proftpd mkdir buffer overflow

Vulnerability Assessment Summary Checks if the remote ftp can be buffer overflown Detailed Explanation for this Vulnerability Assessment It was possible to make the remote FTP server crash by creating a huge directory structure with directory names not being longer than 255 chars. This is usually called the 'proftpd buffer overflow' even though it affects other FTP servers. It is very likely that a possible hacker can use this flaw to execute arbitrary code on the remote server. This will give him a shell on your system, which is not a good thing. Solution : upgrade your FTP server. Consider removing directories writable by 'anonymous'.
