An update that fixes two vulnerabilities is now available.

Description:


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).


Patch Instructions:

To install this SUSE Security Update use YaST online_update.
Alternatively you can run the command listed for your product:

- SUSE Linux Enterprise Server 11-SP3-LTSS:

zypper in -t patch slessp3-kernel-13156=1
