various security and bugfixes. The following security bugs were
fixed :
- CVE-2018-3620: Local attackers on baremetal systems
could use speculative code patterns on hyperthreaded
processors to read data present in the L1 Datacache used
by other hyperthreads on the same CPU core, potentially
leaking sensitive data. (bnc#1087081).
- CVE-2018-3646: Local attackers in virtualized guest
systems could use speculative code patterns on
hyperthreaded processors to read data present in the L1
Datacache used by other hyperthreads on the same CPU
core, potentially leaking sensitive data, even from
other virtual machines or the host system.
(bnc#1089343).
- CVE-2018-5390 aka 'SegmentSmack': The Linux Kernel can
be forced to make very expensive calls to
tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for
every incoming packet which can lead to a denial of
service (bnc#1102340).
- CVE-2018-5391 aka 'FragmentSmack': A flaw in the IP
packet reassembly could be used by remote attackers to
consume lots of CPU time (bnc#1103097).
- CVE-2018-14734: drivers/infiniband/core/ucma.c allowed
ucma_leave_multicast to access a certain data structure
after a cleanup step in ucma_process_join, which allowed
attackers to cause a denial of service (use-after-free)
(bnc#1103119).
- CVE-2017-18344: The timer_create syscall implementation
in kernel/time/posix-timers.c didn't properly validate
the sigevent->sigev_notify field, which leads to
out-of-bounds access in the show_timer function (called
when /proc/$PID/timers is read). This allowed userspace
applications to read arbitrary kernel memory (on a
kernel built with CONFIG_POSIX_TIMERS and
CONFIG_CHECKPOINT_RESTORE) (bnc#1102851 bnc#1103580).
- CVE-2018-9385: When printing the 'driver_override'
option from with-in the amba driver, a very long line
could expose one additional uninitialized byte
(bnc#1100491).
- CVE-2018-13053: The alarm_timer_nsleep function in
kernel/time/alarmtimer.c had an integer overflow via a
large relative timeout because ktime_add_safe is not
used (bnc#1099924).
- CVE-2018-13405: The inode_init_owner function in
fs/inode.c allowed local users to create files with an
unintended group ownership, in a scenario where a
directory is SGID to a certain group and is writable by
a user who is not a member of that group. Here, the
non-member can trigger creation of a plain file whose
group ownership is that group. The intended behavior was
that the non-member can trigger creation of a directory
(but not a plain file) whose group ownership is that
group. The non-member can escalate privileges by making
the plain file executable and SGID (bnc#1100416).
- CVE-2018-13406: An integer overflow in the
uvesafb_setcmap function in
drivers/video/fbdev/uvesafb.c could result in local
attackers being able to crash the kernel or potentially
elevate privileges because kmalloc_array is not used
(bnc#1098016 1100418).
- CVE-2018-5814: Multiple race condition errors when
handling probe, disconnect, and rebind operations could
be exploited to trigger a use-after-free condition or a
NULL pointer dereference by sending multiple USB over IP
packets (bnc#1096480).
The update package also includes non-security fixes. See advisory for
details.
Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
