USN-209-1: SSH server vulnerability

Publication date

18 October 2005

Overview

SSH server vulnerability

Releases

Details

An information disclosure vulnerability has been found in the SSH
server. When the GSSAPIAuthentication option was enabled, the SSH
server could send GSSAPI credentials even to users who attempted to
log in with a method other than GSSAPI. This could inadvertently
expose these credentials to an untrusted user.

Please note that this does not affect the default configuration of the
SSH server.
