The security flaw resides in a part of IE that handles CSS, or Cascading Style Sheets, tags. As a result, the browser under-allocates memory, allowing data to be overwritten in memory vtable pointers. By spraying memory with special data, an attacker can cause IE to execute code. The report is the latest reminder of the benefits of moving to the latest version of IE – or to a different browser altogether. Those who must use IE versions 6 or 7, should consider augmenting it with EMET, Microsoft's tool for locking down older applications. It can be used to add DEP and other security mitigations to a variety of programs, including IE and Adobe Reader.

Not so much rumor mill, but a heads up...
