|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.
