SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2016:1696-1)

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


Synopsis :

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

Description :

The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.59 to
receive various security and bugfixes.

Main feature additions :

- Improved support for Clustered File System (CephFS,
fate#318586).

- Addition of kGraft patches now produces logging messages
to simplify auditing (fate#317827).

The following security bugs were fixed :

- CVE-2016-1583: Prevent the usage of mmap when the lower
file system does not allow it. This could have lead to
local privilege escalation when ecryptfs-utils was
installed and /sbin/mount.ecryptfs_private was setuid
(bsc#983143).

- CVE-2014-9717: fs/namespace.c in the Linux kernel
processes MNT_DETACH umount2 system calls without
verifying that the MNT_LOCKED flag is unset, which
allowed local users to bypass intended access
restrictions and navigate to filesystem locations
beneath a mount by calling umount2 within a user
namespace (bnc#928547).

- CVE-2016-2185: The ati_remote2_probe function in
drivers/input/misc/ati_remote2.c in the Linux kernel
allowed physically proximate attackers to cause a denial
of service (NULL pointer dereference and system crash)
via a crafted endpoints value in a USB device descriptor
(bnc#971124).

- CVE-2016-2186: The powermate_probe function in
drivers/input/misc/powermate.c in the Linux kernel
allowed physically proximate attackers to cause a denial
of service (NULL pointer dereference and system crash)
via a crafted endpoints value in a USB device descriptor
(bnc#970958).

drivers/usb/misc/iowarrior.c in the Linux kernel allowed
physically proximate attackers to cause a denial of
service (NULL pointer dereference and system crash) via
a crafted endpoints value in a USB device descriptor
(bnc#970956).

- CVE-2016-2847: fs/pipe.c in the Linux kernel did not
limit the amount of unread data in pipes, which allowed
local users to cause a denial of service (memory
consumption) by creating many pipes with non-default
sizes (bsc#970948).

- CVE-2016-3134: The netfilter subsystem in the Linux
kernel did not validate certain offset fields, which
allowed local users to gain privileges or cause a denial
of service (heap memory corruption) via an
IPT_SO_SET_REPLACE setsockopt call (bnc#971126 971793).

- CVE-2016-3136: The mct_u232_msr_to_state function in
drivers/usb/serial/mct_u232.c in the Linux kernel
allowed physically proximate attackers to cause a denial
of service (NULL pointer dereference and system crash)
via a crafted USB device without two interrupt-in
endpoint descriptors (bnc#970955).

- CVE-2016-3137: drivers/usb/serial/cypress_m8.c in the
Linux kernel allowed physically proximate attackers to
cause a denial of service (NULL pointer dereference and
system crash) via a USB device without both an
interrupt-in and an interrupt-out endpoint descriptor,
related to the cypress_generic_port_probe and
cypress_open functions (bnc#970970).

- CVE-2016-3138: The acm_probe function in
drivers/usb/class/cdc-acm.c in the Linux kernel allowed
physically proximate attackers to cause a denial of
service (NULL pointer dereference and system crash) via
a USB device without both a control and a data endpoint
descriptor (bnc#970911 970970).

- CVE-2016-3140: The digi_port_init function in
drivers/usb/serial/digi_acceleport.c in the Linux kernel
allowed physically proximate attackers to cause a denial
of service (NULL pointer dereference and system crash)
via a crafted endpoints value in a USB device descriptor
(bnc#970892).

- CVE-2016-3689: The ims_pcu_parse_cdc_data function in
drivers/input/misc/ims-pcu.c in the Linux kernel allowed
physically proximate attackers to cause a denial of
service (system crash) via a USB device without both a
master and a slave interface (bnc#971628).

- CVE-2016-3951: Double free vulnerability in
drivers/net/usb/cdc_ncm.c in the Linux kernel allowed
physically proximate attackers to cause a denial of
service (system crash) or possibly have unspecified
other impact by inserting a USB device with an invalid
USB descriptor (bnc#974418).
