  script_tag(name:"insight", value:"The openSUSE Leap 42.1 kernel was updated to receive various security and
  bugfixes.

  The following security bugs were fixed:

  - 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 cause a denial of
  service (invalid free) or possibly have unspecified other impact via an
  application that made an IPV6_RECVPKTINFO setsockopt system call
  (bnc#1026024).

  - 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
  (bnc#1025235).

  - 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 (bnc#1024938).

  - CVE-2017-5897: A potential remote denial of service within the IPv6 GRE
  protocol was fixed. (bsc#1023762)

  The following non-security bugs were fixed:

  - btrfs: support NFSv2 export (bnc#929871).

  - btrfs: Direct I/O: Fix space accounting (bsc#1025058).

  - btrfs: add RAID 5/6 BTRFS_RBIO_REBUILD_MISSING operation (bsc#1025069).

  - btrfs: bail out if block group has different mixed flag (bsc#1025072).

  - btrfs: be more precise on errors when getting an inode from disk
  (bsc#981038).

  - btrfs: check pending chunks when shrinking fs to avoid corruption
  (bnc#936445).

  - btrfs: check prepare_uptodate_page() error code earlier (bnc#966910).

  - btrfs: do not BUG() during drop snapshot (bsc#1025076).

  - btrfs: do not collect ordered extents when logging that inode exists
  (bsc#977685).

  - btrfs: do not initialize a space info as full to prevent ENOSPC
  (bnc#944001).

  - btrfs: do not leak reloc root nodes on error (bsc#1025074).

  - btrfs: fix block group -&amp gt space_info null pointer dereference
  (bnc#935088).

  - btrfs: fix chunk allocation regression leading to transaction abort
  (bnc#938550).

  - btrfs: fix crash on close_ctree() if cleaner starts new transaction
  (bnc#938891).

  - btrfs: fix deadlock between direct IO reads and buffered writes
  (bsc#973855).

  - btrfs: fix deadlock between direct IO write and defrag/readpages
  (bnc#965344).

  - btrfs: fix device replace of a missing RAID 5/6 device (bsc#1025057).

  - btrfs: fix empty symlink after creating symlink and fsync pa ...
