  script_tag(name:"insight", value:"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)");
