I think the simplest fix is to upgrade to a more recent version.

As far as apt-get is concerned this is the most recent version, but I
suppose there is nothing stopping anyone downloading and installing
the latest release.
I tried the DenyFilter \*.*/ workaround mentioned at
proftpd.linux.co.uk/critbugs.html
and it seems fine with this line in the conf file.  All you get now
is:

200 PORT command successful.
