Package: proftpd
Vulnerability: remote DOS & potential buffer overflow
Debian-specific: no

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

1. There is a memory leak in the SIZE command which can result
in a denial of service, as reported by Wojciech Purczynski. This is
only a problem if proftpd cannot write to its scoreboard file; the
default configuration of proftpd in Debian is not vulnerable.

2. A similar memory leak affects the USER command, also as
reported by Wojciech Purczynski. The proftpd in Debian 2.2 is
susceptible to this vulnerability; an attacker can cause the
proftpd daemon to crash by exhausting its available memory.

3. There were some format string vulnerabilities reported by
Przemyslaw Frasunek. These are not known to have exploits, but have
been corrected as a precaution.

All three of the above vulnerabilities have been corrected in
proftpd-1.2.0pre10-2potato1. 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.
