  script_tag(name:"insight", value:"The openSUSE Leap 42.2 kernel was updated to 4.4.56 fix various security
  issues and bugs.

  The following security bugs were fixed:

  - CVE-2017-7184: The xfrm_replay_verify_len function in
  net/xfrm/xfrm_user.c in the Linux kernel did not validate certain size
  data after an XFRM_MSG_NEWAE update, which allowed local users to obtain
  root privileges or cause a denial of service (heap-based out-of-bounds
  access) by leveraging the CAP_NET_ADMIN capability, as demonstrated
  during a Pwn2Own competition at CanSecWest 2017 for the Ubuntu 16.10
  linux-image-* package 4.8.0.41.52 (bnc#1030573).

  - 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-2017-2636: Race condition in drivers/tty/n_hdlc.c in the Linux
  kernel allowed local users to gain privileges or cause a denial of
  service (double free) by setting the HDLC line discipline (bnc#1027565).

  - CVE-2017-6345: The LLC subsystem in the Linux kernel did not ensure that
  a certain destructor exists in required circumstances, which allowed
  local users to cause a denial of service (BUG_ON) or possibly have
  unspecified other impact via crafted system calls (bnc#1027190).

  - CVE-2017-6346: Race condition in net/packet/af_packet.c in the Linux
  kernel allowed local users to cause a denial of service (use-after-free)
  or possibly have unspecified other impact via a multithreaded
  application that made PACKET_FANOUT setsockopt system calls
  (bnc#1027189).

  - CVE-2017-6353: net/sctp/socket.c in the Linux kernel did not properly
  restrict association peel-off operations during certain wait states,
  which allowed local users to cause a denial of service (invalid unlock
  and double free) via a multithreaded application.  NOTE: this
  vulnerability exists because of an incorrect fix for CVE-2017-5986
  (bnc#1025235).

  - 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 vectors involving a TCP packet with
  the URG flag (bnc#1026722).

  - CVE-2016-2117: The atl2_probe function in
  drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly
  enables scatter/gather I/O, which allowed remote attackers to obtain
  sensitive information from kernel memory by reading packet ...
