http://secunia.com/advisories/37185/

DESCRIPTION:
A vulnerability has been reported in Bftpd, which potentially can be
exploited by malicious users to cause a DoS (Denial of Service).

The vulnerability is caused due to the "bftpdutmp_log()" function in
bftpdutmp.c not properly NULL-terminating the ut.bu_host member and
can potentially be exploited to cause a crash.

Successful exploitation may require that the "RESOLVE_CLIENT_IP"
option is set to "yes".

The vulnerability is reported in versions prior to 2.4.

SOLUTION:
Update to version 2.4.
