Debian Security Advisory

Debian FTP packages -- Buffer overflow in some FTP servers

Date Reported:

10 Feb 1999

Affected Packages:

proftpd, wu-ftpd-academ

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-1999-0911.
CERT's vulnerabilities, advisories and incident notes: CA-1999-03.

More information:

The wu-ftpd-academ and proftpd packages distributed in Debian GNU/Linux 2.0 (hamm) are vulnerable to a buffer overflow. It is possible to gain shell access to the machine, and we recommend upgrading these packages immediately.

Extract from the Netect report in CA-1999-03:
Intruders who are able to exploit this vulnerability can ultimately gain interactive access to the remote ftp server with root privilege.

If you are using Debian GNU/Linux 2.1 (slink) you should download a new version. Note that wu-ftpd will install in a disabled state on some configurations; you can enable wu-ftpd by uncommenting the line for /usr/sbin/ftpd in /etc/inetd.conf and running /etc/init.d/netbase reload. The line for /usr/sbin/in.ftpd should remain disabled.
