______________________________________________________________________________
An update that solves 17 vulnerabilities and has 25 fixes
is now available.
Description:
The SUSE Linux Enterprise 11 SP4 Realtime kernel was updated to receive
various security and bugfixes.
The following security bugs were fixed:
- CVE-2015-1339: Memory leak in the cuse_channel_release function in
fs/fuse/cuse.c in the Linux kernel allowed local users to cause a denial
of service (memory consumption) or possibly have unspecified other
impact by opening /dev/cuse many times (bnc#969356).
- CVE-2015-7566: The clie_5_attach function in drivers/usb/serial/visor.c
in the Linux kernel allowed physically proximate attackers to cause a
denial of service (NULL pointer dereference and system crash) or
possibly have unspecified other impact by inserting a USB device that
lacks a bulk-out endpoint (bnc#961512).
- CVE-2015-8551: The PCI backend driver in Xen, when running on an x86
system and using Linux 3.1.x through 4.3.x as the driver domain, allowed
local guest administrators to hit BUG conditions and cause a denial of
service (NULL pointer dereference and host OS crash) by leveraging a
system with access to a passed-through MSI or MSI-X capable physical PCI
device and a crafted sequence of XEN_PCI_OP_* operations, aka "Linux
pciback missing sanity checks (bnc#957990).
- CVE-2015-8552: The PCI backend driver in Xen, when running on an x86
system and using Linux 3.1.x through 4.3.x as the driver domain, allowed
local guest administrators to generate a continuous stream
of WARN messages and cause a denial of service (disk consumption) by
leveraging a system with access to a passed-through MSI or MSI-X
capable physical PCI device and XEN_PCI_OP_enable_msi operations, aka
"Linux pciback missing sanity checks (bnc#957990).
- CVE-2015-8816: The hub_activate function in drivers/usb/core/hub.c in
the Linux kernel did not properly maintain a hub-interface data
structure, which allowed physically proximate attackers to cause a
denial of service (invalid memory access and system crash) or possibly
have unspecified
other impact by unplugging a USB hub device (bnc#968010).
- CVE-2016-2143: The fork implementation in the Linux kernel on s390
platforms mishandles the case of four page-table levels, which allowed
local users to cause a denial of service (system crash) or possibly have
unspecified other impact via a crafted application, related to
arch/s390/include/asm/mmu_context.h and arch/s390/include/asm/pgalloc.h
(bnc#970504).

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-2016-2782: The treo_attach function in drivers/usb/serial/visor.c in
the Linux kernel allowed physically proximate attackers to cause a
denial of service (NULL pointer dereference and system crash) or
possibly have unspecified other impact by inserting a USB device that
lacks a (1) bulk-in or (2) interrupt-in endpoint (bnc#968670).
- 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 (bnc#970948).
- 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).
- CVE-2016-3139: The wacom_probe function in
drivers/input/tablet/wacom_sys.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#970909).
- 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-2016-3156: The IPv4 implementation in the Linux kernel mishandles
destruction of device objects, which allowed guest OS users to cause a
denial of service (host OS networking outage) by arranging for a large
number of IP addresses (bnc#971360).
