  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 GA LTSS kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2015-1350: The VFS subsystem in the Linux kernel provided an
 incomplete set of requirements for setattr operations that
 underspecifies removing extended privilege attributes, which allowed
 local users to cause a denial of service (capability stripping) via a
 failed invocation of a system call, as demonstrated by using chown to
 remove a capability from the ping or Wireshark dumpcap program
 (bnc#914939).
- CVE-2016-2117: The atl2_probe function in
 drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly
 enabled scatter/gather I/O, which allowed remote attackers to obtain
 sensitive information from kernel memory by reading packet data
 (bnc#968697).
- CVE-2016-3070: The trace_writeback_dirty_page implementation in
 include/trace/events/writeback.h in the Linux kernel improperly
 interacted with mm/migrate.c, which allowed local users to cause a
 denial of service (NULL pointer dereference and system crash) or
 possibly have unspecified other impact by triggering a certain page move
 (bnc#979215).
- CVE-2016-5243: The tipc_nl_compat_link_dump function in
 net/tipc/netlink_compat.c in the Linux kernel did not properly copy a
 certain string, which allowed local users to obtain sensitive
 information from kernel stack memory by reading a Netlink message
 (bnc#983212).
- CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg
 function in net/socket.c in the Linux kernel allowed remote attackers to
 execute arbitrary code via vectors involving a recvmmsg system call that
 is mishandled during error processing (bnc#1003077).
- CVE-2016-9588: arch/x86/kvm/vmx.c in the Linux kernel mismanages the #BP
 and #OF exceptions, which allowed guest OS users to cause a denial of
 service (guest OS crash) by declining to handle an exception thrown by
 an L2 guest (bnc#1015703).
- CVE-2016-10044: The aio_mount function in fs/aio.c in the Linux kernel
 did not properly restrict execute access, which made it easier for local
 users to bypass intended SELinux W^X policy restrictions, and
 consequently gain privileges, via an io_setup system call (bnc#1023992).
- CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in
 the Linux kernel allowed local users to gain privileges or cause a
 denial of service (use-after-free) by making multiple bind system calls
 without properly ascertaining whether a socket has the SOCK_ZAPPED
 status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c
 (bnc#1028415).
- CVE-2016-10208: The ext4_fill_super function in fs/ext4/super.c in the
 Linux kernel did not properly validate meta block groups, which allowed
 physically proximate attackers to cause a denial of service
 (out-of-bounds read and system crash) via a crafted ext4 image
 (bnc#1023377).
- CVE-2017-2671: The ... [Please see the references for more information on the vulnerabilities]");
