Vulnerability Insight:
This update for openssh fixes the following issues:

- CVE-2018-15919: Remotely observable behaviour in auth-gss2.c in OpenSSH
could be used by remote attackers to detect existence of users on a
target system when GSS2 is in use. OpenSSH developers do not want to
treat such a username enumeration (or 'oracle') as a vulnerability.
(bsc#1106163)

- CVE-2018-15473: OpenSSH was prone to a user existence oracle
vulnerability due to not delaying bailout for an invalid authenticating
user until after the packet containing the request has been fully
parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c.
(bsc#1105010)

The following non-security issues were fixed:

- Stop leaking File descriptors (bsc#964336)

- sftp-client.c returns wrong error code upon failure (bsc#1091396)
