- CVEs with nessus.description==The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.143 to
receive various security and bugfixes. The following security bugs
were fixed :
- CVE-2018-5390 aka 'SegmentSmack': Linux kernel could 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-2018-14734: drivers/infiniband/core/ucma.c in the
Linux kernel 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 lead 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-2018-3620: 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).
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.
