   An update that solves two vulnerabilities and has three
   fixes is now available.

Description:

   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 existance 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)
   - added pam_keyinit to pam configuration file (bsc#1081947)


   This update was imported from the SUSE:SLE-15:Update update project.
