Security update for the Linux Kernel (critical)

The SUSE Linux Enterprise 11 SP3 kernel was updated to receive various
security fixes.

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)

• CVE-2015-3288: mm/memory.c in the Linux kernel mishandled anonymous
  pages, which allowed local users to gain privileges or cause a denial of
  service (page tainting) via a crafted application that triggers writing
  to page zero (bnc#979021).
