EFTP vulnerable to two DoS attacks
----------------------------------------------------------------------------



SUMMARY

 <http://www.eftp.org/> EFTP is an FTP server and client solution that
allows encrypted FTP connections between the providing FTP server and the
client. The product contains two security vulnerabilities that allow a
remote attacker to cause a Denial of Service attack against the product.

DETAILS

First attack:
Send a buffer of 2100 characters upon connection will crash the server.

Second attack:
Connect to the server with a non-FTP program (something you write by
yourself). Send some characters, and disconnect without sending a '\r\n'.
The server will crash immediately.

Vendor status:
Vendor was contacted on the 26th of August; no response was received since
then.


ADDITIONAL INFORMATION

The security hole was discovered by  <mailto:expert () securiteam com>
