Beschreibung:	Summary: The remote host is missing an update for the 'kernel' package(s) announced via the openSUSE-SU-2018:3817-1 advisory. Vulnerability Insight: The openSUSE Leap 42.3 kernel was updated to 4.4.162 to receive various security and bugfixes. The following security bugs were fixed: - CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping pagetable locks. If a syscall such as ftruncate() removes entries from the pagetables of a task that is in the middle of mremap(), a stale TLB entry can remain for a short time that permits access to a physical page after it has been released back to the page allocator and reused. (bnc#1113769). - CVE-2018-18710: An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658 (bnc#1113751). - CVE-2018-18690: A local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandled ATTR_REPLACE operations with conversion of an attr from short to long form (bnc#1105025). - CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are able to access pseudo terminals) to hang/block further usage of any pseudo terminal devices due to an EXTPROC versus ICANON confusion in TIOCINQ (bnc#1094825). - CVE-2018-9516: A lack of certain checks in the hid_debug_events_read() function in the drivers/hid/hid-debug.c file might have resulted in receiving userspace buffer overflow and an out-of-bounds write or to the infinite loop. (bnc#1108498). The following non-security bugs were fixed: - 6lowpan: iphc: reset mac_header after decompress to fix panic (bnc#1012382). - Add azure kernel description. - Add bug reference to patches.suse/x86-entry-64-use-a-per-cpu-trampoline-stack-fix1.patch - Add graphviz to buildreq for image conversion - Add reference to bsc#1104124 to patches.fixes/fs-aio-fix-the-increment-of-aio-nr-and-counting-agai.patch - ALSA: hda: Add AZX_DCAPS_PM_RUNTIME for AMD Raven Ridge (bnc#1012382). - ALSA: hda/realtek - Cannot adjust speaker's volume on Dell XPS 27 7760 (bnc#1012382). - apparmor: remove no-op permission check in policy_unpack (git-fixes). - ARC: build: Get rid of toolchain check (bnc#1012382). - ARC: clone syscall to setp r25 as thread pointer (bnc#1012382). - arch/hexagon: fix kernel/dma.c build warning (bnc#1012382). - arch-symbols: use bash as interpreter since the script uses bashism. ...
