ProFTPD 1.2.0pre4 mkdir Command Directory Name Handling Remote Overflow

Critical Nessus Plugin ID 10190


The remote FTP server is prone to a buffer overflow attack.


It was possible to crash the remote FTP server by creating a large number of nested directories and then trying to upload a file. This issue is known to affect ProFTPD, although other FTP servers may be affected as well.

It is likely that a remote attacker can leverage this issue to execute arbitrary code on the remote host, subject to the privileges under which the service runs.


Configure the service so that directories are not writable by 'anonymous' or any untrusted users.

If running ProFTPD, upgrade to version 1.2.0pre6 or later; otherwise, contact the vendor to see if an update exists.
