However, the majority of these reports involve sites that have detected intruders scanning for the presence of these tools. Because of this, we encourage you to investigate any unexplained network traffic. The advisory also provides advice for system and network administrators, end users, software developers, and distributors. Very recently, we have received a few reports of intruders scanning for and exploiting a remote buffer overflow vulnerability in various FTP servers. By supplying carefully designed commands to the FTP server, intruders can force the server to execute arbitrary commands with root privilege.
Intruders can exploit the vulnerability remotely to gain administrative access.
