The proftpd version that was distributed in Debian GNU/Linux 2.1
had several buffer overruns that could be exploited by remote
attackers. A short list of problems:
* user input was used in snprintf() without sufficient checks
* there was an overflow in the log_xfer() routine
* you could overflow a buffer by using very long pathnames

Please not that this is not meant to be an exhaustive list.

In addition to the security fixes a couple of Y2K problems were
also fixed.

We have made a new package with version 1.2.0pre9-4 to address
these issues, and we recommend to upgrade your proftpd package
immediately.

will fetch the file for you
dpkg -i file.deb
