   An update that solves three vulnerabilities and has 7 fixes
   is now available.

Description:

   openssh was updated to fix three security issues.

   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)
