ChangeLog for 3.21.9 (beta)

Version 3.21.9 [BETA] (rgerhards), 2008-12-04

• re-release of 3.21.8 with an additional fix, that could also lead
  to DoS; 3.21.8 has been removed from the official download archives

• security fix: imudp emitted a message when a non-permitted sender
  tried to send a message to it. This behaviour is operator-configurable.
  If enabled, a message was emitted each time. That way an attacker could
  effectively fill the disk via this facility. The message is now
  emitted only once in a minute (this currently is a hard-coded limit,
  if someone comes up with a good reason to make it configurable, we
  will probably do that).
