Tan Chew Keong SIG^2 2004/07/30 http://www.security.org.sg/vuln/bjd361.html Moodle up to 1.4 Moodle newer than 1.4 Buffer Overflow The remote host is running BlackJumboDog FTP server. This FTP server fails to properly check the length of parameters in multiple FTP commands, most significant of which is USER, resulting in a stack overflow. With a specially crafted request, an attacker can execute arbitrary code resulting in a loss of integrity, and/or availability. The server should be deactivated or de-installed if not necessary. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 2181). Try to prevent unwanted connection attempts by filtering traffic with firewalling.
