ProFTPD mkdir Buffer Overflow

critical Nessus Plugin ID 10189

Synopsis

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

Description

It is possible to crash the remote FTP service by creating a large number of nested directories with names no longer than 255 chars. 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.

Solution

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.
