    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.
