Several security problems were fixed in OpenSSH 4.4 and the bug fixes were
back ported to the openssh versions in our products.

- CVE-2006-4924: A denial of service problem has been fixed in OpenSSH which could
be used to cause lots of CPU consumption on a remote openssh server.

- CVE-2006-4925: If a remote attacker is able to inject network traffic this could
be used to cause a client connection to close.

- CVE-2006-5051: Fixed an unsafe signal handler reported by Mark Dowd. The signal
handler was vulnerable to a race condition that could be exploited to perform a
pre-authentication denial of service. This vulnerability could theoretically lead to
pre-authentication remote code execution if GSSAPI authentication is enabled,
but the likelihood of successful exploitation appears remote.

- CVE-2006-5052: Fixed a GSSAPI authentication abort that could be used to determine
the validity of user names on some platforms." );
