This update for openssh fixes the following issues:

Issues addressed:

- Removed the "KexDHMin" config keyword (bsc#1127180)
It used to allow lowering of the minimal allowed DH group size,
which was increased to 2048 by upstream in the light of the Logjam
attack. However, the code was broken since the upgrade to 7.6p1.
It's still possible to use the fixed 1024-bit diffie-hellman-group1-sha1
key exchange method when working with legacy systems.
- Fixed two race conditions in sshd relating to SIGHUP (bsc#1119183)
