   An update that solves four vulnerabilities and has three
   fixes is now available.


   This update for openssh-openssl1 fixes the following issues:

   These security issues were fixed:

   - CVE-2016-10708: Prevent NULL pointer dereference via an out-of-sequence
     NEWKEYS message allowed remote attackers to cause a denial of service
   - CVE-2017-15906: The process_open function did not properly prevent write
     operations in readonly mode, which allowed attackers to create
      zero-length files (bsc#1065000).
   - CVE-2016-10012: The shared memory manager (associated with
     pre-authentication compression) did not ensure that a bounds check is
     enforced by all compilers, which might have allowed local users to gain
     privileges by leveraging access to a sandboxed privilege-separation
     process, related to the m_zback and m_zlib data structures (bsc#1016370).
   - CVE-2008-1483: Prevent local users from hijacking forwarded X
     connections by causing ssh to set DISPLAY to :10, even when another
     process is listening on the associated port. This problem was
     reontroduced by another patch and was previously fixed by another update

   These non-security issues were fixed:

   - Remove duplicate KEX method (bsc#1053972)
   - New switch for printing diagnostic messages in sftp client's batch mode
   - Enable case-insensitive hostname matching (bsc#1017099)
