An update that solves 16 vulnerabilities and has 66 fixes
is now available.

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).
– CVE-2016-2188: The iowarrior_probe function in
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).
