   An update that solves 13 vulnerabilities and has 18 fixes
   is now available.

Description:



   The SUSE Linux Enterprise 11 SP4 RT kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2016-8405: An information disclosure vulnerability in kernel
     components including the ION subsystem, Binder, USB driver and
     networking subsystem could enable a local malicious application to
     access data outside of its permission levels. (bnc#1099942).
   - CVE-2017-13305: A information disclosure vulnerability was fixed in the
     encrypted-keys handling. (bnc#1094353).
   - CVE-2018-1000204: A malformed SG_IO ioctl issued for a SCSI device lead
     to a local kernel data leak manifesting in up to approximately 1000
     memory pages copied to the userspace. The problem has limited scope as
     non-privileged users usually have no permissions to access SCSI device
     files. (bnc#1096728).
   - CVE-2018-1068: A flaw was found in the implementation of 32-bit syscall
     interface for bridging. This allowed a privileged user to arbitrarily
     write to a limited range of kernel memory (bnc#1085107).
   - CVE-2018-1130: Linux kernel was vulnerable to a null pointer dereference
     in dccp_write_xmit() function in net/dccp/output.c in that allowed a
     local user to cause a denial of service by a number of certain crafted
     system calls (bnc#1092904).
   - CVE-2018-12233: In the ea_get function in fs/jfs/xattr.c a memory
     corruption bug in JFS could be triggered by calling setxattr twice with
     two different extended attribute names on the same file. This
     vulnerability can be triggered by an unprivileged user with the ability
     to create files and execute programs. A kmalloc call is incorrect,
     leading to slab-out-of-bounds in jfs_xattr (bnc#1097234).
   - CVE-2018-13053: The alarm_timer_nsleep function in
     kernel/time/alarmtimer.c had an integer overflow via a large relative
     timeout because ktime_add_safe is not used (bnc#1099924).
   - CVE-2018-13406: An integer overflow in the uvesafb_setcmap function in
     drivers/video/fbdev/uvesafb.c could result in local attackers being able
     to crash the kernel or potentially elevate privileges because
     kmalloc_array is not used (bnc#1098016 bnc#1100418).
   - 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
     (bnc#1087081).
   - 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-2018-5803: An error in the "_sctp_make_chunk()" function
     (net/sctp/sm_make_chunk.c) when handling SCTP packets length could be
     exploited to cause a kernel crash (bnc#1083900).
   - CVE-2018-5814: Multiple race condition errors when handling probe,
     disconnect, and rebind operations can be exploited to trigger a
     use-after-free condition or a NULL pointer dereference by sending
     multiple USB over IP packets (bnc#1096480).
   - CVE-2018-7492: A NULL pointer dereference was found in the
     net/rds/rdma.c __rds_rdma_map() function allowed local attackers to
     cause a system panic and a denial-of-service, related to RDS_GET_MR and
     RDS_GET_MR_FOR_DEST (bnc#1082962).
