These security issues were fixed:
- CVE-2016-3115: Multiple CRLF injection vulnerabilities in session.c in sshd in OpenSSH allowed remote authenticated users to bypass intended shell-command restrictions via crafted X11 forwarding data, related to the (1) do_authenticated1 and (2) session_x11_req functions (bsc#970632).
- CVE-2016-1908: Possible fallback from untrusted to trusted X11 forwarding (bsc#962313).
- CVE-2015-8325: Ignore PAM environment vars when UseLogin=yes (bsc#975865).

These non-security issues were fixed:
- Correctly parse GSSAPI KEX algorithms (bsc#961368)
- More verbose FIPS mode/CC related documentation in README.FIPS (bsc#965576, bsc#960414)
- Fix PRNG re-seeding (bsc#960414, bsc#729190)
- Disable DH parameters under 2048 bits by default and allow lowering the limit back to the RFC 4419 specified minimum through an option (bsc#932483, bsc#948902)
- Allow empty Match blocks (bsc#961494)");
