OptiSoft Blubster Remote Denial of Service Attack

It has been reported that Blubster is prone to a remote denial of service vulnerability due to a port flooding attack on TCP port 701. The problem is reported to present itself when a remote attacker floods port 701 with voice chat session requests. This issue may cause the software to crash resulting in a denial of service to legitimate users.

This attack may not be logged, therefore allowing an attack to exploit this issue persistently.
