DESCRIPTION:
NetJackal has discovered a vulnerability in Easy Chat Server, which
can be exploited by malicious people to cause a DoS (Denial of
Service).
The vulnerability is caused due to a boundary error in the processing
of the "username" parameter sent to the application through the web
interface. This can be exploited to crash the server by sending a
specially crafted HTTP request containing a overly long "username".
