We have been tracking this issue. Microsoft has an excellent write up on this. Some of my clients and my own company received alerts directly from Microsoft. If you are a heavy ASP.Net user please look into these issues and take proper steps for work around and patch.

MSFT is listing a WebCast on the OOB Patch [1]

Also a couple of great write ups and release. [2]
