  TCP/IP and land attack? 
 The Question is:
 
What versions of TCP/IP implementations on Open VMS platforms resist the
land.c denial of service attack?
 
 The Answer is:
 
  This was remedied in TCP/IP Services UCX V4.1 and UCX V4.2 on 10-Apr-1998,
  and systems with a UCX$BGDRIVER.EXE image dated on or after 10-Apr-1998
  should be sufficient.  The OpenVMS Wizard does not believe that the TCP/IP
  Services V5.0 was effected.
