NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh-askpass package and not the openssh-askpass package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
