An update that solves 11 vulnerabilities and has 7 fixes is
now available.

Description:



The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive
various security and bugfixes.

The following security bugs were fixed:

- CVE-2018-1087: And an unprivileged KVM guest user could use this flaw to
potentially escalate their privileges inside a guest. (bsc#1087088)
- CVE-2018-8897: An unprivileged system user could use incorrect set up
interrupt stacks to crash the Linux kernel resulting in DoS issue.
(bsc#1087088)
- CVE-2018-8781: The udl_fb_mmap function in drivers/gpu/drm/udl/udl_fb.c
had an integer-overflow vulnerability allowing local users with access
to the udldrmfb driver to obtain full read and write permissions on
kernel physical pages, resulting in a code execution in kernel space
(bnc#1090643).
- CVE-2018-10124: The kill_something_info function in kernel/signal.c
might allow 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 in might
allow 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-2017-13220: An elevation of privilege vulnerability in the Upstream
kernel bluez was fixed. (bnc#1076537).
- CVE-2017-11089: A buffer overread is observed in nl80211_set_station
when user space application sends attribute
NL80211_ATTR_LOCAL_MESH_POWER_MODE with data of size less than 4 bytes
(bnc#1088261).
- 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).
- CVE-2018-8822: Incorrect buffer length handling in the ncp_read_kernel
function in fs/ncpfs/ncplib_kernel.c could be exploited by malicious
NCPFS servers to crash the kernel or execute code (bnc#1086162).
- CVE-2017-18203: The dm_get_from_kobject function in drivers/md/dm.c
allowed 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).

The following non-security bugs were fixed:

- Integrate fixes resulting from bsc#1088147 More info in the respective
commit messages.
- kabi: x86/kaiser: properly align trampoline stack (bsc#1087260).
- dcache: Add cond_resched in shrink_dentry_list (bsc#1086194).
- kGraft: fix small race in reversion code (bsc#1083125).
- kabi/severities: Ignore kgr_shadow_* kABI changes
- kvm/x86: fix icebp instruction handling (bsc#1087088).
- livepatch: Allow to call a custom callback when freeing shadow variables
(bsc#1082299 fate#313296).
- livepatch: Initialize shadow variables safely by a custom callback
(bsc#1082299 fate#313296).
- usbnet: Fix a race between usbnet_stop() and the BH (bsc#1083275).
- x86/entry/64: Do not use IST entry for #BP stack (bsc#1087088).
- x86/espfix: Fix return stack in do_double_fault() (bsc#1085279).
- x86/kaiser: properly align trampoline stack (bsc#1087260).
- x86/retpoline: do not perform thunk calls in ring3 vsyscall code
(bsc#1085331).
