    Summary: Security update for openssh-openssl1

    Details: This update for openssh-openssl1 fixes the following issues: Security issues fixed: - 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) Following non-security issues were fixed: - Fix for sftp client because it returns wrong error code upon failure (bsc#1091396) - Stop leaking File descriptors (bsc#964336)
