DSA-032-1 proftpd -- proftpd running with incorrect userid, erroneous file removal

Date Reported:

07 Mar 2001

Affected Packages:

proftpd

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2001-0456.

More information:

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

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.
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.
