CVE-2018-15473

Priority
Description
OpenSSH through 7.7 is prone to a user enumeration 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.
Notes
sarnoldopenssh-ssh1 is provided for compatibility with old devices that
cannot be upgraded to modern protocols. Thus we may not provide security
support for this package if doing so would prevent access to equipment.
openssh-ssh1 is a *client-only* package, no server-side facility, so
there is no path to leak data
