This update for openssh fixes the following issues :
Prevent user enumeration through the timing of password processing (bsc#989363, CVE-2016-6210) [-prevent_timing_user_enumeration]
Allow lowering the DH groups parameter limit in server as well as when GSSAPI key exchange is used (bsc#948902)
limit accepted password length (prevents possible DoS) (bsc#992533, CVE-2016-6515) Bug fixes :
avoid complaining about unset DISPLAY variable (bsc#981654)
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
