Package: proftpd
Vulnerability: proftpd running as root, /var symlink removal
Debian-specific: yes

The following problems have been reported for the version of
proftpd in Debian 2.2 (potato):

1. There is a configuration error in the postinst script, when
the user enters ‘yes’, when asked if anonymous access should be
enabled. The postinst script wrongly leaves the ‘run as uid/gid
root’ configuration option in /etc/proftpd.conf, and adds a ‘run as
uid/gid nobody’ option that has no effect.

2. There is a bug that comes up when /var is a symlink, and
proftpd is restarted. When stopping proftpd, the /var symlink is
removed; when it’s started again a file named /var is created.

The above problems have been corrected in
proftpd-1.2.0pre10-2.0potato1. We recommend you upgrade your
proftpd package immediately.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

You may use an automated update by adding the resources from the
footer to the proper configuration.
