An update that solves one vulnerability and has two security fixes can now be installed.

Description:

This update for openssh fixes the following issues:

Following security issues have been fixed:

• 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]
