  Log:
  Correct a pair of buffer overflows in the telnet(1) command:
  
  CAN-2005-0468) A heap buffer overflow in env_opt_add() and related
  functions.
  
  (CAN-2005-0469) A global uninitialized data section buffer overflow in
  slc_add_reply() and related functions.
  
  As a result of these vulnerabilities, it may be possible for a malicious
  telnet server or active network attacker to cause telnet(1) to execute
  arbitrary code with the privileges of the user running it.
  
  These fixes are based in part on patches
