   An update that solves one vulnerability and has one errata
   is now available.

Description:


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


   The following security bugs were fixed:

   - CVE-2017-1000364: The default stack guard page was too small and could
     be "jumped over" by userland programs using more than one page of stack
     in functions and so lead to memory corruption. This update extends the
     stack guard page to 1 MB (for 4k pages) and 16 MB (for 64k pages) to
     reduce this attack vector. This is not a kernel bugfix, but a hardening
     measure against this kind of userland attack.(bsc#1039348)

   The following non-security bugs were fixed:

   - There was a load failure in the sha-mb encryption implementation
     (bsc#1037384).
