SUSE Security Update: Security update for the Linux Kernel

______________________________________________________________________________

 

Announcement ID: SUSE-SU-2017:1613-1

Rating: critical

References: #1039348 #979021

Cross-References: CVE-2015-3288 CVE-2017-1000364

Affected Products:

SUSE Linux Enterprise Server 11-SP3-LTSS

SUSE Linux Enterprise Server 11-EXTRA

SUSE Linux Enterprise Point of Sale 11-SP3

SUSE Linux Enterprise Debuginfo 11-SP3

______________________________________________________________________________

 

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).
