openSUSE Leap 42.3
______________________________________________________________________________

An update that solves 14 vulnerabilities and has 41 fixes
is now available.

Description:

The openSUSE Leap 42.3 kernel was updated to 4.4.143 to receive various
security and bugfixes.

The following security bugs were fixed:

– 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-2018-10876: A flaw was found in Linux kernel in the ext4 filesystem
code. A use-after-free is possible in ext4_ext_remove_space() function
when mounting and operating a crafted ext4 image. (bnc#1099811)
– CVE-2018-10877: Linux kernel ext4 filesystem is vulnerable to an
out-of-bound access in the ext4_ext_drop_refs() function when operating
on a crafted ext4 filesystem image. (bnc#1099846)
– CVE-2018-10878: A flaw was found in the ext4 filesystem. A local user
can cause an out-of-bounds write and a denial of service or unspecified
other impact is possible by mounting and operating a crafted ext4
filesystem image. (bnc#1099813)
– CVE-2018-10879: A flaw was found in the ext4 filesystem. A local user
can cause a use-after-free in ext4_xattr_set_entry function and a denial
of service or unspecified other impact may occur by renaming a file in a
crafted ext4 filesystem image. (bnc#1099844)
– CVE-2018-10880: Linux kernel is vulnerable to a stack-out-of-bounds
write in the ext4 filesystem code when mounting and writing to a crafted
ext4 image in ext4_update_inline_data(). An attacker could use this to
cause a system crash and a denial of service. (bnc#1099845)
– CVE-2018-10881: A flaw was found in the ext4 filesystem. A local user
can cause an out-of-bound access in ext4_get_group_info function, a
denial of service, and a system crash by mounting and operating on a
crafted ext4 filesystem image. (bnc#1099864)
– CVE-2018-10882: A flaw was found in the ext4 filesystem. A local user
can cause an out-of-bound write in in fs/jbd2/transaction.c code, a
denial of service, and a system crash by unmounting a crafted ext4
filesystem image. (bnc#1099849)
– CVE-2018-10883: A flaw was found in the ext4 filesystem. A local user
can cause an out-of-bounds write in jbd2_journal_dirty_metadata(), a
denial of service, and a system crash by mounting and operating on a
crafted ext4 filesystem image. (bnc#1099863)
– 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-2018-3620: Systems with microprocessors utilizing speculative
execution and address translations may allow unauthorized disclosure of
information residing in the L1 data cache to an attacker with local user
access via a terminal page fault and a side-channel analysis
(bnc#1087081 1089343 ).
– CVE-2018-3646: Systems with microprocessors utilizing speculative
execution and address translations may allow unauthorized disclosure of
information residing in the L1 data cache to an attacker with local user
access with guest OS privilege via a terminal page fault and a
side-channel analysis (bnc#1089343 1104365).
– CVE-2018-5390 aka “SegmentSmack”: The 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-2018-5391 aka “FragmentSmack”: A flaw in the IP packet reassembly
could be used by remote attackers to consume lots of CPU time
(bnc#1103097).
