       SSRT0756U & SSRT0776U - Under certain circumstances,
                               remote systems may create a potential

       SSRT0740U - Under certain circumstances, a remote system may
                   take over packets destined for another host and
                   create a potential denial of service.

    FTPD (Severity High)

       SSRT0762U- This is a updated correction patch for the ftp
                  daemon failure when using a globbing string of
