I have the following in syslog (and in /var/log/messages):

Nov 20 01:18:12 localhost SERVER[21311]: Dispatch_input: bad request
line
'BBÜóÿ¿Ýóÿ¿Þóÿ¿ßóÿ¿XXXXXXXXXXXXXXXXXX%.156u%300$n%.21u%301$nsecurity%302$n%.192u%303$n\220\220\220\220\220\220\220\220\220

and so on and so on and so on.

It's repeated at one second intervals between 01:18:12 and
01:18:47---the same message followed by the same long sequence of
garbage-characters, with a new PID each time.  There was nobody working
on the machine at that time. There was a CRON job that ran at 01:08:01
and then again at 01:23:01. There are no other jobs like SERVER
reported in the logs, before or after these events.

I've not seen anything like this before. Does anyone else recognize
it or have an idea about what the source might be?

This is a Debian `testing' system with kernel 2.4.14; no web server
running.

Any help would be greatly appreciated,

Jim
