openSUSE: 2019:2017-1 Moderate: PuTTY SSH Protocol Security Fix

This update for putty fixes the following issues:

Update to new upstream release 0.72 [boo#1144547, boo#1144548]

* Fixed two separate vulnerabilities affecting the obsolete SSH-1

protocol, both available before host key checking.

* Fixed a vulnerability in all the SSH client tools (PuTTY, Plink, PSFTP

and PSCP) if a malicious program can impersonate Pageant.

* Fixed a crash in GSSAPI / Kerberos key exchange triggered if the server

provided an ordinary SSH host key as part of the exchange.
