______________________________________________________________________________

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

Description:

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
(bsc#1076957).
- 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
(bsc#1069509).

These non-security issues were fixed:

- Remove duplicate KEX method (bsc#1053972)
- New switch for printing diagnostic messages in sftp client's batch
mode
(bsc#1023275)
- Enable case-insensitive hostname matching (bsc#1017099)
