Control-Flow Hijacking

Abstract

Memory corruption errors in C/C++ programs remain the most common source of security vulnerabilities in today's systems. Over the last 10+ years the security community developed several defenses [4]. Data Execution Prevention (DEP) protects against code injection -- eradicating this attack vector. Yet, control-flow hijacking and code reuse remain challenging despite wide deployment of Address Space Layout Randomization (ASLR) and stack canaries. These defenses are probabilistic and rely on information hiding.
