Our approach is built around a software containment system called the inner-sandbox that is designed to prevent unintended interactions between a native code module and the host system. The inner-sandbox uses static analysis to detect security defects in untrusted x86 code. Previously, such analysis has been challenging due to such practices as self-modifying code and overlapping instructions. In our work, we disallow such practices through a set of alignment and structural rules that, when observed, enable the native code module to be disassembled reliably and all reachable instructions to be identified during disassembly. With reliable disassembly as a tool, it's then feasible for the validator to determine whether the executable includes unsafe x86 instructions.
