Announcement ID: SUSE-SU-2017:1618-1

Rating: critical

References: #1039348 #1042292

Cross-References: CVE-2017-1000364

Affected Products:

SUSE Linux Enterprise Server for SAP 12

SUSE Linux Enterprise Server 12-LTSS

SUSE Linux Enterprise Module for Public Cloud 12

______________________________________________________________________________

 

An update that solves one vulnerability and has one errata

is now available.

 

Description:

 

 

The SUSE Linux Enterprise 12 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)
