Kadu 0.x

DESCRIPTION:
Piotr Bania has reported a vulnerability in Kadu, which can be
exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error in the Kadu client within
the handling of image send requests. This can be exploited to crash a
vulnerable client by sending a large number of image send requests.
The user will reportedly be blocked by the server for a period of
time after the client is restarted.

Successful exploitation requires that the user has added the attacker
to his user list.

The vulnerability has been reported in version 0.4.3. Other versions
may also be affected.

SOLUTION:
Add only trusted users to the user list.
