SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2015:0529-1)

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 12 kernel was updated to 3.12.38 to receive
various security and bugfixes.

This update contains the following feature enablements :

- The remote block device (rbd) and ceph drivers have been
enabled and are now supported. (FATE#318350) These can
be used e.g. for accessing the SUSE Enterprise Storage
product services.

- Support for Intel Select Bay trail CPUs has been added.

Following security issues were fixed :

- CVE-2014-9419: The __switch_to function in
arch/x86/kernel/process_64.c in the Linux kernel through
3.18.1 did not ensure that Thread Local Storage (TLS)
descriptors were loaded before proceeding with other
steps, which made it easier for local users to bypass
the ASLR protection mechanism via a crafted application
that reads a TLS base address (bnc#911326).

- CVE-2014-7822: A flaw was found in the way the Linux
kernels splice() system call validated its parameters.
On certain file systems, a local, unprivileged user
could have used this flaw to write past the maximum file
size, and thus crash the system.

- CVE-2014-8160: The connection tracking module could be
bypassed if a specific protocol module was not loaded,
e.g. allowing SCTP traffic while the firewall should
have filtered it.

- CVE-2014-9584: The parse_rock_ridge_inode_internal
function in fs/isofs/rock.c in the Linux kernel before
3.18.2 did not validate a length value in the Extensions
Reference (ER) System Use Field, which allowed local
users to obtain sensitive information from kernel memory
via a crafted iso9660 image (bnc#912654).
