A bug was found in the way the OpenSSH server handled the MaxStartups
and LoginGraceTime configuration variables. A malicious user could
connect to the SSH daemon in such a way that it would prevent
additional logins from occuring until the malicious connections are
closed. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-2069 to this issue.
