  script_tag(name:"insight", value:"The openSUSE Leap 42.3 kernel was updated to 4.4.114 to receive various
  security and bugfixes.

  The following security bugs were fixed:

  - CVE-2017-5715: Systems with microprocessors utilizing speculative
  execution and indirect branch prediction may allow unauthorized
  disclosure
  of information to an attacker with local user access via a side-channel
  analysis (bnc#1068032).

  The previous fix using CPU Microcode has been complemented by building
  the Linux Kernel with return trampolines aka 'retpolines'.

  - CVE-2018-5333: In the Linux kernel the rds_cmsg_atomic function in
  net/rds/rdma.c mishandled cases where page pinning fails or an invalid
  address is supplied, leading to an rds_atomic_free_op NULL pointer
  dereference (bnc#1075617).

  - CVE-2018-5332: In the Linux kernel the rds_message_alloc_sgs() function
  did not validate a value that is used during DMA page allocation,
  leading to a heap-based out-of-bounds write (related to the
  rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621).

  - CVE-2017-17862: kernel/bpf/verifier.c in the Linux kernel ignores
  unreachable code, even though it would still be processed by JIT
  compilers. This behavior, also considered an improper branch-pruning
  logic issue, could possibly be used by local users for denial of service
  (bnc#1073928).

  - CVE-2017-17864: kernel/bpf/verifier.c in the Linux kernel mishandled
  states_equal comparisons between the pointer data type and the
  UNKNOWN_VALUE data type, which allowed local users to obtain potentially
  sensitive address information, aka a 'pointer leak (bnc#1073928).

  - CVE-2017-17712: The raw_sendmsg() function in net/ipv4/raw.c in the
  Linux kernel had a race condition in inet- hdrincl that lead to
  uninitialized stack pointer usage  this allowed a local user to execute
  code and gain privileges (bnc#1073229 1073230).

  - CVE-2017-15129: A use-after-free vulnerability was found in network
  namespaces code affecting the Linux kernel The function
  get_net_ns_by_id() in net/core/net_namespace.c did not check for the
  net::count value after it has found a peer network in netns_ids idr,
  which could lead to double free and memory corruption. This
  vulnerability could allow an unprivileged local user to induce kernel
  memory corruption on the system, leading to a crash. Due to the nature
  of the flaw, privilege escalation cannot be fully ruled out, although it
  is thought to be unlikely (bnc#1074839).

  - CVE-2017-18017: The tcpmss_mangle_packet function in
  net/netfilter/xt_TCPMSS.c in the Linux kernel allowed remote attackers
  to cause a denial of s ...
