  script_tag(name:"insight", value:"The SUSE Linux Enterprise 11 SP3 LTSS kernel was updated receive various security and bugfixes.
The following security bugs were fixed:
- 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-2016-10200: 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-2017-2647: The KEYS subsystem in the Linux kernel allowed local
 users to gain privileges or cause a denial of service (NULL pointer
 dereference and system crash) via vectors involving a NULL value for a
 certain match field, related to the keyring_search_iterator function in
 keyring.c (bsc#1030593).
- CVE-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux
 kernel was too late in obtaining a certain lock and consequently could
 not ensure that disconnect function calls are safe, which allowed local
 users to cause a denial of service (panic) by leveraging access to the
 protocol value of IPPROTO_ICMP in a socket system call (bnc#1031003)
- CVE-2017-5669: The do_shmat function in ipc/shm.c in the Linux kernel
 did not restrict the address calculated by a certain rounding operation,
 which allowed local users to map page zero, and consequently bypass a
 protection mechanism that exists for the mmap system call, by making
 crafted shmget and shmat system calls in a privileged context
 (bnc#1026914)
- CVE-2017-5970: The ipv4_pktinfo_prepare function in
 net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a
 denial of service (system crash) via (1) an application that made
 crafted system calls or possibly (2) IPv4 traffic with invalid IP
 options (bsc#1024938)
- CVE-2017-5986: Race condition in the sctp_wait_for_sndbuf function in
 net/sctp/socket.c in the Linux kernel allowed local users to cause a
 denial of service (assertion failure and panic) via a multithreaded
 application that peels off an association in a certain buffer-full state
 (bsc#1025235)
- CVE-2017-6074: The dccp_rcv_state_process function in net/dccp/input.c
 in the Linux kernel mishandled DCCP_PKT_REQUEST packet data structures
 in the LISTEN state, which allowed local users to obtain root privileges
 or cause a denial of service (double free) via an application that made
 an IPV6_RECVPKTINFO setsockopt system call (bnc#1026024)
- CVE-2017-6214: The tcp_splice_read function in net/ipv4/tcp.c in the
 Linux kernel allowed remote attackers to cause a denial of service
 (infinite loop and soft lockup) via ... [Please see the references for more information on the vulnerabilities]");
