From the Intro:

Microsoft has recently implemented in many Windows versions a new security feature named
« Structured Exception Handling Overwrite Protection » [1 & 2]. Those systems are:

• Microsoft Windows 2008 SP0
• Microsoft Windows Vista SP1
• Microsoft Windows 7

We did not found any known attack aiming at defeating this new feature but only many papers
describing the feature itself and its robustness. Indeed, SEHOP seems to be so reliable that
Microsoft released a patch in order to activate this security feature by default on all programs. Is it
already the end of stack overflows under Microsoft Windows? Not yet, but under some
circumstances, as we will explain below.
