SUSE SLES11 Security Update : kernel (SUSE-SU-2014:1698-1)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

The SUSE Linux Enterprise 11 Service Pack 2 LTSS kernel has been
updated to fix security issues on kernels on the x86_64 architecture.

The following security bugs have been fixed :

CVE-2014-9322: A local privilege escalation in the x86_64 32bit
compatibility signal handling was fixed, which could have been used by
local attackers to crash the machine or execute code.

CVE-2014-9090: The do_double_fault function in
arch/x86/kernel/traps.c in the Linux kernel did not properly
handle faults associated with the Stack Segment (SS) segment
register, which allowed local users to cause a denial of
service (panic) via a modify_ldt system call, as
demonstrated by sigreturn_32 in the 1-clock-tests test
suite.

CVE-2014-8133: Insufficient validation of TLS register usage
could have leaked information from the kernel stack to
userspace.

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.
