in the
     show_timer function (called when /proc/$PID/timers is read). This
     allowed userspace applications to read arbitrary kernel memory (on a
     (bnc#1102851 bsc#1103580).
   - CVE-2018-10876: A flaw was found in the ext4 filesystem code. A
     use-after-free was possible in ext4_ext_remove_space() function when
     mounting and operating a crafted ext4 image. (bnc#1099811)
   - CVE-2018-10877: The ext4 filesystem was vulnerable to an out-of-bound
     access in the ext4_ext_drop_refs() function when operating on a crafted
     ext4 filesystem image. (bnc#1099846)
   - CVE-2018-10878: A flaw was found in the ext4 filesystem. A local user
     could cause an out-of-bounds write and a denial of service or
     unspecified other impact is possible by mounting and operating a crafted
     ext4 filesystem image. (bnc#1099813)
   - CVE-2018-10879: A flaw was found in the ext4 filesystem. A local user
     could cause a use-after-free in ext4_xattr_set_entry function and a
     denial of service or unspecified other impact may occur by renaming a
     file in a crafted ext4 filesystem image. (bnc#1099844)
   - CVE-2018-10880: Linux kernel is vulnerable to a stack-out-of-bounds
     write in the ext4 filesystem code when mounting and writing to a crafted
     ext4 image in ext4_update_inline_data(). An attacker could use this to
     cause a system crash and a denial of service. (bnc#1099845)
   - CVE-2018-10881: A flaw was found in the ext4 filesystem. A local user
     can cause an out-of-bound access in ext4_get_group_info function, a
     denial of service, and a system crash by mounting and operating on a
     crafted ext4 filesystem image. (bnc#1099864)
   - CVE-2018-10882: A flaw was found in the ext4 filesystem. A local user
     can cause an out-of-bound write in in fs/jbd2/transaction.c code, a
     denial of service, and a system crash by unmounting a crafted ext4
     filesystem image. (bnc#1099849)
   - CVE-2018-10883: A flaw was found in the ext4 filesystem. A local user
     can cause an out-of-bounds write in jbd2_journal_dirty_metadata(), a
     denial of service, and a system crash by mounting and operating on a
     crafted ext4 filesystem image. (bnc#1099863)
   - CVE-2018-14734: drivers/infiniband/core/ucma.c allowed
     ucma_leave_multicast to access a certain data structure after a cleanup
     step in ucma_process_join, which allowed attackers to cause a denial of
     service (use-after-free) (bnc#1103119).
   - CVE-2018-3620: Systems with microprocessors utilizing speculative
     execution and address translations may allow unauthorized disclosure of
     information residing in the L1 data cache to an attacker with local user
     access via a terminal page fault and a side-channel analysis
   - CVE-2018-3646: Systems with microprocessors utilizing speculative
     execution and address translations may allow unauthorized disclosure of
     information residing in the L1 data cache to an attacker with local user
     access with guest OS privilege via a terminal page fault and a
     side-channel analysis (bnc#1089343 bnc#1104365).
   - CVE-2018-5390: The Linux kernel could be forced to make very expensive
     calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every
     incoming packet which can lead to a denial of service (bnc#1102340).
   - CVE-2018-5391 aka "FragmentSmack": A flaw in the IP packet reassembly
     could be used by remote attackers to consume lots of CPU time
   - CVE-2018-9363: A buffer overflow in bluetooth HID report processing
     could be used by malicious bluetooth devices to crash the kernel or
     potentially execute code (bnc#1105292).
