   An update that fixes three vulnerabilities is now
   available. It includes one version update.

Description:


   The SUSE Linux Enterprise 11 Service Pack 3 RealTime Extension kernel has
   been updated to fix two critical security issues.

   The following security bugs have been fixed:

       *

         CVE-2014-1737: The raw_cmd_copyin function in drivers/block/floppy.c
   in the Linux kernel through 3.14.3 does not properly handle error
   conditions during processing of an FDRAWCMD ioctl call, which allows local
   users to trigger kfree operations and gain privileges by leveraging write
   access to a /dev/fd device. (bnc#875798)

       *

         CVE-2014-1738: The raw_cmd_copyout function in
   drivers/block/floppy.c in the Linux kernel through 3.14.3 does not
   properly restrict access to certain pointers during processing of an
   FDRAWCMD ioctl call, which allows local users to obtain sensitive
   information from kernel heap memory by leveraging write access to a
   /dev/fd device. (bnc#875798)

       *

         CVE-2014-0196: The n_tty_write function in drivers/tty/n_tty.c in
   the Linux kernel through 3.14.3 does not properly manage tty driver access
   in the "LECHO & !OPOST" case, which allows local users to cause a denial
   of service (memory corruption and system crash) or gain privileges by
   triggering a race condition involving read and write operations with long
   strings. (bnc#875690)

   Security Issue references:

       * CVE-2014-0196
         
       * CVE-2014-1737
