<bug_vulnerability_class>Buffer Overflow</bug_vulnerability_class>
<bug_description>The Serv-U FTP server is a well-known ftp server for Windows operating systems. A buffer overflow in the LIST command allows an attacker to crash the server or to run arbitrary code. An attacker needs to send more than 134 bytes with the -I argument.</bug_description>
<bug_solution>If the ftp server is not used it should be de-installed or de-activated. Install the newest patch or bugfix to solve the problem or upgrade to the latest software version which is not vulnerable anymore. Additionally limit unwanted connections and communications with firewalling.</bug_solution>
