"Several security problems were fixed in OpenSSH :

  - 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 hander 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 usernames on
    some platforms."
