Can you hear that? It's a Skype vulnerability.

Those of you out there that really enjoy the free (or low cost) calling afforded by Skype need to be aware of a recent vulnerability found in Skype for Windows. TippingPoint's Zero Day initiative is responsible for the disclosure and pushing Skype to patch the issue. So update your Skype as soon as you can. You want to make sure you have version 3.6.0.216 or later.
