Hi all!

On SecurityLab.ru forum an exploit code was published by an anonymous user.Reportedly it must have caused Skype massive disconnections today.

The PoC uses standard Skype client to call to a specific number. This callcauses denial of service of current Skype server and forces Skype toreconnect to another server. The new server also "freezes" and so on ... theentire network.
