An update that solves three vulnerabilities and has seven security fixes can now be installed.

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)
