  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2018-1068: Fixed flaw in the implementation of 32-bit syscall
 interface for bridging. This allowed a privileged user to arbitrarily
 write to a limited range of kernel memory (bnc#1085107).
- CVE-2017-18221: The __munlock_pagevec function allowed local users to
 cause a denial of service (NR_MLOCK accounting corruption) via crafted
 use of mlockall and munlockall system calls (bnc#1084323).
- CVE-2018-1066: Prevent NULL pointer dereference in
 fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allowed an attacker
 controlling a CIFS server to kernel panic a client that has this server
 mounted, because an empty TargetInfo field in an NTLMSSP setup
 negotiation response was mishandled during session recovery
 (bnc#1083640).
- CVE-2017-13166: Prevent elevation of privilege vulnerability in the
 kernel v4l2 video driver (bnc#1072865).
- CVE-2017-16911: The vhci_hcd driver allowed local attackers to disclose
 kernel memory addresses. Successful exploitation required that a USB
 device was attached over IP (bnc#1078674).
- CVE-2017-15299: The KEYS subsystem mishandled use of add_key for a key
 that already exists but is uninstantiated, which allowed local users to
 cause a denial of service (NULL pointer dereference and system crash) or
 possibly have unspecified other impact via a crafted system call
 (bnc#1063416).
- CVE-2017-18208: The madvise_willneed function kernel allowed local users
 to cause a denial of service (infinite loop) by triggering use of
 MADVISE_WILLNEED for a DAX mapping (bnc#1083494).
- CVE-2018-7566: The ALSA sequencer core initializes the event pool on
 demand by invoking snd_seq_pool_init() when the first write happens and
 the pool is empty. A user could have reset the pool size manually via
 ioctl concurrently, which may have lead UAF or out-of-bound access
 (bsc#1083483).
- CVE-2017-18204: The ocfs2_setattr function allowed local users to cause
 a denial of service (deadlock) via DIO requests (bnc#1083244).
- CVE-2017-16644: The hdpvr_probe function allowed local users to cause a
 denial of service (improper error handling and system crash) or possibly
 have unspecified other impact via a crafted USB device (bnc#1067118).
- CVE-2018-6927: The futex_requeue function allowed attackers to cause a
 denial
 of service (integer overflow) or possibly have unspecified other impact
 by triggering a negative wake or requeue value (bnc#1080757).
- CVE-2017-16914: The 'stub_send_ret_submit()' function allowed attackers
 to cause a denial of service (NULL pointer dereference) via a specially
 crafted USB over IP packet (bnc#1078669).
- CVE-2016-7915: The hid_input_field function allowed physically proximate
 attackers to obtain sensitive information from kernel memory or cause a
 denial
 of service (out-of-bounds read) by ... [Please see the references for more information on the vulnerabilities]");
