SUSE SLES11 Security Update : kernel (SUSE-SU-2017:1613-1) (Stack Clash)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

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).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
