______________________________________________________________________________
An update that solves 18 vulnerabilities and has 36 fixes
is now available.
Description:
The SUSE Linux Enterprise 11 SP4 RT kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
- CVE-2018-10124: The kill_something_info function in kernel/signal.c
might have allowed local users to cause a denial of service via an
INT_MIN argument (bnc#1089752).
- CVE-2018-10087: The kernel_wait4 function in kernel/exit.c might have
allowed local users to cause a denial of service by triggering an
attempted use of the
-INT_MIN value (bnc#1089608).
- CVE-2018-7757: Memory leak in the sas_smp_get_phy_events function in
drivers/scsi/libsas/sas_expander.c allowed local users to cause a denial
of service (memory consumption) via many read accesses to files in the
/sys/class/sas_phy directory, as demonstrated by the
/sys/class/sas_phy/phy-1:0:12/invalid_dword_count file (bnc#1084536).
- CVE-2018-7566: Buffer overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL
ioctl write operation to /dev/snd/seq by a local user potentially
allowing for code execution (bnc#1083483).
- CVE-2017-0861: Use-after-free vulnerability in the snd_pcm_info function
in the ALSA subsystem allowed attackers to gain privileges via
unspecified vectors (bnc#1088260 1088268).
- CVE-2018-8822: Incorrect buffer length handling in the ncp_read_kernel
function could have beenexploited by malicious NCPFS servers to crash
the kernel or execute code (bnc#1086162).
- CVE-2017-13166: Prevent elevation of privilege vulnerability in the
video driver (bnc#1072865).
- CVE-2017-18203: The dm_get_from_kobject function in drivers/md/dm.c
allow local users to cause a denial of service (BUG) by leveraging a
race condition with __dm_destroy during creation and removal of DM
devices (bnc#1083242).
- CVE-2017-16911: The vhci_hcd driver allowed local attackers to disclose
kernel memory addresses. Successful exploitation requires that a USB
device is attached over IP (bnc#1078674).
- CVE-2017-18208: The madvise_willneed function in mm/madvise.c allowed
local users to cause a denial of service (infinite loop) by triggering
use of MADVISE_WILLNEED for a DAX mapping (bnc#1083494).
- CVE-2017-16644: The hdpvr_probe function in
drivers/media/usb/hdpvr/hdpvr-core.c allowed local users to cause a
denial of service (improper error handling and system crash) or possibly
have unspecified
other impact via a crafted USB device (bnc#1067118).
- CVE-2018-6927: The futex_requeue function in kernel/futex.c allowed
attackers to cause a denial of service (integer overflow) or possibly
have unspecified
other impact by triggering a negative wake or requeue value
(bnc#1080757).
- CVE-2017-16914: The "stub_send_ret_submit()" function
(drivers/usb/usbip/stub_tx.c) allowed attackers to cause a denial of
service (NULL pointer dereference) via a specially crafted USB over IP
packet (bnc#1078669).
- CVE-2016-7915: The hid_input_field function in drivers/hid/hid-core.c
allowed physically proximate attackers to obtain sensitive information
from kernel memory or cause a denial of service (out-of-bounds read) by
connecting a device, as demonstrated by a Logitech DJ receiver
(bnc#1010470).
- CVE-2015-5156: The virtnet_probe function in drivers/net/virtio_net.c
attempted to support a FRAGLIST feature without proper memory
allocation, which allowed guest OS users to cause a denial of service
(buffer overflow and memory corruption) via a crafted sequence of
fragmented packets (bnc#940776).
- CVE-2017-12190: The bio_map_user_iov and bio_unmap_user functions in
block/bio.c did unbalanced refcounting when a SCSI I/O vector had small
consecutive buffers belonging to the same page. The bio_add_pc_page
function merged them into one, but the page reference was never dropped.
This caused a memory leak and possible system lockup (exploitable
against the host OS by a guest OS user, if a SCSI disk is passed through
to a virtual machine) due to an
out-of-memory condition (bnc#1062568).
- CVE-2017-16912: The "get_pipe()" function (drivers/usb/usbip/stub_rx.c)
allowed attackers to cause a denial of service (out-of-bounds read) via
a specially crafted USB over IP packet (bnc#1078673).
- CVE-2017-16913: The "stub_recv_cmd_submit()" function
(drivers/usb/usbip/stub_rx.c) when handling CMD_SUBMIT packets allowed
attackers to cause a denial of service (arbitrary memory allocation) via
a specially crafted USB over IP packet (bnc#1078672).
