Bind (DNS) listens on that port.  Even if there weren't any current
exploits for bind, there are enough historical ones that people will
always be probing that port, looking for ancient installations that
haven't been upgraded.

There was recently a new bind exploit discovered.  The cracking frenzy
that followed has not died down yet, despite the fact that all major
vendors have fixed their systems.  See
http://www.debian.org/security/2001/dsa-026
for debian's report on the vulnerability.
