   SUSE Security Update: Security update for the Linux Kernel
______________________________________________________________________________

Announcement ID:    SUSE-SU-2017:1615-1
Rating:             critical
References:         #1039348 #1042292 
Cross-References:   CVE-2017-1000364
Affected Products:
                    SUSE OpenStack Cloud 6
                    SUSE Linux Enterprise Server for SAP 12-SP1
                    SUSE Linux Enterprise Server 12-SP1-LTSS

______________________________________________________________________________

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

Description:


   The SUSE Linux Enterprise 12 SP1 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:

   netfilter: A use-after-free was fixed that could cause a kernel panic on a
   system shutdown. (bsc#1042292)
