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) Patch Instructions: To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
